Although computational tools play an increasingly important role in the humanities, adoption of tools by scholars does not always reach its potential. One approach to this problem is user research to uncover the needs of the users. However, it is uncertain whether such user requirements can be generalized to a wider group of humanities scholars, and whether users are able to explicate their requirements for methodological innovation. We ask what the role of user research is in the Digital Humanities by discussing gathered user requirements for two projects. We categorized the requirements as within- or out-of-scope of the projects’ goals, and found a tension between the specificity of humanities’ research methods, and generalizability for a broader applicable tool. With the out-of-scope requirements we are able to map the wider research workflow, showing DH tools will most likely take a spot in the wider workflow, and that it is infeasible to create a tool for the entire workflow that is generic enough for a larger user group. However, the within-scope requirements led to features that were sufficiently generic for the tool to be adopted, also for unintended purposes. These insights show user research has a clear benefit for DH projects. [less ▲]

Students and researchers of media and communication sciences study the role of media in our society. They frequently search through media archives to manually select items that cover a certain event. When this is done for large time spans and across media-outlets, this task can however be challenging and laborious. Therefore, up until now the focus of researchers has been on manual and qualitative analyses of newspaper coverage. PoliMedia aims to stimulate and facilitate large-scale, cross-media analysis of the coverage of political events. We focus on the meetings of the Dutch parliament, and provide automatically generated links between the transcripts of those meetings, newspaper articles, including their original lay-out on the page, and radio bulletins. Via the portal at www.polimedia.nl researchers can search through the debates and find related media coverage in two media- outlets, facilitating a more efficient search process and qualitative analyses of the media coverage. Furthermore, the generated links are available via a SPARQL endpoint at data.polimedia.nl allowing quantitative analyses with complex, structured queries that are not covered by the search functionality of the portal, thus challenging the student to go across the academic borders and enter fields that previously have been neglected.

AXES, Access for Audiovisual Archives, is a research project developing tools for new engaging ways to interact with audiovisual libraries, integrating advanced audio and video analysis technologies. The presented prototype is targeted at academic researchers and journalists. The tool allows them to search and retrieve video segments through metadata, audio analysis, as well as visual concepts and similarity searches. Presented here is a user-based vision on the research-oriented tool provided by AXES. [less ▲]

The transition from analogue to digital archives and the recent explosion of online content offers researchers novel ways of engaging with data. The crucial question for ensuring a balance between the supply and demand-side of data is whether this trend connects to existing scholarly practices and to the average search skills of researchers. To gain insight into this process we conducted a survey among nearly three hundred (N= 288) humanities scholars in the Netherlands and Belgium with the aim of finding answers to the following questions: 1) To what extent are digital databases and archives used? 2) What are the preferences in search functionalities 3) Are there differences in search strategies between novices and experts of information retrieval? Our results show that while scholars actively engage in research online they mainly search for text and images. General search systems such as Google and JSTOR are predominant, while large-scale collections such as Europeana are rarely consulted. Searching with keywords is the dominant search strategy and advanced search options are rarely used. When comparing novice and more experienced searchers, the first tend to have a more narrow selection of search engines, and mostly use keywords. Our overall findings indicate that Google is the key player among available search engines. This dominant use illustrates the paradoxical attitude of scholars toward Google: while provenance and context are deemed key academic requirements, the workings of the Google algorithm remain unclear. We conclude that Google introduces a black box into digital scholarly practices, indicating scholars will become increasingly dependent on such black boxed algorithms. This calls for a reconsideration of the academic principles of provenance and context. [less ▲]

Facets can provide an interesting functionality in digital libraries. However, while some research shows facets are important, other research found facets are only moderately used. Therefore, in this exploratory study we com- pare two search interfaces; one where the facets panel is always visible and one where the facets panel is hidden by default. Our main research question is “Is folding the facets panel in a digital library search interface beneficial to aca- demic users?” By performing an eye tracking study with N=24, we measured search efficiency, distribution of attention and user satisfaction. We found no significant differences in the eye tracking data nor in usability feedback and conclude that collapsing facets is neither beneficial nor detrimental. [less ▲]

Analysing media coverage across several types of media-outlets is a challenging task for academic researchers. The PoliMedia project aimed to showcase the potential of cross-media analysis by linking the digitised tran- scriptions of the debates at the Dutch Parliament (Dutch Hansard) with three media-outlets: 1) newspapers in their original layout of the historical newspaper archive at the National Library, 2) radio bulletins of the Dutch National Press Agency (ANP) and 3) newscasts and current affairs programs from the Netherlands Institute for Sound and Vision. In this paper we describe generally how these links were created and we introduce the PoliMedia search user interface developed for scholars to navigate the links. In evaluation it was found that the linking algorithm had a recall of 67 and precision of 75\%. Moreover, in an eye tracking evaluation we found that the interface enabled scholars to perform known-item and exploratory searches for qualitative analysis. [less ▲]

With an ever-growing supply of online sources, information to produce news sto- ries seems to be one mouse click away. But in what way do Dutch journalists actual- ly use computer-aided research tools? This article provides an inventory of the ways journalists use digital (re)sources and explores the differences between experts and novices. We applied a combined methodological approach by conducting an ethno- graphic study as well as a survey. Results show that Dutch journalists use relatively few digital tools to find online information. However, journalists who can be conside- red experts in the field of information retrieval use a wider range of search engines and techniques, arrive quicker at the angle to their story, and are better at finding information related to this angle. This allows them to spend more time on writing their news story. Novices are more dependent on the information provided by others. [less ▲]

Formulating requirements for a video search system can be a challenging task when everyone is a possible user. This paper explores the possibilities of classifying users by creating a Profile Matrix, placing users on two axes: experience and goal-directedness. This enables us to describe the characteristics of the subgroups and investigate differences between the different groups. We created Profile Matrices by classifying 850 respondents of a survey regarding a requirements study for a video search system. We conclude that the Profile Matrix indeed enables us to classify subgroups of users and describe their characteristics. The current research is limited to descriptions of subgroups and analysis of differences between these subgroups. In the future, we want to research what these differences mean with regard to the users’ performance and acceptance of a video search system and explore the use of a profile matrix for other types of search systems.
