NEW DIFFERENTIAL LSI SPACE-BASED PROBABILISTIC DOCUMENT CLASSIFIER |
摘要 |
A method for automatic document classification based on a combined use of the projection and the distance of the differential document vectors to the differential latent semantics index (DLSI) spaces. The method includes the setting up of a DLSI space-based classifier and the use of such classifier to evaluate the possibility of a document belonging to a given cluster using a posteriori probability function.
