Abstract: A text cataloging method includes a step of cataloging already-analyzed-text data obtained from an analysis of a logical structure of a text to be cataloged in a text database, a step of creating a structure index by sequentially superposing logical structures of texts to be cataloged, wherein a single metaelement is used for representing a group of elements in the texts having the same position of appearance in one of the texts and the same element type, a single piece of meta-character-string data is used for representing a group of pieces of character-string data in the texts having the same position of appearance in one of the texts, and a context identifier is assigned to each metanode composing a tree-like structure of the structure index for uniquely identifying the metanode; a step of generating structured-full-text data composed of definitions of associative relations between all pieces of character-string data included in already-analyzed-text data of each text to be cataloged, and context identifie

Abstract: 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.

Abstract: A method of fast clipping, despite of large number of users, can be achieved through analyzing query expressions, storing the number of query terms included in the query expressions in a term number count table, generating a finite automaton for matching the terms occurring in text data with all terms included in the query expressions, generating a user identifier table for storing the identifiers of users in association with the terms included in the query expressions, matching the terms by scanning the text data by the finite automaton, calculating for each user the occurrence count of terms occurring in the text data as substrings coincident with the terms included in the query expressions made to the user identifier table, storing the calculated occurrence count in the term occurrence count region of the table, comparing the calculated term occurrence count of the table with the number of terms included the query expressions, and when a match is found from the comparison, delivering the text data to the u

Abstract: 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.

Abstract: A machine translation system capable of performing translation at a high processing speed with improved disambiguation rate in the parsing by applying grammar rules in dependence on the domains to which texts to be translated belong, objects of the texts and rules of sentences in the same text. The machine-translation system for translating a first language to a second language uses a grammer memory for storing grammar rules of the first or second language and a main memory for storing a variety of information, wherein the grammar rules stored in the grammar memory are prepared in groups at least on the basis of the domains to which texts to be translated belong and individual parts in the text.
