1、l 问题点:QoS的管理扩展UDDI的功能简单地讲,就是对原有的UDDI模型进行扩展,一般都不对既存的模型进行修改,而是附加上一些东西(新的角色,中间层次等),使得UDDI也能管理QoS信息,以便更好地为services的用户提供服务。Search Keywords: UDDIQoSextend/extension:CSB: The Collection of Computer Science Bibliographies备注:1. 由于这个领域比较新,当前能找到的相关文章比较少;2. 下面的五篇文章只是根据关键字、题目、摘要以及引用次数来挑选的,可能存在全文阅读后发现所选文章价值不大的情况,

9、No documents match Boolean query ABSTRACTWeb services enhance current web functionality byaltering its nature from document to service-oriented. Asthe number of web services increases, it becomesincreasingly important to provide a scalableinfrastructure of Registries that allows both developersand e
10、nd-users to perform discovery of semantic webenabled services. The discovery of services needs to bebased on QoS characteristics in order to enable resultranking and service selection. Current web servicepublication and discovery mechanisms, such as UDDI,either address these issues partially or not
11、at all. In thispaper, we build on the enabling technologies of WebServices, Peer-to-Peer and Semantic Web in an attempt toaddress all these important dimensions of servicepublication and discovery. More specifically, we use ahybrid peer-to-peer topology to organize Registries basedon domains. In suc
12、h a model, each Registry retains itsautonomy, meaning that it can use the publication anddiscovery mechanisms as well as the ontology of itschoice.3.

14、ms of XML such as the SimpleObject Access Protocol (SOAP 18) or RemoteProcedure Calls for XML (XML-RPC 20).The success of web services is largely basedon the continuous development of standardsthat ensure interoperability. Among the manystandards developed and widely accepted are:the Web Service Des
15、cription Language (WSDL5), used for describing web services' syntax;and the Universal Description, Discovery andIntegration protocol (UDDI 1), often used asa discovery mechanism for dynamically findingnew services. However, there have beenfewer efforts to describe the interactions betweenclients
16、 and services. This paper focuseson augmenting web service clients as a meansfor determining optimal service providers. Asystem is discussed and analyzed for using theResource Description Framework (RDF 14),the Java Expert Systems Shell (JESS), WEKA21, and the Web Ontology Language (OWL16) to augmen
