CONTENT RETRIEVAL SYSTEM

摘要

A content retrieval system includes a grammatical analyzer cooperable with a set of grammar feature functions, at least one of the functions defining a pattern comprising: a required part-of-speech for at least one word of a sentence within a document, a set of character constraints for the word and a dependency relationship between the word and another word in the sentence within a document. The grammatical analyzer is arranged to apply at least one grammar feature function to a set of documents to identify documents including text conforming to the grammar feature function definition. The system further includes a user interface component arranged to enable a user to specify at least one of the set of grammar feature functions and to provide to the user a filtered set of the documents according to the documents including text conforming to the grammar feature function.
