Patent number: 7487081Abstract: A sentence generating method and apparatus for generating a joke sentence set having a dual meaning. A predetermined word in a selected first idiom is stored in a W list. A word of analogous sound having the pronunciation same as or analogous with the word in the W list and also being of the same word class as the word in the W list is stored in a RW list. It is then checked whether or not the subject word stored in the P list has a semantic relationship with the word of the analogous sound in the RW list. If the result of check is affirmative, a first joke sentence having the subject word in the P list and composed of the subject word of the P list and the first idiom is generated. A second idiom, corresponding to the first idiom, in which the word in the W list is replaced by the word of the analogous sound in the RW list, is generated, and a second joke sentence composed of the subject word of the P list and the second idiom is generated.Type: GrantFiled: September 13, 2002Date of Patent: February 3, 2009Assignees: Sony Corporation, Binsted-McKay Yugen-KaishaInventors: Hideki Shimomura, Masahiro Fujita, Keiichi Yamada, Ugo Di Profio, Justin McKay, Kimberly Binsted

Patent number: 7349850Abstract: The present invention relates to a program that allows a conversation to be performed with a user in a natural and human-like manner. Each of response candidate generating modules 54a through 54c generates response candidate data based on its own rule, in response to voice data input from the outside through an input module 51 and a response selecting module 52, and calculates a score of the response candidate data based on the response candidate data, the voice data and internal status data recorded in an internal status recording module 55, and then supplies the score to a response selecting module 52. In response to the supplied score, the response selecting module 52 selects, as response data responsive to the input voice data, one piece of response candidate data, and outputs the one piece of response candidate data through a response output module 53. The present invention is applicable to a voice interactive apparatus mounted on a robot, etc.Type: GrantFiled: July 26, 2002Date of Patent: March 25, 2008Assignee: Sony CorporationInventors: Hideki Shimomura, Masahiro Fujita, Ugo Di Profio

Patent number: 7103447Abstract: A robot (1) is provided which includes a situated behaviors layer (SBL) (58). This SBL (58) is formed in the form of a tree structure in which a plurality of schemata (behavior modules) is connected hierarchically in such a matter that the schemata are highly independent of each other for each of them to behave uniquely. A patent schema can define a pattern in which child schemata are connected, such as an OR type pattern in which the child schemata are caused to behave uniquely, AND type pattern in which the plurality of child schemata are caused to behave simultaneously or a SEQUENCE type pattern indicating a sequence in which the plurality of child schemata should behave, thereby permitting to select a behavior pattern of the robot (1). Also, a new child schema can additionally be included in the SBL (58) without having to rewrite the schemata connection in the tree structure, whereby a new behavior or function can be added to the robot (1).Type: GrantFiled: August 29, 2003Date of Patent: September 5, 2006Assignee: Sony CorporationInventors: Ugo Di Profio, Masahiro Fujita, Tsuyoshi Takagi, Yukiko Yoshiike, Hideki Shimomura

Publication number: 20060047362Abstract: No robot that can make a dialog customized for the user is known to date. According to the invention, various pieces of information appendant to an object are stored as values of the corresponding items of the object and a topic that is related to the topic used in the immediately preceding conversation is selected. Then, an acquisition conversation for acquiring the value of the item of the selected topic or a utilization conversation for utilizing the value of the item of the topic that is already stored is generated as the next conversation. The value acquired by the acquisition conversation is stored as the value of the corresponding item.Type: ApplicationFiled: December 2, 2003Publication date: March 2, 2006Inventors: Kazumi Aoyama, Yukiko Yoshiike, Shinya Ohtani, Rika Horinaka, Hideki Shimomura

Patent number: 6952665Abstract: A translating apparatus includes a speech recognition unit, a machine translation unit, a speech synthesizing unit, and a dialog management unit. The speech recognition unit recognizes input speech, and supplies the result of the speech recognition to the machine translation unit. The machine translation unit translates the result of the speech recognition. When a Japanese-speaking user and an English-speaking user speak to each other, the dialog management unit stores a history of dialogs, and determines based on the dialog history and prestored knowledge whether the result of the translation by the machine translation unit is unnatural compared with the flow of the dialog. When the result of the translation is unnatural, the dialog management unit outputs, to the machine translation unit, information representing the unnatural result. This controls the machine translation unit to perform translation again.Type: GrantFiled: September 29, 2000Date of Patent: October 4, 2005Assignee: Sony CorporationInventors: Hideki Shimomura, Kazuhiko Tajima, Seiichi Aoyagi, Hiroaki Ogawa

Patent number: 6850258Abstract: Icons indicating operating conditions of each of nodes (computers) constituting a system are individually displayed in the form of a loop. When the total number of the nodes exceeds a total number B of individual displays, nodes corresponding to B are displayed individually, and the rest are displayed in the form of a node collective icon. When a forward button is clicked, a display position of each of the node icons revolves clockwise one by one, a node that has been in the node collective icon is displayed individually at a position of a node icon, and an node icon at a position of a node icon is contained in the node collective icon. By clicking buttons a clockwise continuous revolving display, a counterclockwise revolving display and a counterclockwise continuous revolving display are performed. Node icons are highlighted so as to indicate abnormal conditions of the corresponding nodes.Type: GrantFiled: May 1, 2001Date of Patent: February 1, 2005Assignee: Fujitsu LimitedInventors: Fumio Saitoh, Yukari Itoh, Takahiro Uchiyama, Toru Kiura, Yoshihiro Mizuuchi, Hideki Shimomura
