  • Patent number: 8538745
    Abstract: A computer system of an embodiment of the disclosure can be used to automatically create or populate a terms dictionary using a set of computing units. A morphological analysis unit can acquire token sequence data by performing morphological analysis for the text data. A category distinguishing unit can distinguish tokens of the token sequence data by using a category dictionary to extract uncategorized words. An uncategorized-word comparing unit can compare each of the extracted uncategorized words with an uncategorized-word comparison rule to extract an uncategorized word matching the uncategorized-word comparison rule as a registration candidate word. A token-sequence comparing unit can compare a token sequence of the token sequence data with a token-sequence comparison rule to extract a token sequence matching the token-sequence comparison rule as registration candidate words. A permission unit can permit a user to select whether to register the registration candidate words in the category dictionary.

  • Patent number: 7949676
    Abstract: Using an ontology to perform an information search utilizing a meaning given to information on a network without being required to perform complicated operations for forming an inquiry sentence in conformity with the ontology. A pre-stage before a search engine provides an information search supporting system having a morpheme analysis section, a syntactic and semantic analysis section, and a conversion execution section which converts a natural language sentence on which syntactic analysis and semantic analysis have been performed into an inquiry sentence described in an ontology description language by referring to a case frame ontology dictionary in which are stored information indicating to which property in an ontology does the relationship among a predicate, a subject and an object in the natural language sentence correspond and the case frame of the natural language sentence in the property.

  • Patent number: 7013334
    Abstract: A network system comprising general management consoles 9, which are connected to the Internet 8; a supervisor management console 4, which can be accessed by a device management server 2; a database 5, which is connected to the device management server 2, wherein company data, correlated with each general management console 9, and device data, for each device 10 correlated with the company data, are stored; a console manager 3, for relaying the data processing; and means for referring to the company data and the device data to permit the correlated general management console to provide a correlated service or device or group. Since only a management console is installed in a company, the company is relieved of its responsibility for providing for the complicated operation of a management server. Furthermore, since the fee that an ISP may charge for providing a device management service for multiple companies can be split among the relevant companies, the expense incurred by each company can be reduced.
