  • Patent number: 7707139
    Abstract: A process for document registration is executed with a structured document of a file as an input. An analyzed structured document and information for document search are generated and stored in databases, respectively. A query input is analyzed, a document search index is read and a search process is executed, producing matching document identifier information and matching strings position information. Then, a corresponding analyzed structured document is read from the database based on the document identifier information, the matching information is embedded in the structured document based on the matching strings position information, and a structured document with added highlight information is generated and displayed. A document is searched from which the element information constituting a stumbling block to the search is removed, and the result of the search is displayed with highlight information added to the original structured document.

  • Patent number: 7107527
    Abstract: In a structured document managing method and system for managing a structured document formed by a plurality of elements, any file forming a registered document is selected as an object of updating from relationship data indicating an entity structure and a logical structure of the registered document and the data content of the selected update object file is updated. There is generated partial relationship data which indicates an entity structure and a logical structure of the update object file after updating. Relationship data of the registered document is updated by use of the generated partial relationship data. Thereby, a logical structure and an entity structure possessed by a document are managed in association with each other in a mutually convertible form.

  • Patent number: 6869378
    Abstract: A series of motors with speed reducers which can meet user demands for reduction ratios or requests for the types of speed reducers with flexibility and reliability and can lower noise and vibration level. When a plurality of types of speed reducers are combined with motors to make arbitrary motors with speed reducers selectable, a plurality of simple planetary roller units 120 each including a sun roller 121, planetary rollers 122, and a ring roller 123 are provided. The plurality of simple planetary roller units 120 are selected and coupled to covers 110 around the output shafts of the motors to make a plurality of medium-speed motor groups SMC configurable. The plurality of types of speed reducers are selectable and connectable to medium-speed motors of the same size through a carrier 100 for synchronizing with the revolution component of the planetary rollers 122.

  • Patent number: 6745202
    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

  • Patent number: 6510425
    Abstract: A document search method and apparatus and a portable medium used therefor are described, in which when registering a document in a data base, the logic structures of each document to be registered are superposed one on another to generate a structure index in which the structure elements having the same position of occurrence in the document are represented by a single meta-node. At the time of document search, a mass of the meta-nodes meeting a specified structural condition is determined with reference to the structure index. A string index is searched with the meta-node identifiers as a key thereby to determine a mass of documents meeting the specified condition. As a result, a highly accurate structure-specified search is made possible on a document data base including a mass of structured documents.

  • Patent number: 6490583
    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 and an apparatus for searching and displaying a structured document are disclosed. The process for document registration is executed with a structured document of a file as an input. An analyzed structured document and information for document search are generated, and are stored in data bases, respectively. A query input from an input/output unit is analyzed, a document search index is read and a search process is executed. Matching document identifier information and matching strings position information are output as the result of search. In the display process, a corresponding analyzed structured document is read from the data base based on the document identifier information matched in a document read process. In processing a document display, the matching information are embedded in the structured document based on the matching strings position information, and a structured document for display with highlight information added thereto is generated and displayed.
