Abstract

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.
