"Modelling Information Seeking Strategies and Resources"
Staff and fundingPrincipal investigator: Prof Alistair Sutcliffe (Now at UMIST)

The MISSAR project investigated three HCI aspects of information retrieval:
Cognitive modelling of the information retrieval task - Experimental investigations of information seeking were assimilated with the information retrieval literature to evolve a high level task model of expert searching. The model was then used to develop rules for the provision of system initiated user-guidance during searching.
Query articulation structures - Empirical investigations into the information needs from three user populations (University Students, Journalists and Hospital Medical Staff) led to the development of query template structures to match population need profiles, and the development of an experimental system for the recognition of causal propositions in text.
Results visualisation - The task domain of journalists was the focus for the design of a graphical presentation of search results (NewsLine). The design exploited existing ideas of the representation of abstract information spaces, and used intersecting time lines to present search results in the form of an historical overview.
