Abstract
A dialogical information search system is realized by comprehensively utilizing different kinds of ontologies: a library classification system and a Wikipedia category. A new information search infrastructure is thus realized by comprehensively utilizing the different ontologies of library classification system and Wikipedia category. By virtue of this, a new information search paradigm can be promoted to the world: an in-depth search is realized by utilizing a library with the Web as a clue. This, as a result, contributes to improving literacy of the whole society, and conduces to rediscovering the significance of existence of libraries and further to realizing electronic libraries.
Claims17
An information search system for carrying out an information search based on a search request from a user, the system comprising:
- a first search means for searching a folksonomic ontology on the basis of the search request;
- an extraction means for extracting a concept from a library ontology in relation to an acquired concept through searching the folksonomic ontology;
- and
- a second search means for searching the library ontology by utilizing the concept extracted by the extraction means.
An information search method for carrying out an information search based on a search request from a user, the method comprising:
- a first search step of searching a folksonomic ontology on the basis of the search request;
- an extraction step of extracting a concept from a library ontology in relation to an acquired concept through searching the folksonomic ontology;
- and
- a second search step of searching the library ontology by utilizing the concept extracted in the extraction step.
A program activating a computer as an information search system for carrying out an information search based on a search request from a user, the program setting the computer to execute:
- a first search procedure of searching a folksonomic ontology on the basis of the search request;
- an extraction procedure of extracting a concept from a library ontology in relation to an acquired concept through searching the folksonomic ontology;
- and
- a second search procedure of searching the library ontology by utilizing the concept extracted in the extraction procedure.
An information search service provision method for carrying out an information search based on a search request from a user and providing a result to the user, the method comprising:
- a first search step of searching a folksonomic ontology on the basis of the search request;
- an extraction step of extracting a concept from a library ontology in relation to an acquired concept through searching the folksonomic ontology;
- a second search step of searching the library ontology by utilizing the concept extracted in the extraction step;
- a pathfinder creation step of creating as a clue for the information search a pathfinder at least having a search result from the first search step and a search result from the second search step;
- and
- a pathfinder provision step of providing the created pathfinder to the user.
