First Claim
Patent Images
1. A computer-implemented method for ranking search results, comprising:
- determining a first property associated with each document in a collection of documents;
wherein the first property is a language type associated with the document;
determining a query language of a search query;
estimating a ranking value corresponding to properties for each document, wherein the ranking value corresponds to a measure of the relevance of each document based on the search query; and
ranking each document that is responsive to the search query to obtain the search results, wherein each document is ranked based on the estimated ranking value and a comparison of the query language with the first property value.

Abstract
Search results of a search query on a network are ranked according to an additional ranking function for the prior probability of relevance of a document based on document property. The ranking function can be adjusted based on a comparison of the language that a document is written in and the language that is associated with a search query. Both query-independent values and query-dependent values can be used to rank the document.
