Automated composition of web services by planning at the knowledge level

摘要: In this paper, we address the problem of automated composition web services by planning on their "knowledge level" models. We start from descriptions in standard process modeling and execution languages, like BPEL4WS, automatically translate them into a domain that models interactions among at knowledge level. This allows us to avoid explosion search space due usually large possibly infinite ranges data values are exchanged services, thus scale up applicability state-of-the-art techniques for services. present theoretical framework, implement it, provide an experimental evaluation shows practical advantage our approach w.r.t. not based knowledgelevel representation.
