Patent number: 8019761Abstract: A design support apparatus extracts feature data corresponding to design data to be searched upon receiving the design data to be searched. The apparatus checks the extracted feature data against the feature data associated with the feature associated information, ordering the design data associated with the feature associated information in descending order of similarity to the design data to be searched, retrieving one piece of the ordered design data. The apparatus generates a classification hierarchy consisting of pieces of classification data obtained by classifying a set of the retrieved design data based on a degree of feature similarity using the feature data associated with the feature associated information. The apparatus selects the design information closely associated with the classification data by fetching the design information corresponding to the design data contained in the classification data from the design associated information associating the design data and the design information.Type: GrantFiled: January 14, 2008Date of Patent: September 13, 2011Assignee: Fujitsu LimitedInventors: Yusuke Uehara, Takayuki Baba, Susumu Endo, Shuichi Shiitani, Daiki Masumoto, Shigemi Nagata
