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.

Abstract: To enable a user to perform, by using an ontology, an information search utilizing a meaning given to information on a network by Semantic Web without being required to perform complicated operations for forming an inquiry sentence in conformity with the ontology. In a stage before a search engine for performing an information search by using an ontology is provided 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.

Abstract: To dynamically classify and sort search results according to a natural language query and output the results conveniently, the invention includes an input unit for accepting entry of a natural language query, a natural language processing unit for performing natural language analysis of the query, a search unit for retrieving information using at least one keyword obtained through the natural language analysis, a search result processing unit for analyzing the keyword obtained through the natural language analysis of the query and its modifier, based on semantic content defined in an ontology, and processing the search results of the information retrieval by the search unit, such as sorting and classifying the results, and an output unit.

Abstract: The image data transferring apparatus of this invention determines that the change in the image is very small when a change in the image is not detected during a given time period, for example, and generates transmission data which causes image data displaying a full color image of, for example, 24 bits per pixel to be displayed in the receiving side in a relatively small number of frames in a unit time for transmission. Conversely, the image data transferring apparatus transmits reduced color data which is reduced from 24 bits per pixel to 4 bits per pixel in a relatively large number of frames in a unit time to the receiving side when it is determined that many changes are included in the image.
