Abstract
A computer-based searching method is described that includes receiving, at a computer, a search concept that includes a plurality of principal words, determining a set of semantically similar words for at least one of the principal words, calculating a degree of membership for each word in each set that reflects a semantic similarity in meaning to the principal word of the set, performing the search, computing a score based at least on the degrees of membership for the words in the word set, and sorting the results using the computed scores.
Claims22
A computer-based searching method comprising:
- receiving, at a computer, a search concept that includes a plurality of principal words;
- determining a set of semantically similar words for at least one of the principal words;
- calculating a degree of membership for each word in each set that reflects a semantic similarity in meaning to the principal word of the set;
- performing the search;
- computing a score based at least on the degrees of membership for the words in the word set;
- and
- sorting the results using the computed scores.

A computer programmed to:
- receive, via a computer interface, a search concept query that includes a plurality of principal words;
- amplify at least one of the principal words to a set of semantically similar words;
- calculate a degree of membership for each word in each set that reflects a similarity in meaning to the principal word of the set;
- perform the search utilizing each of the sets;
- compute a score for each document resulting from the search based at least on the degrees of membership for the words in the principal-word sets;
- and
- use the computed scores to rank the documents.
