摘要:
Based on reference information of a structured-document application program, structure information and contents of a structured document to be delivered are specified separately. Based on the specification, the structure information and the contents are obtained from a database which stores the structured document, to generate the structured document to be delivered. The generated structured document is delivered to the structured-document application program.

An information retrieval terminal provides keywords to an information retrieval device and instructs it to retrieve by using such keywords. The information retrieval terminal includes an information collector for collecting screen information, image information, and voice information around the information retrieval terminal and for obtaining text information from the collected information. A keyword-candidate extracting unit extracts a word related to a retrieval word input by a retriever from the text information obtained by the information collector, and sets the extracted word to be a keyword candidate. A retrieval instructing unit gives an instruction to retrieve by using the retrieval word and the keyword candidate set by the keyword-candidate extracting unit as keywords.
摘要:
A user inputs a retrieval query represented by a set of propositions using a modal operator through an interface. The retrieval query is passed to a document set gathering unit through a retrieval input unit. The document set gathering unit refers to an index, gathers a set of documents having a true proposition, and writes it to a work area. A similarity computation unit computes the similarity of the gathered set of documents and writes it to the work area. The retrieval result output unit refers to the work area, ranks the gathered sets of documents in consideration of a true/false value and a similarity, and the ranking result to the interface as a retrieval result. A common keyword extraction unit extracts a keyword for output from the ranked sets of documents, and outputs the keyword after adding a corresponding modal operator to the keyword to the interface.

An information searching apparatus retrieves a sub graph matching an inquiry graph from a graph to be searched. The apparatus includes an extracting unit that extracts, from among clusters of nodes in the graph to be searched, plural cluster pairs that each include a first cluster and a second cluster including a node linked by a link to a node in the first cluster and a calculating unit that calculates a bonding strength for each of the cluster pairs. The apparatus further includes a determining unit that determines, among the cluster pairs and based on the bonding strength of each of the cluster pairs, a cluster pair to be merged; a merging unit that merges the cluster pair; and a searching unit that searches the merged clusters for a sub graph matching the inquiry graph. An output unit outputs a search result of the searching unit.

摘要:
A query in which a sibling relationship among document parts, which are elements of a structured document, can be designated as a search condition is input, and a query tree which represents the query in a tree structure is created. A query converting unit refers to a hierarchical index in which a hierarchical relationship among document parts of each structured document to be searched is expressed in a tree structure, and converts the query tree to a Boolean expression. A text-index referring unit refers to a text index in which is registered information representing a relationship between each set including a character string in text data and a part-ID of a meta part and a document-ID of a document, thereby searching a document corresponding to the Boolean expression converted from the query tree.
摘要:
A collating apparatus generates a sparse state transition table by reducing the amount of data indicating a specific transition operation and a shift operation in a state transition table in which a collating operation corresponding to each symbol contained in one or more retrieval keys is defined. Then, the collating apparatus stores the table after compressing it into an array format, and retrieves the keys in the file to be retrieved while referring to the compressed state transition table. This collating apparatus is applied to a word processor, database system, full-text search system, etc.

摘要:
A compression unit compresses original data in block units and encodes compressed data, and it generates continuation flag information expressive of the block length of the compressed data at the top part of the compressed data stored in a storage unit. An expansion unit determines the block length of the remaining data of the compressed data on the basis of the continuation flag information, fetches the remaining data from the storage unit and restores the original data.
