Abstract
A visual term discrimination value analysis method is introduced using a do cument density space within a distance-angle-based visual information retri eval environment. The term discrimination capacity is analyzed using the co mparison of the distance and angle-based visual representations with and wi thout a specified term, thereby allowing the user to see the impact of the term on individual documents within the density space. Next, the concept of a "term density space" is introduced for term discrimination analysis. Usi ng this concept, a term discrimination capacity for distinguishing one term from others in the space can also be visualized within the visual space, A pplications of these methods facilitate more effective assignment of term w eights to index terms within documents and may assist searchers in the sele ction of search terms.
