  • Personalized information management systems with tutorial capabilities

    Creator:
    Oman, Paul W.
    Abstract:
    Technological advances of the last three decades have caused an enormous increase in the amount of published and unpublished information generated by our society. This inflation has created the need for improved information management systems. Existing systems are inadequate primarily because they are discipline-oriented and lack the flexibility that is...

  • On feature relevance feedback methods : incorporating labeled user features

    Creator:
    Oberst, Ian
    Abstract:
    In text classification, labeling features is often less time consuming than labeling entire documents. In situations where very little labeled training data is available, feature relevance feedback has the potential to dramatically increase classification performance. We review previous work on incorporating feature relevance feedback in the form of labeled features...

  • SERF: integrating human recommendations with search

    Creator:
    Jung, Seikyung, Harris, Kevin, Webster, Janet G., and Herlocker, Jonathan L.
    Abstract:
    Today's university library has many digitally accessible resources, both indexes to content and considerable original content. Using off-the-shelf search technology provides a single point of access into library resources, but we have found that such full-text indexing technology is not entirely satisfactory for library searching. In response to this, we...

  • A dataflow mechanism for supporting query optimization

    Creator:
    Kalvin, Patricia M.
    Abstract:
    The objective of this thesis is to develop a tool which can be used to implement query processing algorithms produced by a query optimizer. The tool should have the following properties: (1) it should support a description of the query solution in a dataflow-like language, (2) it should support data...

  • Effectiveness of index size reduction techniques

    Creator:
    Jacobson, Bryan L.
    Abstract:
    Index size savings from three techniques are measured. The three techniques are: 1) eliminating common, low information words found in a "stop list" (such as: of, the, at, etc.), 2) truncating terms by eliminating word stems (such as: -s, -ed, -ing, etc.), and 3) simple data compression. Savings are measured...

  • Using provenance to aid document re-finding

    Creator:
    Lonsdale, Heather
    Abstract:
    In the field of Human-Computer Interaction, provenance refers to the complete history and genealogy of a document. Provenance can be useful in identifying related resources, such as different versions of the same document or resources used in the creation of a new document. Though methods of provenance collection and applications...

  • Annotation of image segments with ontologies (AISO)

    Creator:
    Lingutla Venkata, Nikhil Tej
    Abstract:
    This M.S thesis presents an interactive software tool that I have developed in the course of the past two years. This interactive tool is called AISO. AISO is aimed at interactive image segmentation and annotation tool designed to allow users to segment an image – such as those produced with...

  • Getting to the information you already have

    Oregon State University. Dept. of Computer Science, Rajaram, Vidya, Stumpf, Simone, Burnett, Margaret, 1949-, Dragunov, Anton, Wick, Evelyn, Lynn, Juliana, Johnsrude, Kevin, and Herlocker, Jonathan Lee
    Abstract:
    Knowledge workers need to find information but even when it is stored on their local computer systems, finding it can be costly. There are many researchers working on solutions to reduce these costs, but there has been little research into exactly what these costs are, and what the ties are...

  • SIDUR--a formalism for structuring knowledge bases

    Creator:
    Kogan, Dan D.
    Abstract:
    A new class of information intensive applications is emerging [Fuch82; Ohsu82] for which neither Artificial Intelligence (AI) nor Database technologies alone are well suited. Database systems do not provide the general inferential capabilities required for problem solving, while AI techniques have not been adapted to handle massive amounts of structured...
