摘　　要：提出了一种支持数据源动态加入的交互式数据集成方法.该方法利用基于可视化嵌套表格提供所见即所得的即时集成环境,利用语义映射工具提供半自动化的支持,渐进式地向用户推荐可能的集成结果和方式,屏蔽集成过程的复杂性,并保证任意的数据源引入顺序条件下集成结果的正确性.采用增量式的方法计算新数据源加入时的最优集成方案,利用用户反馈有效地进行剪枝,优化集成过程.通过实验验证了此方法的有效性.A method of interactive data integration was proposed, which could support dynamic data sources incorporation. The method used data service model which could provid a visualized inbeded table as the just-in-time integration environment, and used semantic mapping tool to provide semi-automation support . This approach ensured that random data source introducing order would not affect the correctness of the results. An incremental method was provided to generate optimal integrated solutions when new sources were introduced, and user-feedbacks were used to prune and optimize the subsequent integration process. The experimental analysis proved that the proposed method was valid.
