Describes research using an artificial intelligence approach in the application of a Kohonen Self-Organizing Map (SOM) to the problem of classification of electronic brainstorming output and an evaluation of the results. The graphical representation of textual data produced by the Kohonen SOM suggests many opportunities for improving information…

Uses a simple model of an information retrieval (IR) technology to examine performance measures for IR systems. Shows that, if a user is employing a system optimally, then reasonable performance measures will tend to be relatively robust, or insensitive, to small variations in assumptions about the user's behavior.
