Genuine Information Needs of Social Scientists Looking for Data

Publishing research data is widely expected to increase its reuse and to inspire new research. In the social sciences, data from surveys, interviews, polls, and statistics are primary resources for research. There is a long tradition to collect and offer research data in data archives and online repositories. Researchers use these systems to identify data relevant to their research. However, especially in data search, users' complex information needs seem to collide with the capabilities of data search systems. The search capabilities, in turn, depend to a high degree upon the metadata schemes used to describe the data. In this research, we conducted an online survey with 72 social science researchers who expressed their individual information needs for research data like they would do when asking a colleague for help. We analyzed these information needs and attributed their different components to the categories: topic, metadata, and intention. We compared these categories and their content to existing metadata models of research data and the search and filter opportunities offered in existing data search systems. We found a mismatch between what users have as a requirement for their data and what is offered on metadata level and search system possibilities.

Data Discovery using LLMs -- A Study of Data User Behaviour

Data search for scientific research is more complex than a simple web search. The emergence of large language models (LLMs) and their applicability for scientific tasks offers new opportunities for researchers who are looking for data, e.g., to freely express their data needs instead of fitting them into restrictions of data catalogues and portals. However, this also creates uncertainty about whether LLMs are suitable for this task. To answer this question, we conducted a user study with 32 researchers. We qualitatively and quantitively analysed participants' information interaction behaviour while searching for data using LLMs in two data search tasks, one in which we prompted the LLM to behave as a persona. We found that participants interact with LLMs in natural language, but LLMs remain a tool for them rather than an equal conversational partner. This changes slightly when the LLM is prompted to behave as a persona, but the prompting only affects participants' user experience when they are already experienced in LLM use.

Supporting data discovery: A meta-synthesis comparing perspectives of support specialists and researchers

Purpose: Data discovery practices currently tend to be studied from the perspective of researchers or the perspective of support specialists. This separation is problematic, as it becomes easy for support specialists to build infrastructures and services based on perceptions of researchers' practices, rather than the practices themselves. This paper brings together and analyzes both perspectives to support the building of effective infrastructures and services for data discovery. Methods: This is a meta-synthesis of work the authors have conducted over the last six years investigating the data discovery practices of researchers from different disciplines, with a focus on the social sciences, and support specialists. We bring together and re-analyze data collected from in-depth interview studies with 6 support specialists in the field of social science in Germany, with 21 social scientists in Singapore, an interview with 10 researchers and 3 support specialists from multiple disciplines, a global survey with 1630 researchers and 47 support specialists from multiple disciplines, an observational study with 12 researchers from the field of social science and a use case analysis of 25 support specialists from multiple disciplines. Results: We found that there are many similarities in what researchers and support specialists want and think about data discovery, both in social sciences and in other disciplines. There are, however, some differences which we have identified, most notably the interconnection of data discovery with web search, literature search and social networks. Conclusion: We conclude by proposing recommendations for how different types of support work can address these points of difference to better support researchers' data discovery practices.
