An information distribution system is provided that can distribute various types of information without imposing extra workload on users. This information distribution system includes a server device that can access a profile DB and an information source DB. This server device includes an operation history recorder, a feature extractor, a profiler, an information collector, and an information distributor. Every time a user operates an information device, the server device obtains the operation history of the user. The operation history contains the user ID, the types of operations, and the text information of the handled document. The server device then linguistically analyzes the text information to extract the feature information. After performing weighting on the feature information, the server device registers the feature information in the profile DB. The server device then obtains information from the information source DB, and extracts the profile corresponding to the information from the profiles registered in the profile DB. The server device then distributes the information to the user having the extracted profile.

A language conversion system converts an original sentence in a source-language into a translated sentence in a target-language. The language conversion system includes a original analysis unit for analyzing the original sentence so as to obtain an intermediate structure of the original, an idea center extraction unit for extracting an idea center from the intermediate structure obtained by the original analysis unit, the idea center being a central expression of an idea to be described by a sentence, an identification unit for identifying a sentence pattern including the idea center extracted by the idea center extraction unit, an information extraction unit for extracting information required by the sentence pattern identified by the identification unit from the intermediate structure of the original sentence, a decision unit for deciding an intermediate structure of a translated sentence based on the sentence pattern and request information extracted by the information extraction unit, and a creation unit for creating a translated sentence in a surface level from the intermediate structure decided by the decision unit.
