Abstract: Behaviour with Search and Recommender Systems: what can it tell us?

Recommender Systems and IR are technically very similar problems, but are typically treated separately and often investigated by different groups of researchers. Looking at how people behave with such systems can be one way of unifying the problem, as well as the researchers, and can also be a useful, complementary evaluation method.  When examining user behaviour, context is crucial.  By focusing on the user behaviour and the encapsulating context, we can ask questions about tools that combine search and recsys like: when do people prefer to search and when do they prefer recommendations? What does this mean for what they are trying to achieve? In this talk I will try to answer such questions with examples from leisure and health domains. Finally, looking towards the future, I will argue that the relationship between search and recommender systems and behaviour can go full circle i.e., that both have the potential to impact on user behaviour in positive ways, and will present some ideas that I together with collaborators are doing to explore this.


David Elsweiler is a lecturer and post-doctoral researcher at the University of Regensburg, Germany. Before that he was an Alexander von Humboldt Research Fellow at the University of Erlangen-Nuremberg also in Germany.  David’s research focuses on understanding information behaviour with the main aim of designing information systems that align with the way people think and behave naturally. He received his Ph.D from the University of Strathclyde, United Kingdom in 2007. David has published 50 conference papers, journal articles and book chapters on personal information management, search and recommender systems, as well as user studies investigating what users want from such systems and how they behave to achieve their aims. David has won several awards including an ACM SIGIR Outstanding Paper Award (2011) and an Emerald Outstanding Author Contribution Award for best book chapter (2011).

This year he is general co-chair for the Information Interaction in Context Conference ( and he has previously co-organised successful workshops at ACM SIGIR, BCS, ECIR, CIKM, ASIST and CSCW on topics such as Desktop Search, Evaluation of Personal Search, Searching4Fun, Personal Information Management and Living-labs Evaluation.

Roles of Context in Information Retrieval and Recommendation: A Choice and Decision Making Perspective

Abstract: Systems for information retrieval and recommendation can be seen as tools that help people make good choices and decisions: about which documents to read, which products to buy, which people to contact, …. Taking this perspective, we can exploit insights from psychological research on how people make choices and decisions – in particular, on the role played by psychologically relevant contextual factors such as current goals, mood, time pressure, and distractions. In this talk, after looking at a compact overview of the diverse psychological processes involved in choosing – ranging from choices made quickly and intuitively to deliberate decisions – we will consider some questions about the roles of context in these processes: How can context influence a person’s current information need or the value that they attach to a particular item? How can context influence how such needs and evaluations are expressed or reflected in behavior (even if it doesn’t influence these things themselves)? And in the light of the answers to these questions: To what extent do people actually have needs and evaluations which exist independently of the contexts in which they are reflected in behavior? Implications for the design and study of context-aware systems for retrieval and recommendation will be discussed with audience participation.

Short Bio

Anthony Jameson is a principal researcher at DFKI, the German Research Center for Artificial Intelligence, where he heads the recently founded research unit on Choosability Engineering, which synthesizes and exploits knowledge about human choice and decision making in the design and study of (intelligent) interactive systems. Much of his research over the past three decades has addressed various aspects of user modeling and recommendation in interdisciplinary ways. He is the author of the chapter Choices and Decisions of Computer Users in the forthcoming third edition of the Human-Computer Interaction Handbook and founding coeditor-in-chief (with John Riedl) of the ACM Transactions on Interactive Intelligent Systems.
