Web服務發現綜述
摘要: Web服務是“1次釋出，到處可用”的新型Internet元件，支援服務複用和組合，對提高網路軟體生產效率和產品質量具有重要意義。Web服務發現是指客戶以某種方式在不同類型的Web服務中找到其想要的服務，以執行Web服務請求。在動態、多樣的Internet服務市場中，發現合適的服務是實現服務共享、複用的重要前提。Web服務發現的效果直接關係服務複用的'質量，影響到服務組合的相容性和可替換性，關係到能否真正實現服務的“即插即用”。Web 服務發現是Web 服務系統架構中的1個重要部分。Web 服務發現的傳統解決方案是UDDI，即基於關鍵詞匹配和簡單分類進行服務發現，但是缺乏對服務質量（QoS）的描述而難以為使用者選擇最佳服務。支援QoS約束的Web服務發現模型— WSDM-Q彌補了這個缺點，但因沒有任何語義資訊，所以不能滿足使用者提出的基於服務功能描述尋找服務的功能。目前基於語義的Web服務發現方案主要是從描述邏輯和本體兩方面，故就基於本體的Web 服務發現進行了探討。

Survey on Web Services Discovery
Abstract : The Web service is “a publication that can be used everywhere” new Internet module， and supports the service multiplying and the combination， to enhances the network software production efficiency and the product quality has the vital significance. The Web service discovery is refers to the customer to find its wish by some way in the different type Web service the service， carries out the Web service dynamic， diverse Internet service market， discovered the appropriate service is realizes service sharing， the multiplying important premise. The Web service discovery effect direct relations service multiplying quality， affects the service combination compatibility and the replaceability， whether relates the true realization service “Plug and play”. The Web service discovery is in a Web service system construction important part， UDDI is one kind of solution. UDDI is carries on the service discovery based on the key word match and the simple classification， but lacks best serves with difficulty to quality of service （QoS） description for the user choice. Supported QoS restraint Web service discovery model - WSDM-Q to make up this shortcoming， because but did not have any semantic information， therefore could not satisfy the user to propose seeks the service based on the service functional description the function. At present，the Web service discovery plan based on semantic mainly is from the description logic and the main body two aspects， therefore on has carried on the discussion based on the main body Web service discovery.
Key words: Web service; Web service discovery; QoS; Semantic Web; description logic; ontology
