Publication number: 20070073646Abstract: In a user profiler used for program recommendation, a user profile which differs particularly according to the season is extracted, saved and appropriately re-used. For this purpose, there are provided a user profiler which extracts user profiles based on program information and a user's view history, and a profile memory which incrementally saves the profiles in a time series based on time information acquired from a timer in the user profiles. The profile memory generates and saves total profile information which is obtained by summing the profiles to be saved for predetermined periods. A total profile memory is also provided which saves the total profile information for these periods when a fixed time has elapsed, and the total profile information which was saved by the total profile memory is re-saved by the profile memory at a certain specified time.Type: ApplicationFiled: July 20, 2006Publication date: March 29, 2007Inventors: Konagi Uchibe, Hiroyuki Kumai, Yasutsugu Morimoto

Publication number: 20040260979Abstract: This invention relates to an information mining system capable of mining data stored in a database in a high efficiency. The information mining system includes an operation history data holding unit for recording both an operation history of the analyzing tool carried out in the past in the analyzing operation, and an operation history of the analyzing tool; and a history comparing unit for judging whether or not the operation history is resembled to the operation history of the analyzing tool, and operated in such a manner that when the history comparing unit judges that the operation history of the analyzing tool is resembled to a portion of the operation history of the analyzing tool, the history comparing unit notifies the partial resemblance of the operation history with respect to the analyzing tool.Type: ApplicationFiled: March 2, 2004Publication date: December 23, 2004Inventor: Hiroyuki Kumai

Publication number: 20040158558Abstract: Disclosed is a text mining method with steps for separating high frequency information and low frequency information and applying an ideal analysis method to each kind of information. Negative expressions and modality expressions are extracted from the low frequency information to assist in extracting valuable knowledge for risk management. Text classification technology by the conventional key word method is suitable for extracting and classifying high frequency knowledge but extracting valuable information for risk management or from the actual customer voice in the call center text database requires extracting the essential valuable knowledge from vast quantities of ordinary information. This method has a function to hold in a folder the document found by a keyword search, and a function to store the remaining text into a low frequency information folder, after having stored the high frequency information found by keyword search.Type: ApplicationFiled: July 22, 2003Publication date: August 12, 2004Inventors: Atsuko Koizumi, Yasutsugu Morimoto, Hiroyuki Kumai, Naoto Akira

Patent number: 6094186Abstract: In a document processing apparatus wherein when a format of a document or the like is set, a plurality of format patterns are simultaneously displayed, a selection is made of a desirable format pattern among said format patterns so as to perform a format setting operation, displays of the format patterns are subdivided into a plurality of screens based on a purpose or usage of a document to be formed. After selecting or designating the purpose or usage of the document, the above-described format pattern is displayed. The document format setting operation which was cumbersome in prior art can be readily performed by selecting a desirable format sample from the format samples which have been categorized based upon the usage thereof, and also by adding an item capable of freely setting a format into the format samples.Type: GrantFiled: May 15, 1995Date of Patent: July 25, 2000Assignee: Hitachi, Ltd.Inventors: Masayoshi Kuroda, Yasumasa Matsuda, Hiroyuki Kumai, Yasuhiko Kasai, Kiyoshi Masuda, Akihiro Kaneko, Junichiro Takeyama

Patent number: 5781731Abstract: When conference conditions are set by a conference sponsor, a conference sponsor agent inquires of schedule management agents of requested attendants about available time within a range of set dates, determines an optimum conference schedule on the basis of the available time of the individual requested attendants, sends to the conference sponsor the conference schedule for confirmation thereof, and sends a conference notification to the requested attendants. In order to permit an input value set by a user to have a range in accordance with the kind of parameter requiring the input value and conditions at that time, an input value acquiring element acquires an input value of a parameter necessary for a processing realized by an application element, the input value being set by the user by an input element.Type: GrantFiled: September 20, 1996Date of Patent: July 14, 1998Assignee: Hitachi, Ltd.Inventors: Hiroyuki Koreeda, Yasuhiko Kasai, Tsukasa Yamauchi, Hajime Asuma, Shigeto Oeda, Jun Ito, Hiromi Tomita, Tsukasa Hasegawa, Rituko Kanazawa, Yoshiisa Inoue, Hiroyuki Kumai, Shigeki Hataya, Akira Nakajima, Yasumasa Matsuda

Patent number: 5634134Abstract: A method and apparatus for determining at least one of a character and a destination therefor in accordance with a received signal representing at least one of a plurality of characters and at least one character corresponding to at least one of a plurality of languages. Likelihood values for at least one of plurality of characters and each of the languages are evaluated, and at least one of the plurality of characters and one of the character languages are selected in accordance with the evaluated likelihood values thereof.Type: GrantFiled: June 19, 1992Date of Patent: May 27, 1997Assignee: Hitachi, Ltd.Inventors: Hiroyuki Kumai, Jun Ito, Akira Nakajima, Yasumasa Matsuda, Shigeki Taniguchi, Hirobumi Kashiwa, Toyokazu Suzuki, Masaki Kawase

Patent number: 5612720Abstract: A system for processing information with an electronic pen includes a coordinates indicating device and a coordinates sensing device. Both of the devices serves to output the information stored in itself to each other and store the information outputted from the other. The power supply for driving the information processing system itself is fed by a battery built in the coordinates indicating device.Type: GrantFiled: June 7, 1995Date of Patent: March 18, 1997Assignee: Hitachi Ltd.Inventors: Jun Ito, Hiroyuki Kumai, Yasumasa Matsuda, Akira Nakajima, Yoshiisa Inoue, Hiroyuki Koreeda, Shigeto Oheda

Patent number: 5535119Abstract: An information processing equipment providing easy operations of changing-over character species, and, in which characters can be entered without being conscious of the designation of a character mode. Signals entered from an input device are handled in conformity with all of a romaji (Roman character) input system, a kana (Japanese syllabary) input system and an alphanumeric input system. Results obtained with the respective input systems are all displayed in the predetermined part of a display screen. In the equipment, the character mode intended by a user is estimated as to the entered character string, and is automatically selected. In another aspect of performance, a controller determines whether or not a character mode likelihood decision unit and a character code translation unit are started, in accordance with the results of the comparisons between the key code string and the registered contents of a learning information buffer.Type: GrantFiled: June 11, 1993Date of Patent: July 9, 1996Assignee: Hitachi, Ltd.Inventors: Jun Ito, Yasumasa Matsuda, Hiroyuki Kumai, Akira Nakajima, Shigeki Taniguchi, Hirobumi Kashiwa, Toyokazu Suzuki, Masaki Kawase, Hiromi Tomita
