In a document information processing apparatus handling a large amount of documents, when a document is registered, retrieval data for document retrieval is created for each registered document. Moreover, for each registered document, there is produced an access control table in which information indicating accessibility of groups including users as document retrievers for the document is registered. When a user desires to retrieve a document, accessibility of the user as the retriever is determined in accordance with the access control table for documents retrieved with retrieval data.

A document management system a high extendability, flexibility, and stability capable of solving a problem that, as an agent-oriented paradigm system extends, the number of agents increases and indefinite factors increase. In the system configuration with an object execution environment implemented with an object-oriented function and an agent execution environment implemented with an agent-oriented function, a unit for changing an agent into an object is provided for using the agent execution environment as the object execution environment. With this configuration, a system developer can use the merits of both the object- and agent-oriented paradigms by implementing a function necessary for stable operation by an object and a function with high change occurrence frequency by an agent.
