User interface system and method for traversing a database

摘要

A user interface system and method for traversing a database. In one aspect the present invention includes providing a plurality of command options, each of the command options represented by a set of descriptive option index terms characterizing that command option. The set of descriptive option index terms characterizing the command options selected by a user, are compared with sets of document index terms. Each set of document index terms being compared characterizes an electronic document in a hypertext-type database which is selectively linked in that database with the user's present position. The comparisons result in a ranked list of the selectively linked electronic documents. The electronic documents are ranked in accordance with the relevancy of each document with respect to the selected command option. In another aspect of the invention, a plurality of command options are generated and displayed on a computer controlled display system (CCDS), each command option being represented by a portrayed character or personality associable to the user as being biased toward a particular type of information. Each of the command options represent a set of option index terms which characterize that particular command option. The set of option index terms characterizing the command option presently selected are compared with sets of document index terms. Each set of document index terms characterize an electronic document located within the database. The comparisons result in a ranked list of electronic documents, the documents being ranked in accordance with the particular bias of the portrayed character or personality.
