Abstract: A center site is disposed to intervene in a business transaction achieved through a network. The center site includes an open business information database in which open business information received from member sites connected to the network is accumulated to be opened to the sites and a notarization database to keep therein contents of contracts of transactions between the sites. The center site receives a transaction request from a transaction partner site in accordance with the open business information and notifies the request to an information supply site associated therewith. The center site intervenes in a transaction resultantly accomplished between the information supply site and the transaction partner site and conducts a notarization process for the contents of contract for the transaction to accumulate the contract in a notarization database.

Abstract: In an electronic document circulating method of circulating an electronic document having a plurality of data blocks to a plurality of workers, a data block in a document is encrypted by using an encrypting key corresponding to a certain worker, and a document having the encrypted data block is transmitted and received over a network. A time necessary for encrypting and decrypting an electronic form may be reduced. The encrypted data block in the document is decrypted by using a decrypting key corresponding to a specific worker, and it is determined how to display the data block and execute a processing in response to whether or not the encrypted data block is decrypted correctly or the existence of the data block.

Abstract: A client computer obtains an execution file name of an application to be started from the constitution file information thereof and notifies the application distribution request information to a server computer and upon receipt of it, the server computer obtains the execution file name of the application, distributes a file constituting the application to the client computer when the client computer is registered in the license information, decides whether the distribution of the application succeeds or not from the notification result, and starts the application by the client computer. By doing this, generation and use of an application program are realized in the same development environment and even if an application in the client computer is updated at the start of the application, an application requested to the client computer from the server computer can be set up automatically and remotely.

Abstract: A hypothesis of co-occurrence relation information is generated from sentences and results of processing these sentences. Sentences for verification are generated based on the hypothesis. The adequacy of the sentences generated for verification is judged, and if the sentences are adequate, dictionary information including co-occurrence relation information is generated from the sentences for verification and the hypothesis which is the basis for the verification sentences.

Abstract: A natural language processing system for processing an original text by applying grammar rules, includes a grammar rule control table for holding information on applicability of the grammar rules to the original text, the information containing dictionary information associated with words appearing in the original text, and means for determining application or non-applicability application of each grammar rule based on the applicability information. The application conditions for applying each grammar rule are collectively evaluated or examined based on the information on the applicability of the grammar rules contained in the dictionary information and information on the text type, sentence type and domain of subject of the original text, and the result is stored in the grammar rule control table.
