Apparatus and methods for an information retrieval system that employs natural language processing of search results to improve overall precision

摘要: Apparatus and accompanying methods for an information retrieval system that utilizes natural language processing to process results retrieved by, example, engine such as a conventional statistical-based search engine, in order improve overall precision. Specifically, ultimately yields set of documents. Each document is then subjected produce logical forms. form encodes, word-relation-word manner, semantic relationships, particularly argument adjunct structure, between words phrase. A user-supplied query analyzed the same manner yield corresponding forms therefor. Documents are ranked predefined function from documents query. compared against each ascertain match any both sets. has at least one matching heuristically scored, with different relation being assigned weight. The score is, e.g., weights its uniquely Finally, retained descending presented user order.
