We report on our ongoing study of using the genre of Web pages to facilitate information exploration. By genre, we mean socially recognized regularities of form and purpose in documents (e.g., a letter, a memo, a research paper). Our study had three phases. First, through a user study, we identified genres which most/least frequently meet searchers'(More)
This paper reports on one of the findings of a larger case study that attempts to describe how people organize documents in their own offices. In that study, several dimensions along which people make classificatory decisions were identified. Of these, the use to which a document is put emerged as a strong determiner of that document's classification. The(More)
THELINK BETWEEN CLASSIFICATION AND KNOWLEDGE is explored. Classification schemes have properties that enable the representation of entities and relationships in structures that reflect knowledge of the domain being classified. The strengths and limitations of four classificatory approaches are described in terms of their ability to reflect, discover, and(More)
People recognize and use document genres as a way of identifying useful information and of participating in mutually understood communicative acts. Crowston and Kwasnik [1] discuss the possibility of improving information access in large digital collections through the identification and use of document genre metadata. They draw on the definition of genre(More)
We discuss the issues of resolving the information-retrieval problem in large digital collections through the identification and use of document genres. Explicit identification of genre seems particularly important for such collections because any search usually retrieves documents with a diversity of genres that are undifferentiated by obvious clues as to(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. Data on browsing is collected from thirty participants-ten each in three browsing formats: print, command-driven computer(More)
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)
This paper reviews the current state of HCI. We argue that HCI lacks a suucient understanding of the issues that eeect the usability both of computer systems, and of HCI practices in real situations of system design and implementation. In this paper, we explore these issues from the perspective of`problem ownership'. Internally, various constituencies of(More)
