- 13. Big Data Digital Humanities vs. Small Data Digital Humanities • “Research in Big Data Digital Humanities focuses on large or dense cultural datasets, which call for new processing and interpretation methods” • “..Small Data Digital Humanities regroup more focused works that do not use massive data processing..” • A map for big data research in digital humanities, Frédéric Kaplan
- 14. 1. research the context: know the data about the data (so meta!) How to understand data
- 15. Data versus Metadata Big? Smart? Clean? Messy? Data in the Humanities, Christof Schöch Metadata Metadata Metadata Metadata data data data data data data data data data data data data data data data data About this dataset: Title: Metadata Date Created: Metadata Creator: Metadata Methods Used: Metadata
- 16. 2. research who the data is about How to understand data
- 17. What are historical contexts around their language and style?
- 18. A note on data ethics.
- 19. Zine Librarians Code of Ethics • “Zines are not like mass-distributed books. They are often self- published and self-distributed, and sometimes printed in very small runs, intended for a small audience. In addition, perzines are by definition “personal”, and zinesters may feel different about having their zines distributed in print than they would about having them openly available on the internet or print. This can be especially true in the case of “historical” zines in library collections — for example, a teen girl writing a zine for her close friends in 1994 may not want her zine distributed online or in print 20 years later.” • Via Zinelibraries
- 20. Ethics • Choosing tools: • Omeka CMS vs Mukurtu CMS • Collecting data: • Boston College Oral Histories

Editor's Notes
- RAFIA
- Data are anything which is used or created to generate new knowledge and interpretations. “Anything” may be objective or subjective; physical or emotional; persistent or ephemeral; personal or public; explicit or tactic; and is consciously or unconsciously referenced by the researcher at some point during the course of their research. Research data may or may not lead to a research output, which regardless of method of presentation, is a planned public statement of new knowledge or interpretation. Garrett, 2012)
- Involves knowledge of quantitative (statistical) methods, metadata standards, and the data curation lifecycle. But also the understanding of
- Identifying problems that a dataset can answer
- Recognizing research potential of an existing heritage collection, or identifying ways to answer questions or problems. Develop a hypothesis based on the data. Becoming aware of the data features that enable new quantitative methods (including access, format, systematicity, and metadata) Understanding the context and provenience of a collection (including extension, representativeness, openness, and copyright and privacy issues)
- As the materials and analytical practices of research become increasingly digital, the theoretical knowledge and practical skills of information science, librarianship, and archival science will become ever more vital to humanists and to anyone working with cultural heritage.”
- Heritage collections
- “Another important distinction is between data and metadata. Here, the term “data” refers to the part of a file or dataset which contains the actual representation of an object of inquiry, while the term “metadata” refers to data about that data: metadata explicitly describes selected aspects of a dataset, such as the time of its creation, or the way it was collected, or what entity external to the dataset it is supposed to represent. Read papers and study accompanying documentation
- Need to know your data. What is the background of the person, time period, or language you are studying? What elements are represented and how were they obtained? What elements are missing or misrepresented? What are other questions you can ask or ways you can find out answers?
- How does this reflect itself in writing? How does one show their background? How does one signify?
- The present moment is filled with DH practitioners creating visualizations of ‘big data,’ mapping connections between people and ancient cities, and building archives dedicated to long-dead authors. These worthwhile academic and practical pursuits point us to the center of the digital humanities landscape. But, if we move to the margins and begin to look at the projects and tools that emerge from indigenous communities, archivists and cultural specialists, we see a different pattern: images are purposely removed, archives are not ‘open to the public,’ maps of sacred sites are consciously not created, defined or linked to. How do we integrate these varied practices and philosophies into the possibilities offered by digital humanities scholars? It is one thing to call attention to difference, it is another to alter our display practices, question access parameters, and redefine our own ways of knowing based on systems of accountability that define an ethical field of visually based on not looking. If seeing is believing and a picture is worth a thousand words, what can we learn from the act of not looking, or perhaps, more specifically, not seeing?

- More often than not, it is not the writer that is twisting the numbers but the numbers themselves twisting up the writer. Manipulation of the facts or of the reader is usually not intentional.

- Estimations from the Syrian Observatory for Human Rights. Imagine the decision that might have to be made to categorize a typical citizen with no military training, who has picked up a gun shortly before his death. Perhaps the coder might have a bias to continue calling this person a civilian. But this person took up arms against the government, did they not? How would you code a Syrian army defector now fighting with an opposition group? … Without some sort of standard protocol, rigorously followed, the coding of affiliation allows for a degree of subjectivity
- Talk to subject experts, read papers, and study accompanying documentation
- What is a numerical way to describe data?
- Frequency – how often a value exists (e.g., a name or gender) 50 women, 38 men, 2 other, 10 unknown Rank from lowest to highest – list albums’ use of personal pronouns in order of high to low Average - Measure of central tendency Variability – how different or similar scores are to each other (range, standard deviation)
- Contingency table, a type of summary table. This shows frequency distribution.

- HathiTrust: More than 2 million volumes are in the public domain and freely viewable on the Web.

- Data literacy is important so that we can • Tell compelling stories that others are more likely to repeat, remember, and act on • Determine when someone else is trying to mislead using visualizations
- Clean- open refine
- Identifier Independent information / fixed variables Dependent variables / measured variables
- This is similar to when you got that mosquito bite and were sure you were getting Zika Virus or West Nile, only to realize your arm itched for 24 hours.
- Business insider published using the chart but sought permission to reverse it, keeping the same design but turning it upside down for their readers.
- It’s true though, that images such as the visualisation above draw attention to some important issues. Though they state their data source (the Syria Network for Human Rights) what we’ve explored here so far makes it clear that this data has flaws. We can’t know for sure the extent of those flaws, though, and some might argue that as long as the main message is transmitted, the details don’t matter so much.
