Patent number: 8694453Abstract: A dialogue control system that uses an ontology that systematically expresses domain knowledge representing concepts and relationships between concepts to determine questions for a user and implements the questions, and implements a dialogue in accordance with received user answers. One or more dimension-classified ontologies and a basic ontology are stored, a concept from a user response is specified as a condition, and one or a plural number of the dimension-classified ontologies that meet the specified condition are fetched. The content of the fetched dimension-classified ontology/ies is overwritten on the basic ontology, in order according to dimension priorities from the dimension-classified ontology with the lowest dimension priority, and a multidimensional ontology is generated. The dialogue control system uses this multidimensional ontology to control the dialogue.Type: GrantFiled: December 15, 2009Date of Patent: April 8, 2014Assignee: Oki Electric Industry Co., Ltd.Inventors: Mihoko Kitamura, Toshiki Murata, Tatsuya Sukehiro, Sayori Shimohata, Ikuo Orihara, Atsushi Ikeno, Shigehiro Kato, Miho Tanaka

Publication number: 20090210411Abstract: A user speech analyzing component poses, to a user, question sentences for respective ones of a plurality of attributes, and analyzes an attribute value for each of the attributes from an answer sentence from the user to the sentence question. A user data holding component, as a result of analysis, holds user data that allows the plurality of attributes, and respective user attribute values for the attributes to correspond to one another. A matching component, when an acquisition ratio of the attribute values from the user with respect to all of the attributes is a predetermined value or greater, selects at least one target data candidate that matches each of the attributes and each of the attribute values of the user data, from a plurality of target data. A dialogue control component outputs each of the target data candidates selected, to the user's side.Type: ApplicationFiled: November 19, 2008Publication date: August 20, 2009Applicant: OKI ELECTRIC INDUSTRY CO., LTD.Inventors: Toshiki Murata, Mihoko Kitamura, Tatsuya Sukehiro, Takeshi Yamamoto, Tadashi Fukushima, Sayori Shimohata, Atsushi Ikeno

Patent number: 6098035Abstract: There is provided a morphological analysis method and device whereby, even if unknown words are present, processing can be effected with high accuracy and at high speed and economy of resources can be achieved. Expanded characters e.sub.i are generated by adding to each character c.sub.i of input text, in addition to word division information d.sub.i, expansion information including required arbitrarily selectable information such as tag information, and all possible expanded character sequences are generated. Beforehand, by training, the partial chain probabilities (appearance probabilities) of N-gram (where, normally N=1 or 2 or 3) character sequences are stored in an expanded character table.Type: GrantFiled: March 19, 1998Date of Patent: August 1, 2000Assignee: Oki Electric Industry Co., Ltd.Inventors: Hideki Yamamoto, Mihoko Kitamura, Sayori Shimohata, Mikio Yamamoto
