Widyantoro, Dwi H.; Ioerger, Thomas R.; Yen, John
Journal of the American Society for Information Science and Technology, v52 n3 p212-25 Feb 1, 2001
Describes a scheme to represent a user's interest categories in an environment like the Web, and an adaptive algorithm to learn the dynamics of the user's interests through positive and negative relevance feedback. Proposes a three-descriptor model to represent a user's interests. Empirical studies confirm the effectiveness of this scheme to accurately model a user's interest and to adapt appropriately to various levels of changes. (Contains 27 references.) (AEF)
