Jose School of Computing Science School of Computing Science University of Glasgow University of Glasgow Glasgow, UK Glasgow, UK yashar@dcs.gla.ac.uk Joemon.Jose@glasgow.ac.uk In this paper, we argue that standard and dominant view doesn’t sufficiently consider all the possible aspects of search- ers’ needs. Information Science (IS) researchers have argued ABSTRACT about the existence of needs other than IN, and discussed The main objective of Information Retrieval (IR) systems their roles in the cognitive aspects of human beings and in is to satisfy searchers’ needs.

However, these previous studies do role of emotion is limited to its relation with cognition in not give a sufficiently prominent position to emotion in IR, the process of satisfying an IN in an IR&S behaviour, e.g., since they limit the role of emotion to a secondary factor, Kuhlthau’s [3] model. Therefore, emotion plays a marginal by assuming that a lack of knowledge (the need for informa- role in these views in their modelling of needs.

The study conducted by Elsweiler et al. [2] also supported this claim. The current views of emotion in IR/IS do not sufficiently explain these types of activities accurately, even though it is clear that users search for emotionally-rich doc- uments from the Internet to satisfy these needs. The pervasiveness of emotionally-rich content on the web, such as movies, music, images, news, blogs, customer re- view, Facebook comments and Twitter, highlights the de- Presented at Searching4Fun workshop at ECIR2012.
