document: Crawling multiple UDDI business registries As Web services proliferate , size and magnitude of UDDI Business Registries ( UBRs ) are likely to increase . The ability to discover Web services of interest then across multiple UBRs becomes a major challenge specially when using primitive search methods provided by existing UDDI APIs . Clients do not have the time to endlessly search accessible UBRs for finding appropriate services particularly when operating via mobile devices . Finding services of interest should be time effective and highly productive . This paper addresses issues relating to the efficient access and discovery of Web services across multiple UBRs and introduces a novel exploration engine , the Web Service Crawler Engine ( WSCE ) . WSCE is capable of crawling multiple UBRs , and enables for the establishment of a centralized Web services repository that can be used for discovering Web services much more efficiently . The paper presents experimental validation , results , and analysis of the proposed ideas .
