摘　　要：为使统一检索能够适应当前Internet和异构数据源的不断发展,基于目前流行的Web服务技术,设计了一个异构数据源统一检索框架,并针对检索服务分发和结果融合提出了检索服务统一模型、记录统一模型,以及相应的结果融合算法。结合可扩展标记语言,统一各数据源检索返回的异构数据记录,利用Web服务机制的完好封装性、规范性、松散耦合、高度集成能力等特点,实现异构数据源检索接口的透明集成。基于Web服务的异构数据源统一检索系统实现简单,时空性能好,可扩展性强,能兼顾各数据源的特点实现全局优化。To enable unified search technology adapt to the development of Internet and heterogeneous data source, a framework of heterogeneous data source unified search was designed based on Web services. Search services unified model, records unified model and corresponding results fusion algorithm were proposed for search services distribution and results fusion. Heterogeneous data records were unified expediently by eXtensible Markup Language （XML）, and the global optimization was accomplished by giving attention to character of every data source＇s search interface. Besides, transparent integration to heterogeneous data source＇s search interfaces was archived by taking full advantage of Web services mechanism＇s capability of loose coupling, fine encapsulation, and high-grade integration. Based on this design, heterogeneous data source unified search system could be implemented easily with good spatio—temporal performance.
