  • Publication number: 20110029559
    Abstract: Even when the operation of web page referencing or search is discontinuous and implicit, relativity between web pages is extracted. A web relativity extraction unit is executed as a program by the processing unit of a recommendation server. The web relativity extraction unit extracts relativity between web pages about a search term related to the web pages. Further, it considers a user's information search model based on the process of accessing between web pages and quantitatively evaluates a relativity degree indicating the intensity of relativity and thereby extracts relativity between the web pages.

  • Patent number: 7739083
    Abstract: When a parameter for a numerical computation library is required, an optimum parameter reflecting a user policy is provided. A program calculates, based on a preset objective function, an optimum tuning parameter for executing a numerical computation library. The program reads the numerical computation library; reads the objective function; sets a user policy regarding speed performance and computational accuracy of the numerical computation library as plural policy parameters; reads, from preset execution histories of numerical computation libraries, execution histories of the numerical computation library; calculates, in a domain where the policy parameters are met and based on the execution histories having been read in, a tuning parameter for the numerical computation library by using the objective function; and outputs a calculation result of the objective function.
