服务发现和服务聚合是新兴的面向服务计算(SOC)领域的两个关键问题。我们提出了一种新的(Web)服务发现技术，该技术考虑了组合多个服务来满足客户查询的需要。该算法利用OWL-S本体，显式返回客户端为达到预期结果而必须执行的原子流程调用序列。当不可能完全匹配时，该算法通过返回部分匹配并通过建议将产生完全匹配的附加输入来提供灵活的匹配。
Service discovery and service aggregation are two crucial issues in the emerging area of service-oriented computing (SOC). We propose a new technique for the discovery of (Web) services that accounts for the need of composing several services to satisfy a client query. The proposed algorithm makes use of OWL-S ontologies, and explicitly returns the sequence of atomic process invocations that the client must perform in order to achieve the desired result. When no full match is possible, the algorithm features a flexible matching by returning partial matches and by suggesting additional inputs that would produce a full match.
