【摘要】 针对Web查询中查询路径分级不精确问题,文中基于RDF和XML技术,通过在语义查询路径上增加语义关联的影响因子,并根据路径上各个实体或属性的影响因子综合计算出一条路径的等级,按照级别高低把查询结果较准确地提供给用户,从而在一定程度上减少用户的分析工作。与一般的分级方法相比,增加语义关联的影响因子后,能够较好地实现基于语义的Web查询。更多还原

【Abstract】 The paper develops IMPACT FACTOR on the searching paths based on RDF and XML in Semantic Web to resolve the imprecision in searching procedure.Based on the intermediate IMPACT FACTOR,a search path’s Rank can be synthetized,and the users will be provided with results which have been better ranked,thus,the users’ tasks will be obviously lessoned.Compare with traditional methods,this technique makes use of IMPACT FACTOR,it can achieve better searching results based on Semantic Web.更多还原
