Abstract
Abstract In a system that accepts a given search entity from a user and utilizes a database to identify a possible matching entity from a large list of entries, a method is provided for evaluating the reliability of the matching entity. Preferably, the method is carried out with minimal human intervention. A user inputs a plurality of attributes to identify a given entity, the system identifies a possible matching entity, and assigns a numerical grade to reflect the match quality of each attribute. Thereafter, the method assigns a grade to each attribute score, assembles the grades into a key, uses the key to address a memory, and retrieves a confidence code or quality indicator from the memory. The confidence codes are based on empirical information and reflect the overall quality of the match for the particular entity.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
200 words
A method for utilizing and evaluating information, automatically and without human intervention, derived from a matching system, the matching system being of the type which searches an extensive database containing information on a plurality of entities, each entity being identified by a plurality of attributes, and the system being of the type which matches the attributes of an given entity with the attributes of entities stored within the database to indicate the identity of closely matching entities along with numerical scores for each attribute indicating the quality of the match for each of the attributes, the method comprising the steps of: assigning a grade to the score of a plurality n of the attributes, with the grade being selected from a small number of possible grades distinguishing between at least a clear match, a clear mismatch, and a possible match condition; assembling the grades for each of the n attributes to produce a key for a particular closely matching entity; and addressing a memory with the key to retrieve a match indicator that reflects the overall quality of the match for the particular entity, the memory containing matching indicators based on empirical information for the same or similar grade keys.
