Data scopes describe the process of data gathering, cleaning and combining in digital humanities research, which is too often considered as mere preparation that is not part of research, and is mostly not described in scholarly communications. We argue that scholars need to be more aware of the intellectual effort of this process and make it more transparent
A hands-on approach to digital tool criticism: Tools for (self-)reflectionMarijn Koolen
Digital tool criticism is a recent and important discussion in Digital Humanities research. We define digital tool criticism as the reflection on the role of digital tools in the research methodology and the evaluation of the suitability of a given digital tool for a specific research goal. The aim is to understand the impact of any limitation of the tool on the specific goal, not to improve a tool’s performance. That is, ensuring as a scholar to be aware of the impact of a tool on research design, methods, interpretations and outcomes. Our goal with developing digital tool criticism as a method is to help scholars better understand how research methods, tools and activities shape our interpretations. Based on our experiences with two hands-on workshops on digital tool criticism, we find that reflection on using digital tools and data in all phases of the research process is key.
Reflection urges scholars to consider digital data and tools as part of the overall research goals and design, and interdependent with other elements of research design, namely research questions and methods. As scholars go through their research process, assumptions on the research design and the connection between tools, data and questions are constantly challenged, forcing updates in the design and the interpretation of data and question.

Website User Experience: A cross-cultural study of the relation between user...Ather Nawaz
Increasing globalization and technological development has led companies and people across the globe to connect through the global internet community. However, people with different cultural backgrounds may perceive the same information in different ways. One of the hurdles to use websites efficiently is the indifferent structures of information on website, and their relation with the characteristics of intended users and the context of use for the websites. The purpose of this dissertation is to assist Human-Computer Interaction (HCI) practitioners and researchers with better design of website structures for user groups with different cultural backgrounds.
This dissertation looks into issues related to website user experience (UX) and focus on how the structuring of information is seen from local users’ perspectives. In particular, it attempts to look into the alignment between websites’ information architecture (IA) and users’ views of website information structure, by applying a cross-cultural and context of use perspective on the UX of websites in three countries: Pakistan, Malaysia, and Denmark. The researcher investigates to what degree users’ cognitive styles and contexts of use are aligned with local websites’ information architecture, and how this (lack of) alignment shapes the resulting UX.
This dissertation adopts a mixed-method approach to studying the UX association with users’ cognitive styles, contexts of use, and website structures. In this regard a critical literature review of the existing HCI research on website UX in Asia was performed. Four UX studies were conducted on local university websites in Denmark and Pakistan, and local e-commerce websites in Pakistan and Malaysia. Empirical data was collected through questionnaires, card-based brainstorming, card sorting, information retrieval tasks, and retrospective interviews with 108 university students across four studies. Users’ cognitive styles were captured through users´ information classification (card sorting) activities with website contents. These data were analyzed through edit distance measures and hierarchical clustering through dendrograms. The context of use was captured by collecting data on domains of websites, interviews about the use of languages, background questionnaires, and information retrieval tasks. These data were analyzed through quantitative analysis and coding of retrospective interviews. The structures of the websites were captured through analysis of website navigation and labels employed by each website.
The literature review revealed that HCI research into website UX in Asia is growing, in particular examining academic, e-commerce websites, and tourism websites. The literature review indicated that the use of cultural theories and frameworks for studying website UX is limited. The results of the four UX studies indicated differences in cognitive style and context of use across the three locations, Denmark, Pakistan, and

The field of learning analytics (LA) is working on the definition of frameworks that structure the legal and ethical issues that stakeholders have to take into account regarding LA solutions. While current efforts in this direction focus on institutional and development aspects, this paper reflects on small-scale classroom oriented approaches that aim at supporting teachers in their practice. This reflection is based on three studies where we applied our teacher-led learning analytics approach in higher education and primary school contexts. We describe the ethical issues that emerged in these learning scenarios, and discuss them according to three dimensions: the overall learning analytics approach, the particular solution to learning analytics adopted, and the educational contexts where the analytics are applied.

The Humanities Cluster invests a lot of effort in developing infrastructure and tools for digital research. As scholars we want those tools to be easy to use and don't want to bother with many of the technical details. But their ease of use often makes it hard to check if there is a devil in those details who we should want to meet. Digital tools can do a lot of work for us, but only because they are based on a lot of assumptions. Which of these assumptions are important to consider in research? And how can we develop infrastructure and tools that wear their assumptions on their sleeves and that invite us to reflect on their impact? In this talk I will present our research in attempting to address these questions. We have developed conceptual frameworks and techniques for digital tool criticism and evaluation and for thinking and communicating about digital data processes in research. I will discuss the lessons we have learned from bringing these frameworks and techniques into practice and how we can incorporate these lessons in digital humanities research methodology and in developing digital infrastructure.
1:1 Community Interview Examples & Tips for LibrariesWiLS
Presented at WLA 2021 Annual Conference, November 19th, by Laura Damon-Moore, WiLS; Martín Alvarado, Madison Public Library; Jon Mark Bolthouse, Fond du Lac Public Library
In this session, attendees will hear about three different case studies for using 1:1 interviews as an information gathering method in a library or other municipal setting: 1) to learn how people currently use a city service and how that service might evolve to better suit community needs; 2) to learn about the wider community’s and individuals’ goals and aspirations, and challenges they see or experience in order to inform a library’s planning process; 3) to tell a more complete story of a community’s history through 1:1 interviews. Along with these case studies, session organizers will offer some best practices and practical tips for conducting 1:1 interviews to support these similar yet distinct information gathering efforts.

This paper examines the digital skill level of refugee migrants in Germany while pursuing a job, a training position, or following an educational path on the Internet. For that, we conducted a lab experiment designing tasks with varying difficulty to position the digital competencies of refugee migrants on the digital skill scale. Problems with operational and formal skills were observed whereas fact-based information seeking was often successfully completed. The most complex tasks could not be completed by any participant. The study contributes to a better understanding of the varying degrees of digital skills of refugee migrants. Results can be used to design targeted courses and curricula that address digital deficits. Further training in this area will enable refugee migrants to benefit from the many opportunities that arise through the Internet and its services, improving their chances for labor market integration.

Barcamps are conferences without predened content, often referred to as ad-hoc conferences or unconferences. Therefore, the outcomes of a barcamp are largely unknown before the event. This raises the question of participants' motivations to attend and contribute. To answer this question, we conducted an exploratory empirical study at the Barcamp Graz 2012. We applied a mixed-method approach: First we used a sociodemographic questionnaire (n=99) which allowed us to characterize the 'typical barcamper'. Second, we conducted qualitative interviews (n=10) to get a deeper
understanding of the participants' motivations to attend, expectations and the use of social media in that context. We identied three concepts, which could be deducted from the interviews: people, format and topics. We found that the motivation to attend and even a common identity is quite strongly based on these three factors. Furthermore, the results indicate that participants share a set of activities and methods by following the barcamp's inherent rules and make extensive use of social media.

Introduction
In life, there are universal laws that govern everything we do. These laws are so perfect that if you were to align yourself with them, you could have so much prosperity that it would be coming out of your ears. This is because God created the universe in the image and likeness of him. It is failure to follow the universal laws that causes one to fail. The laws that were created consisted of the following: ·
Law of Gratitude: The Law of Gratitude states that you must show gratitude for what you have. By having gratitude, you speed your growth and success faster than you normally would. This is because if you appreciate the things you have, even if they are small things, you are open to receiving more.
Law of Attraction: The Law of Attraction states that if you focus your attention on something long enough you will get it. It all starts in the mind. You think of something and when you think of it, you manifest that in your life. This could be a mental picture of a check or actual cash, but you think about it with an image.
Law of Karma: the Law of Karma states that if you go out and do something bad, it will come back to you with something bad. If you do well for others, good things happen to you. The principle here is to know you can create good or bad through your actions. There will always be an effect no matter what.
Law of Love: the Law of Love states that love is more than emotion or feeling; it is energy. It has substance and can be felt. Love is also considered acceptance of oneself or others. This means that no matter what you do in life if you do not approach or leave the situation out of love, it won't work.
Law of Allowing: The Law of Allowing states that for us to get what we want, we must be receptive to it. We can't merely say to the Universe that we want something if we don't allow ourselves to receive it. This will defeat our purpose for wanting it in the first place.
Law of Vibration: the Law of Vibration states that if you wish on something and use your thoughts to visualize it, you are halfway there to get it. To complete the cycle you must use the Law of Vibration to feel part of what you want. Do this and you'll have anything you want in life.
For everything to function properly there has to be structure. Without structure, our world, or universe, would be in utter chaos. Successful people understand universal laws and apply them daily. They may not acknowledge that to you, but they do follow the laws. There is a higher power and this higher power controls the universe and what we get out of it. People who know this, but wish to direct their own lives, follow the reasons. Successful people don't sit around and say "I'll try," they say yes and act on it.

Understanding Understanding: Implementing Design-Focused Service Initiatives ...Joe Marquez
Inspired by the inaugural D4D 2015 conference, librarians from Reed College and Montana State University have kept in touch to brainstorm and share ideas on design research and service design. Our projects have many parallels, yet remain unique due to our distinct work environments and goals for our respective projects. We share a common belief that the holistic approaches of design research are critically important for creating and sustaining library services.
Design research and its holistic blending of the physical and digital is the next important topic for libraries. It holds great power for improving library services, but initiating and planning a project of this type comes with a unique set of challenges, including gaining buy-in; working out logistics, timing, and scope; and appropriately matching methods to research questions. This 90 minute presentation/session will start with a discussion of the different types of design and will provide attendees with points of conversation they can adapt to help build a shared understanding with colleagues and administrators of the value of design research. We will then discuss how we got started at our individual libraries and offer advice and resources for getting traction on and sustaining projects. Following the presentation section of our session, we will work through a set of exercises to help attendees practice design-focused research techniques.

News recommenders have the potential to help users filter the enormous amount of news that is available online, and as such may play an important role in determining what information users do and do not get to see. However, current approaches to evaluating recommender systems are often focused on measuring an increase in user clicks and short-term engagement, rather than measuring the user's and society’s longer term interest in diverse and important recommendations. In this talk we aim to bridge the gap between so-called normative notions of news diversity, as it is known in social sciences and specifically democratic theory, and quantitative metrics necessary for evaluating the recommender system. We discuss a number of democratic missions a recommender system could have, together with a set of evaluation metrics stemming from these missions, and suggest ways for practical implementations of these metrics.
The talk will be about practical considerations that our team has had to make in order to bring a recommender system into production. I’ll cover the “default” tools with which we started (Batch processing in Spark) and follow that up with more recent tools like AWS Lambda and Spark Streaming.

Facilitating reusable third-party annotations in the digital editionMarijn Koolen
We argue the need for support of annotations on an edition made by researchers unaffiliated to the edition project, as a contribution to the explanatory material already present on the site, for purposes of private study or for publication in conjunction with a scholarly article. We demonstrate our annotation approach, that exploits RDFa for embedding the edition-specific semantics and identifier in the edition's HTML pages. We discuss an
FRBROO- based ontology of the editorial domain, capable of describing both the objects of editing (Text and Document) and their representation in the edition. We have a fully functional and open source prototype of an annotation tool that over the coming years will be actively developed, for use in multiple disciplines.
Narrative-Driven Recommendation for Casual Leisure NeedsMarijn Koolen
Recommender systems typically generate recommendations for a user based on their profile, or for an item given its user interactions, but there are many scenarios especially in leisure domains such as books, movies, games and music, where users have specific recommendation needs, where they want to steer the recommendation process towards certain aspects they find relevant. Currently, there are few recommender or search systems that can deal with the complexity of such directed needs, nor do we know well which data types (metadata, user ratings and reviews, item content) are useful to match against different aspects of recommendation needs. There are many discussion forums where users describe their needs and their frustration with current search and recommender systems. In this talk I will summarize our work on analyzing relevance aspects for these needs and describe experiments on dealing with these.
Scholary Web Annotation - HuC Live 2018Marijn Koolen
Web annotation has a lot of potential for scholarly research but current tools have several big limitations. At the Humanities Cluster of the Royal Netherlands Academy of Arts and Sciences we are developing a scholarly web annotation tool that allows different types of fine-grained annotations on objects of any media type and combining manual and algorithmic annotations.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Nucleophilic Addition of carbonyl compounds.pptxSSR02
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skills
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

Data Scopes
Towards transparent data research in digital humanities
3. ● Making data work for research requires:
○ Technical know-how of how digital tools handle data
○ Intimate knowledge of the domain and subject of source materials
● But also:
○ Reflection on how choices are informed by prior knowledge and experience
○ Reflection on how choices put emphasis on some aspects, while pushing back others
○ Reflection of the transformation of data in the research process
● Often requires collaboration…
○ How to organise that
● … and lots of discussion
○ Choices that one collaborator makes should be visible to the rest
Motivation
4. Data Scopes
● Coherent methods for using digital data in humanities research
● Data scope: you want to analyse a certain aspect of your materials,
○ but the “raw” data is not suitable for direct analysis.
● You have to do something with the data. Questions:
○ What do I have to do to make data suitable?
○ How do I do that?
○ What should I document of this process to I can share it with others?
○ Which parts of this process are specific to my analysis and which are generically applicable?
5. Example: discourse coalition migration
● Research question: what determined the discourse about the management of migrants
● Context: research project about Dutch emigration 1945-1992
● Sub questions:
○ Who were involved in the international discourse about the management of migrants
○ How did the discourse change over time
○ How can we relate these changes
○ Scientification of politics and the politization of science
● Different datasets:
○ About people and their relation
○ About the discourse

9. Focus on Data-Related Activities
Data Interactions
● It’s not about specific tools
○ It’s about the steps researchers take, why they take them
● Translate research questions, assumption and interpretations to data interactions
● Discuss the consequences of interactions for questions, assumptions and interpretations
Frameworks focusing on process
● Scholarly Primitives (Unsworth 2000): discover, annotate, compare, refer, sample, illustrate,
represent
● Stages of Data Visualization (Fry 2007): acquire, parse, filter, mine, represent, refine, interact
● Data Scope: select, model, normalise, link, classify
10. ● Research plan:
○ Analyse network of experts involved in discourse on migration
● Research process:
○ Translate plan into sequence of data selections and transformations
○ Cycle of interpretations, decisions and actions
● Research description (van Faassen & Hoekstra 2017):
○ “To find out exactly how these experts were connected to key actors from the political sphere,
[...], we went through the prefaces of the publications. We modelled the different roles of the
key actors based on issues such as: who were writing forewords, prefaces or introductions to
each other’s work; Who ordered the research? Who financed it? Etc.”
Creating a Data Scope
11. Selecting
● Which materials do I include? Which do I exclude and why?
○ How important are completeness, representativeness?
○ Potentially huge impact on network analysis
● Algorithmic selection:
○ Everything matching a (set of) keyword(s)
○ Documents by type, creator, title, size, …
○ How does technology allow and limit selection?
● What are consequences of these selections?
12.
13. ● Computational approach requires modelling data (McCarty 2004)
● Determine what aspects/elements of data to focus on and what to leave out (why?)
○ People and organizations involved in discourse coalition
i. Authors, editors, commissioners, sponsors
○ Change in coalitions from 1950s in 10 year periods
● Structures data in sources around research focus
○ Transforms data, affects interpretation!
Modelling
14.
15. ● Modelling data creates data axes:
○ Persons, organisations, locations, dates,
○ Themes, topics, events, actions, decisions, life courses, ...
● Defining categories or classes along those axes:
○ Roles of people and organisations, memberships
○ Periods, regions
● Research stages:
○ Model is updated as research progresses
○ This updating reflects growing insights
○ Choice points reflect shifts in interpretation
Data axes
16. Normalizing
● Bring surface forms expressed in data to underlying standard form
● Map variation onto a single representation:
○ Linguistic, geographical, spatial, temporal, structural
○ E.g. entrepreneur, entrepreneurs, entrepreneurship
○ Important consequences whenever you count frequencies or analyse networks
● What is irrelevant variation?
○ Is the distinction between entrepreneur, and entrepreneurship important for research focus?
○ Uncertainty: are mentions of New York and NYC variants that refer to the same thing?
● Essential for next step: linking
17. ● Establishing explicit connections between objects in data sources
○ Within a dataset: relations between people, organizations
○ Across datasets: e.g. mentions of same person, location, date, …
i. Can bring together disparate data about single entity from different sources
● What counts as a link?
○ Editor - Main author
○ Preface author - Main author
○ Commissioner - Main author
○ Commissioner - Sponsor
Linking
18. Classifying
● Reduction of complexity by grouping (data) objects into predefined categories, or classes
○ Bringing together objects with similar properties
○ Separating objects with dissimilar properties
● Adds new layers of structure and interpretation to data
○ Especially useful for low-frequency items
○ Many data dimensions have “long tails” which are hard to structure
● Deciding on classification dimensions and classes is part of modelling
20. ● Too often, scholars consider this process as “mere preparation”
○ “... not part of the real research”,
○ Leave it out of scholarly communication as it “gets in the way of the narrative”
● Process of selecting, modelling and transforming is intellectual effort
○ Requires both technical and domain knowledge and interpretation
○ Different choices can lead to very different analyses and interpretations
Conclusions (1/2)
21. Conclusions (1/2)
● Too often, scholars consider this process as “mere preparation”
○ “... not part of the real research”,
○ Leave it out of scholarly communication as it “gets in the way of the narrative”
● Process of selecting, modelling and transforming is intellectual effort
○ Requires both technical and domain knowledge and interpretation
○ Different choices can lead to very different analyses and interpretations
● Even if you didn’t consider a certain transformation you still made a
choice!
22. Conclusions (2/2)
● Need to increase shared understanding
○ Both in terminology and methodology
○ Data scope provides set of concepts to address this
● Open questions
○ How do we communicate data scope process to collaborators and peers?
○ Need for alternative forms of publication?
■ E.g. layered publication: narrative < process < data

25. Q&A
● Q: What is the difference between this process in digital context and in analog
context? In analogue research, we have always obfuscated certain parts of
the process. Why do we need more transparency now?
○ A: There is no difference. Transparency of process was as important then as it is now.
○ The issue is that there currently is a lack of shared understanding of and terminology for
talking about this process and how it fits in research methodology and practice.
○ The reason why we can leave out details of the analogue process is that practitioners have
been trained in these analogue methods, with a shared understanding of the steps involved
and pitfalls to avoid. In digital research, this is not yet the case.
○ We need to discuss how to communicate about this process to collaborators and peers, at
what level of detail of technical steps and choices and consequences. The most detailed level
is probably too detailed, obfuscating the more relevant aspects in a flood of trivial details.
○ Moreover, humanities researchers tend to use digital tools in their data research that transform
their data, but that are viewed as black boxes that ‘just do a job’. This makes it even more
urgent to document research in the digital era.
26. Q&A
● Q: Tracing this data transformation process is basically the issue of
provenance. To what extent can existing provenance tools tackle this?
○ A: Documenting steps that lead to research output captures only a part of the process, but
misses important parts.
○ First, existing tools keep tracks of steps but not of alternative choices, considerations and
reasoning for steps.
○ Second, such tools tend to suggest a linear flow from raw input to final output, which misses
the point that the research process is non-linear and leaves out the dead ends that can lead to
new insights and judgements.
27. Q&A
● Q: Are there existing solutions for dealing with the dynamics of the coalition
network for different periodizations? E.g. instead of having non-overlapping
periods, visualize the networks for 10 year periods with 1-year of 5-year
jumps? Would that solve the problem of interpreting these networks?
○ A: Communicating about the research process is important, regardless of the approach taken.
A sliding window of 10 periods shifting 1 year each step introduces new questions of
interpretation and potential consequences.
○ Note that using multiple, complementary analyses can provide complementary perspectives
and ways to reciprocally and critically assess the individual analyses.
