  • Patent number: 8296045
    Abstract: The present invention provides a traffic information processing apparatus and method, the apparatus comprises a format unifying device which unifies input traffic information with different formats to traffic information with unified format; and a traffic information integrating device which corrects and/or complements the traffic information with unified format based on a knowledge base to obtain traffic information which is consistent with each other, so as to integrate the traffic information, wherein the knowledge base is external to the apparatus or internal to the apparatus. The traffic information processing apparatus and method according to the present invention can process traffic information with spatial inconsistence, temporal inconsistence and semantic inconsistence so as to integrate effectively the traffic information from a variety of heterogeneous information sources and ensure the accuracy, completeness and reliability of traffic data.

  • Patent number: 8180628
    Abstract: The present invention provides an apparatus for expanding a query requirement, comprising: a query requirement understanding device which generates an explicit query requirement according to a user query request; and a query requirement expanding device which generates an implicit query requirement associated with the explicit query requirement. The query requirement understanding device generates an explicit query requirement including a query concept and a question type by searching a knowledge base and a language base, and the query requirement expanding device generates an implicit query requirement including a query concept and a question type by searching the knowledge base, the language base and a relevancy database. The present invention further provides a method for expanding a query requirement. The apparatus and method for expanding a query requirement according to the present invention can facilitate a user's query and provide the user with an accurate, comprehensive query answer.

  • Patent number: 7937402
    Abstract: A natural language based location query system and a method thereof. The system comprises a receiving device which receives a request for natural language query from a user terminal; an access device which accesses a location ontology base and a location query language base that are external to the system or internal in the system, wherein the location ontology base comprising knowledge descriptions about the field of a location service, and the location query language base comprising a language model for the location service query; a natural language query processing device which performs at least one of a fuzzy processing and an indirection processing on the received request for natural language query by searching the location ontology base and the location query language base with the access device, retrieves location information corresponding to the request from a location database; and a sending device which sends the location information to the user terminal.

  • Patent number: 7908075
    Abstract: The invention provides a map knowledge base generating device and a method thereof, and a traffic information query system and a method thereof. The traffic information query system, comprises: a map knowledge base generating section for generating knowledge related to attributes of roads and traffic points, attribute values corresponding to the attributes, and spatial information of the attribute values based on an electronic map so as to form a map knowledge base; and a traffic query processing section for receiving and analyzing a query form a user terminal, decomposing the query if it is determined that the query can be decomposed according to the map knowledge base, and searching a traffic information database according to the decomposed the query request.
