SYSTEM AND METHOD FOR USER INPUT SEARCH CONDITIONS TO RETRIEVE INTEGRATED SUBSTANCES PHYSICAL PROPERTY DATA, AND RETRIEVE SYSTEMATICALLY CLOSE SUBSTANCES TO SPECIFIED RECORDS BASED UPON DETERMINED SYSTEMATIC DEGREES OF SIMILARITY BETWEEN THE SUBSTANCES, FROM PLURALITY OF TARGET DATABASES

摘要

A system for retrieving information from a plurality of databases, even when the content of the databases is different. A target database-extracting device extracts databases containing data that has been sought to retrieve. An integrated information retrieval device integrates data from the extracted databases and retrieves records from the databases matching retrieval conditions. A systematic retrieval device retrieves other record from the extracted databases that are systematically close to the records designated to be retrieved. The systematic closeness between records is calculated as a function of the degree of similarity between information in the records. Records are calculated A retrieval result display device displays the results of the retrieval by the integrated retrieval device and by the systematic retrieval device.
