The query might contain keywords , wildcards , wild parts of speech ( PoS ) , synonyms , and ad-ditional regular expression ( RE ) operators . In our approach , we incorporate inverted file in-dexing , PoS information from BNC , and se-mantic indexing based on Latent Dirichlet Al-location with Google Web 1T . The method in-volves parsing the query to transforming it in-to several keyword retrieval commands .
