Abstract:
In order to implement semantic mapping of database metasearch engines, a system is proposed, which uses ontology as the organization form of information and records the new words not appearing in the ontology.When the new word’s frequency of use exceeds the threshold, it is added into the ontology.Ontology expansion is implemented in this way.The search process supports “and” and “or” Boolean operations accordingly.In order to improve the mapping speed of the system, a memory module is added which can memorize the recent query information of users and automatically learn the user’s query interest during the mapping which can dynamically decide the search order of instances tables.Experiments prove that these measures can obviously reduce the average mapping time.
