  • MeJournal Acquisitions/ Reference Librarian Art,Communication Studies & Mass Media liaison Formerly Electronic Resources Librarian, Chair of Scholarly Communications Committee at NULCreated data model and programmed database application for a complex, long-term political science content analysis projectAs librarian, created data models and programmed database applications:To track resources purchased per year, expenditures, and budgets (the main goal was an easy-to-use interface for tech averse librarians)To track resources in a large variety of ways (LC, Dewey, Year, Language, and so on), along with Circulation and Expenditure informationCitation Analysis prototypeAT MSU, currently working with a graduate student team on a tool to track electronic resource usage statistics: SUSHI client, repository, and reporting functionalityPrevious Career: Treasurer of Software Development Company and Business Manager of Market Research Firm (basically a social science lab for hire) The goals of this workshopOverview awareness of Open Access, Digital Humanities, Text Analysisincluding familiarity with significant concepts and jargon in these areasas well as a notion of some of the differences among the leading thinkers in these areas.Awareness of at least three tools that can be used for text analysisalong with some ideas about how to apply these tools to actual projectsas well as some ideas about how these tools might be used for pedagogical purposesI want you to walk out of here comfortable enough to consider using Voyant or CATMA on your own and, if you want to pursue any of the areas under discussion further, I want you to have some confidence that you know how to proceed.
  • I’ll apologize in advance for all of the text on the slides for the overviews of the Digital Humanities and Text Analysis. There are several important essays in both areas. To give you a sense of these papers, I provided numerous quotations. I will not be reading all of the quotations, although I will draw your attention to several as we move along.If you don’t have time to read the quotations today, you will find them at the website in the slideshow. I have also included a works cited section in the slideshow.
  • Some DH practitioners don’t seem aware of the importance of Open Access, but it is an essential background concept.Origins of OA in serials crisisOld Publishing Model: Scholar signs away copyright to publisher for freeNew Publishing Model: Scholar retains copyright (library as publisher, other “platinum” OA), or at least retains some rights from commercial publishersOA termsOA venuesThe key to Open Access is rights.
  • Alternative to Open Access is the Public DomainIn U.S., everything published before 1923, and a selection of post 1923 publications depending on a variety of conditionsCopyright shouldn’t cover text analysis, but publishers hire expensive lawyers to block usage in attempt to profit by another means. 4 conditions of Fair Use:The purpose and character of the use, including whether such use is of commercial nature or is for nonprofit educational purposesThe nature of the copyrighted workThe amount and substantiality of the portion used in relation to the copyrighted work as a wholeThe effect of the use upon the potential market for, or value of, the copyrighted work
  • Traditional origin story: one protagonist on a questThe genealogy also sometimes acknowledges other ancestors, such as “quantitative approaches to style and authorship studies” (Hockey, 2004)What is excluded and why?See content analysis studies on art (Gordon, 1952; Paisley, 1968), cartoons (Ehrle and Johnson, 1961), music (Paisley, 1964; La Rue, 1967), the readability of texts (Gray and Leary, 1935; Flesch, 1943; Lorge, 1944; Kearl, 1948), and so forth (from Holsti, 1969).How “should” humanists engage with tools? How “should” humanists conduct research?Ex: Can humanists utilize social scientific methodologies? … and would this lead toward a “consilient” humanities? (a humanities consistent with scientific understanding vs. current “quasi-creationism,” a la Gottschall’s formulation)There is a great deal of argumentation about methodology, which I’ll try to cover in some degree later. For now:The truth is that there don’t seem to be many humanists who actually “get” scientific methodology More often, scientific jargon is used (words like hypothesis and falsifiability), but the usage can be misleading. Or quantification is used to make a “case,” but the case is actually a rhetorical argument, not the report of a scientific study. My position is nuanced. I think we need to beware of the abuse of scientific terms for non-scientific studies. I do think there is a place for scientific methodologies in many kinds of humanities studies, so, for example, the humanities could learn much by studying content analysis, but:I tend to follow Stephen Ramsay, whom you’ll meet later. He makes the case for “homegrown” humanities-based methodologies.And anyway, should the computer really be at the heart of the story?The computer concordance replaces book concordances and index card concordances, for example. Isn’t the computer just a step on a ladder? So what is the ladder?(how much longer will we be thinking in terms of “computers” as such anyway? How many computers do you have in your home – do you know?)
  • Digital Humanities vs. The Digital HumanitiesSingular: A field itself, standing on its own: theory(ies), programs, departments, majorsPlural: A variety of research in a range of humanities fieldsSingular: The digital as object of study? Leading to newly emergent object(s) of study?Plural: The digital (information technology) as instrument(s) of study?Singular seems to be preferred in writing, while plural often occurs when spoken … or is the singular the formal version and the plural informal?Plural: Recalls the history of the field - Humanities ComputingHumanities ComputingText Digitization ProjectsTool DevelopmenteResearch (…eScience, Social Sciences Computing)“Digital Humanities” as a trend, as a fraud…The Tweeting Humanities?Actually, there seem to be vastly more DH practitioners not tweeting or blogging than doing so. However, Kirschenbaum is certainly right that there do seem to be “cliques” among the folks active on Twitter.Are the (relatively) few DH practitioners on Twitter representative of the field? DH tweets and blogs remain useful (if not always efficient)
  • An awkward sentence, but nicely inclusive of the ongoing range of scholarly activity called “Digital Humanities”- Note that this blog post talks much about the DH “big tent,” but the substantive literature on and about the field reveals deep, deep rifts
  • 4 Part Article Series, of which this is #2Note his observations of the fieldSvensson refers to Gary Hall: “It follows that the consequences and implications of digital media for research into cultural studies themes, problematic, and questions cannot be explored simply by using the recognized, legitimate, preconstituted, disciplinary forms of knowledge: literary studies, philosophy, sociology, history, psychoanalysis, and so on. Digital media change the very nature of such disciplines, rending them ‘unrecognizable’ as Derrida says of psychoanalysis.” (Hall 2008, 81)The reference anticipates the positions of some later papers, of which I’ll mention 2 in a moment: Alan Liu, Andrew Prescott
  • Not really a genealogy: really, a partial lit reviewShe tracks some of the impacts of DH practices on various aspects of scholarship, including methods, expectations, organization, and scope of practice. SEE her summary of Ruhleder:The Thesaurus Linguae Graecae (TLG) is a digital collection of “the canon of Greek authors and works,: which was “started in 1972 by Theodore Brunner at the University of California, Irvine.” “this resource had a profound restructuring effect on knowledge production in the field of Classics” (Dalbello 489)She also discusses concepts such as ‘frenetic’ reading as ‘meta reading’(492) which we will take up, at least implicitly, when we discuss approaches to text analysis.
  • Note the big play at the start – does he deliver?Does Prescott accurately portray the range of the Digital Humanities?Does Prescott offer real solutions? Or are these solutions already encompassed by DH? (recall all of Svensson’s modes of engagement; and consider, for example, topics covered at conferences, such as the Chicago Colloquium … video game platform studies, etc.)Is this scholarly colonialism? Simply naïvete? Showmanship? Valid opinion and worthy of pursuit?
  • Interesting essay too long to handle fairly here, but Liu shows little interest himself in “fairness,” so I’m not troubled.He claims “unusual breadth” in his construction of DH, but if anything, his DH is unusually narrow … in order to provide a basis for his next rhetorical move?Note how he sets up a problem for DH, so that DH must be “rescued” from its practitioners. While he may be right in interesting ways, the colonialism of the project staggered me at first reading.“…the single most important theoretical development in the digital humanities in recent years has been the explosion of non-empirical interpretive paradigms”Liu is right that there have been exciting developments, but his concept of the empirical throughout is bizarre. Maybe he is trying to strike a Derridean pose, but the truth is that empiricism embraces the experiential, so the new paradigms of play and deformance are as empirical as other observational methods.Liu’s references to the “text-oriented side of the field” are usually back-handed, at best. I think the last quote requires some empirical testing because, given my own reading, it seems to me he must be disallowing any evidence that may contradict him.
  • Willard McCarty’s essay seems to me to be just a little bit wiser and farther-seeing than the previously described papers. SEE the year.
  • If you are just starting to think about text analysis or listen in on conversations about text analysis, the vocabulary might seem off-putting, but there is really very little to it….In addition, if you look at text analysis tools, you might feel overwhelmed by the options seeming available, but you will quickly notice that the options to be variations on a limited set of themes…
  • So let’s admit Jockers is a heavy-handed writer, thus he characterizes critical insights as “random ‘things’” and tells us what we “must” do, but next, let’s consider what he’s offering.Jockers details many interesting applications of macroanalysis“by providing … a fuller sense of the literary-historical milieu” (28) of textsAs useful corrective to inaccurate literary historical generalizationsFor authorship attribution based on type-token ratio, or by analysis of the use of “little words,” and so onFor exploring genre, period, gender and so onFor exploring influenceTo compare literary historical or comparative literature concepts, such as the idea of “national voice”Jockers does seem at times to have lost sight of the trees for the forest. It’s hard to imagine him actually close reading a book, esp The Wasteland, In Parenthesis, etc.For some kinds of studies, I think Jockers is just plain right. Some kinds of literature problems can be solved (esp. something like Authorship Attribution). But is this criticism? We’ll talk about this more.
  • I quote Moretti at extreme length, but I want to be clear about the origins of the phrase “Distant Reading” – which has been a marketing slogan to rival “Digital Humanities”Moretti was arguing for a study of world literature which would not rely on close reading alone, but would also, or perhaps instead, rely on the scholarship of others.However, his formulation of Distant Reading does nicely encompass computer-assisted text analysis.As it happens, Moretti has also gone on to direct the Stanford Literary Lab (founded with Matthew Jockers). He has been a leader of the kind of quantitative, computer-assisted text analysis studies we saw with Jockers.
  • “Style, Inc.: Reflections on 7,000 Titles” (lots of graphs descriptive of changes in … titles)“Network Theory, Plot Analysis” – see Figure“The Slaughterhouse of Literature”Here we might observe the danger of quantitative analysis seeming scientific, but not actually conducted scientifically. He conjectures that the ongoing popularity of Sherlock Holmes (“sociallysupercanonical right away, but academically canonical only a hundred years later), by Arthur Conan Doyle, results from Doyle’s use of clues in his stories. He compares Doyle’s stories to those of his contemporaries, tracking whether and how clues are used in their stories. Moretti finds what he sets out to find. Doyle does use clues more often than his contemporaries (but perhaps a little less consistently than Moretti expected)He does not set up a control or look for disconfirmation or even consider other possibilities. (ex: How about character traits – Sherlock is modelled on Poe’s Dupin. Sherlock on TV today relies on the character traits of both, much less on clues.)Looking ahead, we might say that Moretti succeeds because he works in the spirit of “inventio,” he “freely employs the rhetorical tactics of conjecture” (Ramsay 16) – I’m quoting the words of Stephen Ramsay.
  • If you pick up just one book on text analysis, I suggest Stephen Ramsay’s Reading Machines. 98 pages of collected essays.“…for decades the dominant assumption within humanities computing … has been that if the computer is to be useful to the humanities, its efficacy must necessarily lie in the aptness of the scientific metaphor for humanistic study. This work takes the contrary view and proposes that scientific method and metaphor … is, for the most part, incompatible with the terms of humanistic endeavor.” (Ramsay x)
  • I think Ramsay suggests the wisest path forward for a literary criticism that makes use of quantification (perhaps excepting some kinds of questions, as we saw in Jockers, but then, these may not be literary critical).In Ramsay, I think we see the best encapsulation of what Liu considered to be the “new interpretive paradigm.”In addition, Ramsay writes about “deformance” (from Jerome McGann and Lisa Samuels) and “tamperings” (from Estelle Irizarry), in which a text is made unfamiliar, thus leading to new thinkings … there is a cottage industry in talking about text analysis as play…
  • Sinclair also quotes Mike McCullough from Abstracting Craft, 1996: “… it is a distinct advantage of computation to introduce play; this is a natural consequence of working in bits.”I have not read McCullough, in part because my library offers access only through a very bad online interface (humorously enough), but one might see how the chapter on “Play” might help broadly to inform a discussion of play with Text Analysis tools:“There is much to be said for play in a medium. If a medium is defined by its affordances and constraints, then learning consists of exploring these properties. Experimentation is especially useful for becoming familiar with constraints: we learn from our mistakes. We must accept that beginning work in a new medium will be full of setbacks. There will also be fortuitous discoveries, however, particularly of affordances. Design is not only invention, but also sensitivity to a medium. Craft cannot be merely in service of technique, or of inappropriately conceived ends. The craftsman must begin to feel something about the artifacts, and only certain moves will feel right.”
  • These quotations draw our attention to pedagogical aspects of Text Analysis Tools. We’ll talk more about pedagogy later when thinking about projects, but I want to note here two issues. Students can use TA tools possibly to improve, or at least to reflect upon their own writing. We must ask whether students not taught TA tools are being deprived, are not being taught competencies that might be growing increasingly “basic”
  • From a topic modeling (LDA) perspective, a text consists of some number of topics, each of which makes up some percent of the text. A topic can be thought of as a “bag of words.” We can think of a text as resulting from a number of random drawings from those bags of words based on the percentage allocation of topics (and the numbers of various words in those bags will dependon the percentage allocation of words within those topics).“One way to think about how the process of topic modeling works is to imagine working though an article with a set of highlighters. As you read through the article, you use a different color for the key words of themes within the paper as you come across them. When you were done, you could copy out the words as grouped by the color you assigned them. That list of words is a topic, and each color represents a different topic. Note: this description is inspired by the following illustration from David Blei’saricle, which is one of the best visual representation of a topic I’ve found.” (Brett 12)My caveat: the computer does not know the meanings of the words. The algorithm finds topics based on the co-occurrence of the words: “They look like ‘topics’ because terms that frequently occur together tend to be about the same subject” (Blei 9)
  • This graphic represents a (perhaps gross) simplification of the most common form of topic modeling (Latent Dirichlet Allocation, or LDA)
  • What if I want to topic model Whitman’s 1892 Leaves of Grass? I decide to treat each poem as a document, so I need to prepare the text so that TMT will read each poem as a document (and I also have to make some decisions about what will count as words).
  • Leaves of grassMake copies of the original textFor complex clean-up, the precise order of steps might take several attempts to get right.Regular expressions can help a great deal
  • If, instead of topic modeling, I want to visualize various aspects of a text in Voyant, my text preparation process is very different. I simply remove anything that will cause my word counts to go awry.

  • Content Analysis is a large topic that is not easy to cover in an overview, because we can’t cover research design or methodological issues, which are the core of the topic.I’m introducing this topic because I will demonstrate CATMA in a little bit. I think it would be worthwhile to look more closely into content analysis in order to make the best use of CATMA.I consider content analysis to be too important to skip. Many digital humanists are pursuing some form of content analysis, sometimes without knowing it as such, and they could really benefit from a wider understanding. And anyway, a lot of great humanities work is done in the social sciences.Because nothing is easy, I should point out that my use of the label “Content Analysis” here, although traditional, is not uncontroversial. The term has historically been used (and continues to be used by many) to include a wide variety of both quantitative and qualitative studies of text content. However, an important textbook on the topic, The Content Analysis Guidebook, by Kimberly A. Neuendorf, narrowly defines content analysis. She distinguishes numerous kinds of “message analysis” studies. Her informal use of the label “message analysis” in her text coincides, I think, with the historical use of “content analysis,” but I haven’t made a study of this thought.Rhetorical Analysis: “The analyst engages in a reconstruction of manifest characteristics of text … such as the message’s construction, form, metaphors, argumentation structure, and choices.”Narrative Analysis: “…involves a description of formal narrative structure”Discourse Analysis: “engages in characteristics of manifest language and word use … connection of words to theme analysis of content and the establishment of central terms.”Structuralist (or Semiotic) Analysis: “Technique aims at deep structure, latent meanings, and the signifying process through signs, codes, and binary oppositions.”Interpretative Analysis: “focus … on formation of theory from the observation of messages and the coding of those messages)Conversation Analysis: “analyzing naturally occurring conversations”Critical AnalysisNormative Analysis: prescriptive or proscriptive(Neuendorf 5-8)
  • Quantitative/ Qualitative:In quantitative analysis, things are counted by category. The counts (frequencies) allow statistical analyses (which vary depending on the kinds of counts)Ole Holsti proposed that there might be such a thing as qualitative content analysis, depending not on frequencies, but on whether some category of content appears (and perhaps how and when it appears) (Holsti 5-11), but he nevertheless called for an objective and systematic method to apprehend these appearancesBruce Berg also suggests qualitative analysis is possible: “Analysis of the data once organized according to certain content elements should involve consideration of the literal words in the text being analyzed, including the manner in which these words have been offered … content analysis is not a reductionistic, positivistic approach. Rather, it is a passport to listening to the words of the text, and understanding better the perspective(s) of the producer of these words.” (Berg 242)Deductive/ InductiveNeuendorf acknowledges that it might be necessary for the researcher to immerse herself in some data to identify variables: she calls this the “Grounded or Emergent Process of Variable Identification” (Neuendorf 102-103)I have also seen this process referred to as “Open Coding” (Berg 245-6)Manifest/ Latent Content: Neuendorf: “…it is perhaps more useful to think of a continuum from ‘highly manfest’ to ‘highly latent’” (Neuendorf 23)Content/ Form: Consider Neuendorf’s study of gender and violence imagery in music videosReliability, Validity, Generalizability, ReplicabilityUnitizing:units of sampling, of analysis, of data collection; recording units; etc.
  • Example: Track the use of gender pronouns in company policy manuals over a period of time, or between two or more periods of time.
  • Neuendorf would circumscribe some of the uses on this list more carefully than Holsti
  • If possible, show CATMA online: login, load doc, add markup doc, create some tags.
  • Stop Calling Office Parks “nondescript” – a trivial, but fascinating example of how a text analysis tool might be used.
  • Note how “Word Trends” seems to have a different setting from default Voyant so that multiple words cannot be tracked at once. I might be able to figure out how to enable multiple words, but how much time do I spend?

  • Overview: Digital Humanities . 1 http://openresearch.weebly.com/digital-humanities-eresearch.html “In 1949, an Italian Jesuit priest, Father Roberto Busa, began what even today is a monumental task: to make an index verborum of all the words in the works of St. Thomas Aquinas and related authors, totaling some 11 million words of medieval Latin. Father Busa imagined that a machine might be able to help him, and, having heard of computers, went to visit Thomas J. Watson at IBM in the United States in search of support … The entire texts were gradually transferred to punched cards and a concordance program written for the project.” (Hockey online) “The History of Humanities Computing,” Susan Hockey, 2004 7
  • Overview: Digital Humanities . 2 “The real origin of that term *digital humanities+ was in conversation with Andrew McNeillie, the original acquiring editor for the Blackwell Companion to Digital Humanities. We started talking with him about that book project in 2001, in April, and by the end of November we’d lined up contributors and were discussing the title, for the contract. Ray *Siemens+ want ‘A Companion to Humanities Computing’ as that was the term commonly used at that point; the editorial and marketing folks at Blackwell wanted ‘Companion to Digitized Humanities.’ I suggested ‘Companion to Digital Humanities’ to shift emphasis away from simple digitization.” (John Unsworth quoted in Kirschenbaum 2-3) “Twitter, along with blogs and other online outlets, has inscribed the digital humanities as a network topology, that is to say, lines drawn by aggregates of affinities, formally and functionally manifest in who follows whom, who friends whom, who tweets whom, and who links to what.” (Kirschenbaum 5) “What is Digital Humanities and What’s It Doing in English Departments?” Matthew G. Kirschenbaum, 2010 8
  • Overview: Digital Humanities . 3 “…the digital humanities can be … a nexus of fields within which scholars use computing technologies to investigate the kinds of questions that are traditional to the humanities, or… who ask traditional kinds of humanities- oriented questions about computing technologies.” (Fitzpatrick online) “Reporting from the Digital Humanities 2010 Conference,” Kathleen Fitzpatrick, 2010 9

  • Overview: Digital Humanities . 5 “The Landscape of Digital Humanities,” Patrik Svensson, 2010 5 “paradigmatic modes of engagement between the humanities and information technology: information technology as a tool, an object of study, an exploratory laboratory, an expressive medium and an activist venue.” (Svensson online) “…the digital humanities comprise a field in a loose sense.” (Svensson online) “…it seems quite unlikely that the digital humanities would ever become a fully separate field.” (Svensson online) “The complexity of digital humanities as a ‘field’ comes partly from its disciplinary and institutional diversity, and its multiple modes of engagement with information technology.” (Svensson online) “…one interesting question is whether the digital calls for other modes of investigation, collaboration and making that may be partially incompatible with the epistemic commitments of the established discipline or field.” (Svensson online) 11
  • Overview: Digital Humanities . 6 “A Genealogy of Digital Humanities,” Marija Dalbello, 2010 “This paper explores the history of digital humanities that grappled with the epistemological status of technology, as a major field of contemplation of the effects of new media on writing, reading, and interpretation.” (Dalbello 482) Previous to the TLG, according to Karen Ruhleder, “gaining familiarity with the corpus was a life’s work” (1995), but given the TLG, graduate students could “ask questions that formerly could only be answered through comprehensive reading and experience un the field.” (Dalbello 488) The TLG “had a profound restructuring effect on knowledge production in the field of classics … a broader range of ‘legitimate’ research queries could produce a sense of ‘doing complete work’” so that the “researcher could be free to do more intellectually interesting work rather than focusing on learning the corpus” (Dalbello 489) “Seeing patterns and connections out of context liberates them from an archive, as a signifier that attaches itself to a new meaning; searches through digital corpora can produce radical readings and undermine existing interpretations, thus contributing to a program of critical interpretation,” (Dalbello 493) 12
  • Overview: Digital Humanities . 7 “The term post-human … suggests that our sense of what it is to be human has changed – as Katherine Hayles puts it, the post-human is a state of mind, a realization that mankind has finally understood that it is definitely not the centre of the universe. My concern here is to consider the implications of this post-human state of mind for our understanding and practice of the digital humanities.” (Prescott online) “Making the Digital Human: Anxieties, Possibilities, Challenges,” Andrew Prescott, 2012 “For all the rhetoric about digital technologies changing the humanities, the overwhelming picture presented by the activities of digital humanities centres in the Great Britain is that they are busily engaged in turning back the intellectual clock and reinstating a view of the humanities appropriate to the 1950s...” (Prescott online) “…as far as the digital humanities are concerned, interdisciplinarity is just a cover for the lack of a distinctive intellectual agenda … Another major obstacle preventing the digital humanities developing its own scholarly identity is our interest in method. If we focus on modelling methods used by other scholar, we will simply never develop new methods of our own.” (Prescott online) “We might start by seeking closer contact with our colleagues in Cultural and Media Studies.” (Prescott online) “We should be seeking to provide new perspectives on the way in which technology interacts with text.” (Prescott online) 13
  • Overview: Digital Humanities . 8 “The state of the digital humanities: A report and a critique,” Alan Liu, 2011 “A purely economic rationale for the digital humanities might … be that they re-engineer higher education for knowledge work by providing ever smarter tools for working with increasingly global-scale knowledge resources, all the while trimming the need to invest proportionally in the traditional facilities…” (Liu 2011) “I offer a report on the current state of the digital humanities … I will define it with unusual breadth. “Digital humanities’ will here have a supervening sense that combines ‘humanities computing’ or ‘text-based’ digital humanities … and new media studies …” (Liu 10) “Currently, I fear, the digital humanities are not ready to take up their full responsibility because the field does not posses an adequate critical awareness of the larger social, economic, and cultural issues at stake … the whole amounts to the lack of a mental and policy firewall against postindustrial takeovers of the digital idea …” (Liu 11) “The digital humanities are on the threshold of a new interpretive paradigm. The old paradigm, especially on the text-oriented side of the field, was constraining. That paradigm was empirical … about ‘hypothesis testing and empirical validation’. … The new paradigm allows computers and humans to share responsibility for the full act of interpretation, including the component acts of hypothesis-framing, observation, discovery, analysis, testing, reiterative hypothesis-framing, etc.” (Liu 21) “…the text-oriented side of the digital humanities has been almost wholly uninterested in any social, political, economic, or cultural inquiry into the contexts and implications of information technology.” (Liu 30) 14
  • Overview: Digital Humanities . 9 “….attempts to work toward a theoretical foundation for humanities computing surfaced at the outset of scholarly publication in the field and have been in progress ever since – with no consensus in sight … the considerable variety in how humanities computing is … conceived is a sign of health rather than decay.” (McCarty 1228) “….humanities computing … need not wait on the emergence of a theoretical framework … its semidirected, semicoherent activities are no discredit, rather the norm for an experimental field.” (McCarty 1233) “…the crafted objects of humanities computing are … primary ‘metatheoretical statements’ produced by those who ‘think in things rather than words.’ A new definition of scholarship, demanind new abilities, would seem to follow.” (McCarty 1227) “The question of reinventing our scholarly forms takes us beyond any list of projects to what we might consider the fundamental ‘project’ of humanities computing … This is, in simple but far-reaching terms, epistemological: to ask, in the context of computing, what can (and must) be known of our artifacts, how we know what we know about them, and how new knowledge is made.” (McCarty 1231) “The socioacademic function of humanities computing can be understood as an elaboration of the Galisonian trading zone, which the field establishes as a methodological commons and within it, takes the role of merchant trader among mutually divergent academic cultures.” (McCarty 1232) “Play, apparently without conscious direction, is a recognized factor in scientific discovery.” (McCarty 1232) “Humanities Computing,” Willard McCarty, 2003 15

The concordance is a standard research tool in the humanities that goes back to the thirteenth century. … The challenge before us is to question our procedural habits and presuppositions as to what are legitimate recombinations – to forget the concordance and ask anew how we can analyse text with a computer and whether such computer-assisted interpretations are interesting in and of themselves. We need to play again and make playpens available to our colleagues. … I therefore want to propose a very different image of what a concordance is … I call it a hybrid (or monster) because it is authored not just by the original author, but also by the user’s choices and the procedures used to generate it … it is neither the work of the original author nor that entirely of the provoker of the concordance.” (Rockwell 210,213) 17
  • Overview: Text Analysis . 2 Macroanalysis, Matthew Jockers, 2013 “The literary scholar of the twenty-first century can no longer be content with anecdotal evidence, with random ‘things’ generated from a few , even ‘representative’ texts. We must strive to understand these things in the context of everything else, including a mass of possibly ‘uninteresting’ texts.” (Jockers 8) “Today’s student of literature must be adept at reading and gathering evidence from individual texts and equally adept at accessing and mining digital-text repositories.” (Jockers 9) “At the macro scale , we see evidence of time and gender influences on theme and style. By superimposing these two network snapshots in our minds, we can begin to imagine a larger context in which to read and study nineteenth-century literature. What is clear is that the books we have traditionally studied are not isolated books. The canonical greats are not even outliers: they are books that are similar to other books…” (Jockers 168) “…macroscopic investigation is contextualization on an unprecedented scale.” (Jockers 27-8) “It is the exact interplay between the macro and micro scale that promises a new, enhanced, and perhaps even better understanding of the literary record. The two approaches work in tandem and inform each other. Human interpretation of the ‘data,’ whether it be mined at the macro or micro level, remains essential … The most fundamental and important difference in the two approaches is that the macroanalytic approach reveals details about texts that are for all intents and purposes unavailable to close-readers of the texts.” (Jockers online) See Example Project 18
  • Overview: Text Analysis . 3 Distant Reading, Franco Moretti, 2013 “Writing about comparative social history, Marc Bloch once coined a lovely ‘slogan,’ as he himself called it: ‘years of analysis for a day of synthesis’; and if you read Braudel or Wallerstein you immediately see what Bloch had in mind. The text which is strictly Wallerstein’s, his ‘day of synthesis’, occupies one-third of a page … the rest are quotations … Years of analysis; other people’s analysis, which Wallerstein’s page synthesizes into a system. Not, if we take this model seriously, the study of world literature will somehow have to reproduce this ‘page’ – which is to say: this relationship between analysis and synthesis – for the literary field. But in that case, literary history will quickly become very different from what it is now: it will become ‘second hand’: a patchwork of other people’s research, without a single direct textual reading. Still ambitious, and actually even more so than before (world literature!); but the ambition is now directly proportional to the distance from the text: the more ambitious the project, the greater must the distance be.” (Moretti 47-8, 2000) “Distant reading: where distance … is a condition of knowledge: it allows you to focus on units that are much smaller or much larger than the text: devices, themes, tropes – or genres and systems. And if, between the very small and the very large, the text itself disappears, well, it is one of those cases when one can justifiably say, Less is more. It we want to understand the system in its entirety, we must accept losing something…” (Moretti 48-9, 2000) 19

  • Overview: Text Analysis . 5 Reading Machines, Stephen Ramsay, 2011 “…literary criticism operates at a register in which understanding, knowledge, and truth occur outside of the narrower denotative realm in which scientific statements are made. It is not merely the case that literary criticism is concerned with something other than the amassing of verified knowledge. Literary criticism operates within a hermeneutical framework in which the specifically scientific meaning of fact, metric, verification, and evidence simply do not apply … ‘evidence’ stands as a metaphor for the delicate building blocks of rhetorical persuasion … ‘Verification’ occurs in a social community of scholars whose agreement or disagreement is almost never put forth without qualification.” (Ramsay 7, 2011) “If text analysis is to participate in literary critical endeavor in some manner beyond fact-checking, it must endeavor to assist the critic in the unfolding of interpretive possibilities. We might say that its purpose should be to generate further ‘evidence,’ though we do well to bracket the association that term holds in the context of less methodologically certain pursuits. The evidence we seek is not definitive, but suggestive of grander arguments and schemes.” (Ramsay 10, 2011) “Critics often use the word ‘pattern’ to describe what they’re putting forth, and that word aptly connotes the fundamental nature of the data upon which literary insight relies. The understanding promised by the critical act arises not from a presentation of facts, but from the elaboration of a gestalt, and it rightfully includes the vague reference, the conjectured similitude, the ironic twist, and the dramatic turn. In the spirit of inventio, the critic freely employs the rhetorical tactics of conjecture – not so that a given matter might be definitely settled, but in order that the matter might become richer, deeper, and ever more complicated. (Ramsay 16, 2011) 21
  • “Although it is true that we do not typically ask *students+ to cast yarrow stalks or choose things at random, we do ask them to find some pattern beyond the apparent pattern of the text … We ask them to select, isolate, notice – to consider a small group of sub-patterns from among the infinity of patterns that make up the text. Having done this, we then ask them to re-articulate those patterns in narrative form as elucidations of the texts in which they occur. We call those articulations ‘meanings’, and we call the act of embedding them in a narrative framework ‘interpretation’. … With algorithmic criticism, one would not ask how the ends of interpretation were or were not justified by means of the algorithms imposed, but rather, how successful the algorithms were in provoking thought and allowing insight.” (Ramsay 171, 173, 2003) Overview: Text Analysis . 6 “…the real message of our technology is something entirely unexpected – a writerly, anarchic text that is more useful than the readerly, institutional text … This is, if you like, the basis of the Screwmeneutical Imperative. There are so many books. There is so little time. Your ethical obligation is neither to read them all nor to pretend that you have read them all, but to understand each path through the vast archive as an important moment in the world’s duration – as an invitation to community, relationship, and play.” (Ramsay online, 2010) Reading Machines, Stephen Ramsay, 2011, and other essays “… As with any text-analytical result, we can weave a narrative through the gaps. For this reason, we would do better to say it carves a new path through the document space, which in turn allows us to reread and rethink…” (Ramsay 80, 2011) 22

An engaging activity can be to have students try to find texts on the web that most closely resemble the data profile of their own texts. Do so can provoke interesting results and awaken the curiosity of the students for the relationship between text analysis and linguistic proficiency.” (Rockwell and Sinclair, 2009) “Learning to Read Again,” Fred Gibbs, 2013 24

  • Overview: Topic Modeling . 3 “Topic modeling gives us a way to infer the latent structure behind a collection of documents. In principle, it could work at any scale, but I tend to think human beings are already pretty good at inferring the latent structure in (say) a single writer’s oeuvre. I suspect this technique becomes more useful as we move toward a scale that is too large to fit into human memory.” (Underwood online) “Topic modeling made just simple enough,” Ted Underwood, 2012 “…I’m not sure how much value they will have as evidence. For one thing, they require you to make a series of judgment calls that deeply shape the results you get (from choosing stopwords, to the number of topics produced, to the scope of the collection). The resulting model ends up being tailored in difficult-to-explain ways by a researchers preferences.” (Underwood online) See a variety of Topic Model visualizations “…excitement about the use of topic models for discovery needs to be tempered with skepticism about how often the unexpected juxtapositions LDA creates will be helpful, and how often merely surprising. A poorly supervised machine learning algorithm is like a bad research assistant. It might produce some unexpected constellations that show flickers of deeper truths; but it will also produce tedious, inexplicable, or misleading results.” (Schmidt 50) “Words Alone: Dismantling Topic Models in the Humanities,” Benjamin M. Schmidt, 2012 27
