12. The computer-implemented method of claim 8 , further comprising: creating a query pseudo-document from the determined term vectors; and creating a leaned pseudo-document using the first pseudo-documents and the query pseudo-document; wherein identifying the first set of terms comprises using LSA of the leaned pseudo-document.
