在发现、调用和组合活动的自动化中，部署嵌入到Web服务中的语义是一个强制步骤。语义注释是“附加组件”，用于处理实际的互操作性限制，并确保对服务功能的解释提供有效支持。然而，要支持Web服务中的语义并保证准确的功能描述，还需要解决许多问题。早期的努力解决了自动匹配任务，以便找到符合条件的广告服务，适当地满足消费者的需求。在大多数方法中，这一活动通常委托给软件代理，能够驱动推理/规划活动，以发现所需的服务，这些服务可以是单个的，也可以由更多的原子服务组成。提出了一种混合框架，实现了语义Web服务的模糊匹配。中心角色被委托给面向任务的代理，当可用Web服务之间没有精确匹配时，这些代理在给定服务请求时交互以发现近似回复。匹配活动利用数学模型、模糊多集来适当地表示包含在基于OWLS的语义Web服务描述中的多粒度信息。
Deploying the semantics embedded in web services is a mandatory step in the automation of discovery, invocation and composition activities. The semantic annotation is the “add-on” to cope with the actual interoperability limitations and to assure a valid support to the interpretation of services capabilities. Nevertheless many issues have to be reached to support semantics in the web services and to guarantee accurate functionality descriptions. Early efforts address automatic matchmaking tasks, in order to find eligible advertised services which appropriately meet the consumer’s demand. In the most of approaches, this activity is often entrusted to software agents, able to drive reasoning/planning activities, to discover the required service which can be single or composed of more atomic services. This paper presents a hybrid framework which achieves a fuzzy matchmaking of semantic web services. Central role is entrusted to task-oriented agents that, given a service request, interact to discover approximate reply, when no exact match occurs among the available web services. The matchmaking activity exploits a mathematical model, the fuzzy multiset to suitably represent the multi-granular information, enclosed into an OWLS-based description of a semantic web service.
