摘要 使用边建边用的方法,实现了Web数据空间的模式集成。在模式集成时,提出了一个Web数据空间模式集成的框架,运用组合方法,创建了一个中间模式;同时,为用户提供了Top-k个源数据模式。实验表明该方法通过用户参与可以提高查询的准确率与召回率,Top-k个源数据模式的提供,明显提高了查询的有效性。 With the method of pay-as-you-go, a framework is proposed to create an intermediate schema and a Top-k data source schema, by which the schema integration is realized in Web dataspace. By the way mentioned above, experiments implemented in several real applications show high precision results and recall measurements,meanwhile, query validity is improved by the Top-k data source schema.
