The document summarizes the SWAP research group meeting on April 26, 2010. It outlines the SWOP semantic web service platform and the META multi-language text analyzer. SWOP allows annotating services with natural language descriptions and discovering them through UDDI. META performs analyses on multi-language texts and has a network interface, web interface, and web service interface implemented with Apache Tomcat and Axis2.
