20110270829 | SYSTEM, METHOD AND COMPUTER PROGRAM PRODUCT FOR INFORMATION SORTING AND RETRIEVAL USING A LANGUAGE-MODELING KERNAL FUNCTION - Various embodiments provide a system, method, and computer program product for sorting and/or selectively retrieving a plurality of documents in response to a user query. More particularly, embodiments are provided that convert each document into a corresponding document language model and convert the user query into a corresponding query language model. The language models are used to define a vector space having dimensions corresponding to terms in the documents and in the user query. The language models are mapped in the vector space. Each of the documents is then ranked, wherein the ranking is based at least in part on a position of the mapped language models in the vector space, so as to determine a relative relevance of each of the plurality of documents to the user query. | 11-03-2011 |
