Publication number: 20130117303Abstract: A data search device acquires memo data to be used in a search, extracts keywords from the memo data, and then allocates ranks to the keywords. The data search device performs a search for the keywords in multiple databases to identify related data. The databases are ranked similarly to the keywords. When multiple items of related data are identified, the data search device calculates overall ranks based on the ranks of the keywords and the ranks of the databases used in the search of the items of related data, and outputs items of related data having higher ranks.Type: ApplicationFiled: May 12, 2011Publication date: May 9, 2013Applicant: NTT DOCOMO, INC.Inventors: Akane Morimatsu, Naoki Hashida, Kantaro Suzuki, Misa Yamamoto
