Pay-as-you-go Schema Integration in Web Dataspace

Jiandong Wang

Abstract

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.
