  • Patent number: 8694453
    Abstract: 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.

  • Publication number: 20090210411
    Abstract: 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.

  • Publication number: 20080270112
    Abstract: A translation evaluation device that evaluates the quality of a translation of an original text comprises a parallel translation storage unit (320) in which basic original texts (321) used as a basis for translation evaluation and correlated model translations (322) used as models for translation of the basic original texts are stored, an evaluation item input unit (310) to which a specific evaluation item (311) to be used for translation evaluation is input, a parallel translation extraction unit (225) that extracts from the parallel translation storage unit (320) a basic original text containing the evaluation item and a model translation corresponding to the basic original text, and a evaluation processor (240) that evaluates the quality of translation results (333) constituted with a translated text of the basic original text and input thereto, by comparing the translation results with the model translation (332) corresponding to the basic original text.

  • Patent number: 7031906
    Abstract: A conversation system according to the invention includes: a network; a server apparatus which transfers a conversation based on characters through the network; plural terminal apparatuses which perform the conversation based on the characters under the transfer by the server apparatus through the network; and a translating apparatus which is connected to the network, receives a conversation that is transmitted from one of the plural terminal apparatuses through the network and based on characters of one language, translates the received conversation based on the characters of one language into a conversation based on characters of another language, and transmits the translated conversation based on the characters of another language to the server apparatus. The server apparatus transfers the conversation that is received from the translating apparatus and based on the characters of another language to at least one terminal apparatus during a conversation among the plural terminal apparatuses.

  • Patent number: 7010479
    Abstract: The present invention provides an apparatus and method for natural language processing capable of providing an appropriate result of natural language processing. More specifically, the present invention provides a natural language processing apparatus for achieving a syntax analysis and/or a syntax generation by using natural language patterns with, at least, pattern name and pattern component. The natural language processing apparatus comprises dictionary reference means for picking up one or more natural language patterns applicable for the syntax analysis and/or the syntax generation among the natural language patterns prepared in a pattern dictionary in advance, pattern inspection means for inspecting whether the applicable natural language patterns meet a tree structure or not, and pattern application means for applying the natural language patterns to the tree structure if the natural language patterns meet the tree structure.

  • Patent number: 6098035
    Abstract: 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.
