We are delighted to announce that Anthony Jameson will give a keynote at our workshop:
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.
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.
