Patent number: 8966502Abstract: Collecting log data efficiently by controlling the capturing event for an operation log on the basis of application layer information. A web server generates a response including an operation log capturing script and the information from an operation log capturing control definition table and a property capturing definition table, and sends the response to a client. In the client, the received information is forwarded from a web browser module to a script engine module. An operation log capturing module sets the information acquisition event handler on the basis of the forwarded information, captures a sequential operation log on the basis of the operations performed by a user in the web browser, and sends the captured sequential operation log to a log server. A log server module collects sequential operation log in an operation log table, and a log analysis module analyzes the collected logs.Type: GrantFiled: September 1, 2010Date of Patent: February 24, 2015Assignee: Hitachi, Ltd.Inventors: Katsuro Kikuchi, Masashi Egi, Takao Sakurai, Daisuke Tashiro

Publication number: 20110029559Abstract: 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.Type: ApplicationFiled: February 24, 2010Publication date: February 3, 2011Inventors: Katsuro KIKUCHI, Keisuke Matsubara, Katsushi Yako, Ken Naono
