METHOD AND SYSTEM FOR EXTENDING KEYWORD SEARCHING TO SYNTACTICALLY AND SEMANTICALLY ANNOTATED DATA

摘要

Methods and systems for extending keyword searching techniques tosyntactically and semantically annotated dataare provided. Example embodiments provide a Syntactic Query Engine ("SQE")that parses, indexes, and stores a data set as an enhanceddocument index with document terms as well as information pertaining to thegrammatical roles of the terms and ontologicaland other semantic information. In one embodiment, the enhanced document indexis a form of term-clause index, that indexes termsand syntactic and semantic annotations at the clause level. The enhanceddocument index permits the use of a traditional keywordsearch engine to process relationship queries as well as to process standarddocument level keyword searches. In one embodiment,the SQE comprises a Query Processor, a Data Set Preprocessor, a Keyword SearchEngine, a Data Set Indexer, an Enhanced NaturalLanguage Parser ("ENLP"), a data set repository, and, in some embodiments, auser interface or an application programminginterface.
