First, through a user study, we identified genres which most/least frequently meet searchers'(More)
The paper describes a descriptive study of the functional components of browsing, which is viewed as the strategic and adaptive technique that people use to search, scan, navigate through, skim, sample, and explore information systems.

We report on a project which attempts to classify representations of the anomalous states of knowledge (ASKs) of users of document retrieval systems on the basis of structural characteristics of the representations, and which specifies different retrieval strategies and ranking mechanisms for each ASK class. The classification and retrieval strategy(More)
