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.
Claims13
A method for ranking a plurality of elements, wherein a numerical parameter characterizes each element, the method comprising:
- ranking a plurality of elements based at least in part on a Lorenizian fuzzy score based at least in part on a numerical parameter characterizing each element.
A method for ranking a plurality of elements, wherein a plurality of numerical parameters characterizes each element, the method comprising:
- ranking a plurality of elements based at least in part on an aggregate score;
- the aggregate score based at least in part on a plurality of Lorentzian fuzzy scores;
- each Lorentzian fuzzy score based at least in part on a numerical parameter characterizing each element.
