Search By Document Type And Relevance
A method of finding documents. A method of finding documents comprising, ranking documents according to relevance to form a ranked relevance list, ranking documents according to type to form a ranked type list, and combining the ranked relevance list and the ranked type list to form a list of documents ranked by relevance and type.
1 . A method of searching by document type comprising:
ranking documents according to relevance to form a ranked relevance list:
ranking documents according to type to form a ranked type list; and
combining the ranked relevance list and the ranked type list to form a list of documents ranked by relevance and type.
2 . The method of searching by document type of claim 1 further comprising learning a relevance model from a set of relevance model training data.
3 . The method of searching by document type of claim 2 in which the relevance model set of training data includes a query, a document, and a label.
4 . The method of searching by document type of claim 1 further comprising learning a type model from a set of type training data.
5 . The method of searching by document type of claim 4 in which the type model set of training data includes a document and a label.
6 . The method of searching by document type of claim 1 in which interpolation is performed by linear combination.
7 . The method of searching by document type of claim 1 in which interpolation is performed by thresholding.
8 . The method of searching by document type of claim 1 in which ranking documents according to relevance to form a ranked relevance list is performed by a document relevance search.
