This paper describes an evaluation of an existing technique that locates sentences containing descriptions of a query word or phrase. The experiments expand on previous tests by exploring the effectiveness of the system when searching from a much larger document collection. The results showed the system working significantly better than when searching over smaller collections. The improvement was such, that a more stringent definition of what constituted a correct description was devised to better measure effectiveness. The results also pointed to potentially new forms of evidence that might be used in improving the location process. Keywords Information retrieval, descriptive phrases, WWW.
