Abstract
A relevant-information retrieval system manages a model which describes a relevancy among a plurality of databases in accordance with associative values or a tree structure. Besides, when the retrieval system has received a search request for a certain database from a searcher, it specifies one of the databases administering information relevant to the certain database, in accordance with the model, and it presents information of the specified database to the searcher.
Claims20
A relevant-information retrieval system which governs a plurality of independent databases, and which presents information on a database administering information relevant to information of a search request, to a source having issued the search request for the plurality of databases, comprising:
- a management unit managing an association model which describes a relevancy among said plurality of databases in accordance with an associative value defined between two of said databases and representing a degree of association between the two of the databases;
- a specification unit operating in a search process for a certain one of said plurality of databases, and specifying one of said databases administering information relevant to the certain database, in accordance with the association model managed by said management unit;
- and
- a presentation unit presenting the search request issuing source with information of the database specified by said specification unit.
A relevant-information retrieval system comprising:
- a management unit managing an association model which describes a relevancy among a plurality of databases in accordance with an associative value defined among the plurality of databases and representing a degree of association among the databases;
- a specification unit operating upon receiving a search request for a certain database, and specifying a database administering information relevant to the certain database, in accordance with the association model;
- and
- a presentation unit presenting information of the specified database.
A relevant-information retrieval system which governs a plurality of independent databases, and which presents information on a database administering information relevant to information of a search request, to a source having issued the search request for the plurality of databases, comprising:
- a management unit managing a database model which describes a relevancy among said plurality of databases in accordance with a tree structure having nodes corresponding to the databases;
- a specification unit operating in a search process for a certain one of said plurality of databases, and specifying one of said databases administering information relevant to the certain database, in accordance with the database model managed by said management unit;
- and
- a presentation unit presenting the search request issuing source with information of the database specified by said specification unit.
A relevant-information retrieval system comprising:
- a management unit managing a database model which describes a relevancy among a plurality of databases in accordance with a tree structure having nodes corresponding to the databases;
- a specification unit operating upon receiving a search request for a certain database, and specifying a database administering information relevant to the certain database, in accordance with the database model;
- and
- a presentation unit presenting information of the specified database.
A program recording medium storing therein a program for a computer which governs a plurality of independent databases, and which presents information on a database administering information relevant to information of a search request, to a source having issued the search request for the plurality of databases, the stored program causing the computer to execute:
- a specification process occurring in a search process for a certain one of said plurality of databases, for specifying one of said databases administering information relevant to the certain database, in accordance with an association model which describes a relevancy among said plurality of databases on the basis of an associative value defined between two of said databases and representing a degree of association between the two of the databases;
- and
- a presentation process for presenting the search request issuing source with information of the database specified by said specification process.
A program recording medium storing therein a program for a computer which governs a plurality of independent databases, and which presents information on a database administering information relevant to information of a search request, to a source having issued the search request for the plurality of databases, the stored program causing the computer to execute:
- a specification process occurring in a search process for a certain one of said plurality of databases, for specifying one of said databases administering information relevant to the certain database, in accordance with a database model which describes a relevancy among said plurality of databases on the basis of a tree structure having nodes corresponding to the databases;
- and
- a presentation process for presenting the search request issuing source with information of the database specified by said specification process.
A relevant-information retrieval method comprising:
- generating an association model which describes a relevancy among a plurality of databases in accordance with an associative value defined among the plurality of databases and representing a degree of association among the databases;
- receiving a search request for a certain database;
- specifying a database administering information relevant to the certain database, in accordance with the association model;
- and
- presenting information of the specified database.
A relevant-information retrieval method comprising:
- generating a database model which describes a relevancy among a plurality of databases in accordance with a tree structure having nodes corresponding to the databases;
- receiving a search request for a certain database;
- specifying a database administering information relevant to the certain database, in accordance with the database model;
- and
- presenting information of the specified database.
A method comprising:
- generating an association structure including nodes representing databases, selected nodes being linked with associative values representing a degree of association between the linked databases represented by the linked nodes;
- and
- upon receiving a search request for a particular database, identifying an associated database associated with the particular database by searching the association structure.
A computer readable storage medium, storing a program instructing a computer to perform:
- generating an association structure including nodes representing databases, selected nodes being linked with associative values representing a degree of association between the linked databases represented by the linked nodes;
- and
- upon receiving a search request for a particular database, identifying an associated database associated with the particular database by searching the association structure.
An apparatus comprising:
- a management unit managing an association structure including nodes representing databases, selected nodes being linked with associative values representing a degree of association between the linked databases represented by the linked nodes;
- and
- a specifying unit identifying an associated database associated with a requested database by searching the association structure stored in the management unit.
