ABSTRACT:
A system extracts a pair that includes a keyword candidate and information associated with a document from multiple documents, and calculates a frequency that the keyword candidate appears in search queries and a frequency that the pair appears in the multiple documents. The system also determines whether the keyword candidate is a keyword for a category based on the calculated frequencies, and associates the keyword with the document if the keyword candidate is the keyword for the category.
