  • Patent number: 5414797
    Abstract: A system provides a tool for computing the most typical fuzzy expected value of a membership function in a fuzzy set. The clustering fuzzy expected value system is used in a question answering system. CFEV is computed by the tool is based on grouping of individual responses, that meet certain criteria, to clusters. Each cluster is considered a "super response" and contributes to the result proportionally to its relative size and the difference in opinion from the mean of the entire sample. In so doing, CFEV represents the opinion of the majority of the population, but it also respects the opinion of the minority. A comparison is made with existed tools such as the FEV and the WFEV and the advantages of CFEV are demonstrated by examples for cases where other methods fail to perform.

  • Patent number: 5384894
    Abstract: A system provides question answering based on fuzzy logic. The proposed system provides the capability to assess if a database contains information pertinent to a subject of interest by evaluating each comment in the database via a fuzzy evaluator which attributes a fuzzy membership value indicating its relationship to such subject. An assessment is provided for the database as a whole regarding its pertinence to the subject of interest, and consequently comments that are considered as irrelevant to the subject may be discarded. The system has been developed for the examination of databases and evaluated by testing against those which were created for assessing whether computer system development databases contain information pertinent to the functional changes that would occur in the development cycle. The system can be applied with minimal changes to a variety of circumstances provided that the fundamental assumptions for the development of the membership functions are respected for the application.

  • Patent number: 5233611
    Abstract: A computer system utilizes a single computer to test the operability of an application which also runs on the same computer. The computer system comprises a processor and a multi-tasking operating system, which is able to execute programs asynchronously and independently of each other in logical environments called sessions. A test case program executes during a first session, and tests an applications program which executes in a second session on the same computer system independently of the test case. The test case program includes commands to input keystrokes to the application under test for processing by the application under test. A test program reads the keystroke and the command from the test case and packetizes the keystroke and command. The test program also runs during the first session. A communication program runs on the processor during a second session and communicates the packetized keystroke and command to the operating system for input to the application under test.
