  • Database management system
    Patent number: 7424492
    Abstract: The present invention is related to a database management system that is capable of autonomous dynamic ontology management through soft classing. The present invention is further related to a method of database management by dividing attribute data, e.g., price=10 dollars, into class elements containing data, e.g., attribute name=price, type=numeric, default units=dollars, and entry elements containing data, e.g., attribute value=10, to permit dynamic ontology management and evolution in the database through soft classing.
    Type: Grant
    Filed: September 30, 2005
    Date of Patent: September 9, 2008
    Assignee: Science Applications International Corporation
    Inventors: Yun-Tung Lau, Richard Chipman, Peter Poon, Kiran Kuchipudi
  • Data ranking with a lorentzian fuzzy score
    Publication number: 20070271261
    Abstract: The present invention relates to a method for searching a document database such as the Internet and ranking the results obtained from such a search. The invention also relates to ranking of a set of numerical data according to a set of user specified preferences, including target range, fuzziness and bias. A fuzzy score is calculated for each database record satisfying a query and the results ranked according to fuzzy score. The fuzzy score is calculated using a Lorentzian fuzzy score formula.
