- 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.
- 为了实现数据库元搜索引擎在语义层次上的映射, 采用本体作为信息的组织形式, 并记录本体中没有的新词, 当使用新词的频率超过一定阈值时, 加入到本体库中, 对本体进行扩充.查询过程支持“与”和“或”布尔运算.为了提高系统的映射速度, 特别添加了一个记忆模块, 记录用户近期的查询行为.并在映射过程中自动学习用户的查询兴趣, 以此动态决定实例表的查询顺序.实验证明这些方法可以显著降低系统平均映射时间.
