| 摘 要： | 为了有效地实现对Web上异构数据源的统一查询处理,提出了一个基于本体的异构数据源集成系统模型OBIISM,引入本体解决各数据源语义层上的异构,通过两级查询重写将用户提交的查询转化为对数据源的查询,为查询异构数据源提供了一个语义统一的接口.

| Abstract: | To help query processing,an Ontology-Based Information Integration System Model(OBIISM) was proposed,it used ontology to resolve the problem of semantic heterogeneity between different data sources,and rewrote a query from user to queries over the data sources through two query rewriting algorithms.Then gave users a global view of heterogeneous data sources. |

| Keywords: | heterogeneous data source semantic information integration query decomposition |
