From Exploration to Construction - How to Support the Complex Dynamics of In...TimelessFuture
Search engines on the Web provide a world of information at our fingertips, and the answers to many of our common questions are just one click away. However, for the complex and multifaceted tasks involving a process of knowledge construction, various information seeking models describe an intricate set of cognitive stages (Kuhlthau, 2004; Vakkari, 2001). These stages influence the interplay of users’ feelings, thoughts and actions. Despite the evidence of the models, common search engines, nowadays the prime intermediaries between information and user, still feature a streamlined set of 'ten blue links'. While efficient for lookup tasks, this approach may not be beneficial for supporting sustained information-intensive tasks and knowledge construction. Would there be other approaches to support the complex dynamics of these ventures? Based on previous experiments, this talk discusses how the utility of search functionality during different stages of complex tasks is essentially dynamic. This provides opportunities for designing 'stage-aware' search systems, which may evolve along with a user's information journey.

Discovering Common Motifs in Cursor Movement DataYandex
Mouse cursor movements can provide valuable information on how users interact and engage with web documents. This interaction data is far richer than traditional click data, and can be used to improve evaluation and presentation of web information systems. Unfortunately, the diversity and complexity inherent in this interaction data make it more difficult to capture salient behavior characteristics through traditional feature engineering. To address this problem, we introduce a novel approach of automatically discovering frequent subsequences, or motifs, in mouse cursor movement data. In order to scale our approach to realistic datasets, we introduce novel optimizations for motif discovery, specifically designed for mining cursor movement data. We show that by encoding the motifs discovered from thousands of real web search sessions as features, enables significant improvements in important web search tasks. These results, complemented with visualization and qualitative analysis, demonstrate that our approach is able to automatically capture key characteristics of mouse cursor movement behavior, providing a valuable new tool for online user behavior analysis. In addition to the application of motifs to web mining, we demonstrate that similar technique can be successfully applied in medical domain for the task of predicting future decline of memory function and subsequent development of the Alzheimer Disease.

Impact your Library UX with Contextual InquiryRachel Vacek
A contextual inquiry is a research study that involves in-depth interviews where users walk through common tasks in the physical environment in which they typically perform them. It can be used to better understand the intents and motivations behind user behavior. In this session, learn what’s needed to conduct a contextual inquiry and how to analyze the ethnographic data once collected. I'll cover how to synthesize and visualize your findings as sequence models and affinity diagrams that directly inform the development of personas and common task flows. Finally, learn how this process can help guide your design and content strategy efforts while constructing a rich picture of the user experience.

Data Visualization via Enhanced Maps in a Digital Humanities Context – a Desi...TimelessFuture
Long paper presentation at Digital Humanities Benelux 2024.
Abstract: In the past decades, geographical maps have been used extensively as a means for spatial data visualization in the Humanities and beyond. Here, we consider data visualization to be the “representation and presentation of data to facilitate understanding” (Kirk, 2019). While maps have myriad advantages for visualization, such as presenting the spatial distribution of data to potentially generate new insights, they are also are inherently abstractions of reality. This abstraction can raise issues (see e.g. Allen & Queen, 2015; Pavlovskaya, 2016), particularly in the context of complex and multifaceted historical datasets involving uncertainty. This paper conceptually discusses these issues from a design perspective in the context of DH, specifically looking at cartographic design, interaction design and data structure. Subsequently, it briefly reveals how these angles were addressed in an enhanced 2D geographical maps viewer created within the Virtual Interiors project (2018-2022), which displays spatio-temporal historical datasets.

This presentation at DH Benelux 2019, receiving one of the two best paper awards, includes findings of the ReVI project. This was a pilot looking at enhancing the Resource Viewer of the CLARIAH Media Suite, where audiovisual materials can be played. Specifically, the ReVI project looked at optimal ways "to support the exploration of different types of content metadata of audiovisual sources, such as segment information or automatic transcripts." During the project, various design thinking sessions were conducted, and a prototype including temporal content visualizations of audiovisual materials was created and evaluated in a user study. The findings of the user study showed a clear value of temporal visualizations and advanced annotation features for research purposes, as well as the continued importance of a data and tool criticism approach. New content exploration tools can benefit scholars doing research with audiovisual sources, for instance in media studies, oral history, film studies, and other disciplines which are increasingly using audiovisual media. The findings documented in the DH Benelux 2019 paper may serve as an inspiration for improving AV-media-based research tools. Concretely, it will also inform the further enhancement of the Resource Viewer of the CLARIAH Media Suite.

Presentation given at the CHIIR 2019 Workshop on Barriers to Interactive IR Resources Re-use (Glasgow, UK, March 14, 2019).
This experience paper shines more light on a simulated work task approach to studying information seeking stages. This explicit multi-stage approach was first utilized in a CHIIIR 2016 paper to investigate the utility of search user interface (SUI) features at different macro-level stages of complex tasks. We focus on the paper’s terminology, research design, methodology anduse of previous resources. Finally, based on our experience, we reflect on the potential for re-using our multistage approach and on general barriers to re-use in an Interactive Information Retrieval research context.

Towards Multidimensional Web Archive Access (IIPC 2016)TimelessFuture
Presentation at IIPC 2016 conference, Reykjavik, Iceland, 14 April 2016. Abstract:
Web archiving institutions have jointly harvested Petabytes of archived web content, in potential an exceptionally rich data source for researchers across the globe. These web archives are multidimensional by nature. First, a temporal dimension arises from different versions of web content accumulated over time. Second, a hierarchical dimension is implied as web archives may be examined at different analytical levels (Brügger, 2010), examples include the level of the web sphere, website and web page.
Scholars often focus their analysis on a specific analytical level and temporal range, for example looking at electoral web spheres at election times (Xenos and Bennet, 2007) or hyperlinking in news websites across time (Karlsson et al, 2015). However, we claim that this scholarly practice is not well supported by current web archive access tools, that usually allow only access at the page level and do not offer insights into the temporal development of broader selections of archived Web content, such as web spheres or websites. Hence, there is a need for more flexible access services in a research context.
In this presentation, we conceptually and practically explore how to address this mismatch. We illustrate how the temporal dimension can be harnessed by aggregating web content using different time ranges and the hierarchical dimension accommodated by novel aggregation support. Utilizing a concrete use case, we illustrate the potential usefulness of these representations of aggregated Web content. We analyze and compare the temporal evolution of various categories of websites in the Dutch Web Archive (such as news, history-related and government websites) across a five-year period. In this analysis, we look at the evolution of textual content, internal structure and image content across categories and websites. Finally, our presentation indicates how these types of aggregated representations may be integrated into future search systems for Web archives.

3. multistage interface
• Third option: differentiating search stage sensitive features &
offer customized SUI support for stages in complex search
!
• by adaptively showing SUI features
• by adjusting shown details of features
• by changing prominence, position and size of features, …
30. 5. Future work
• Integrating this approach into
the user’s flow
• without being intrusive or confusing
!
• Ways to support evolving
stages, e.g.
• on the interface level (SUI feature
