QoS-WSC

the QoS-WSC test data-set is introduced and provided for the researchers, to be used for QoS-aware web-services discovery and composition. Service specification files (WSDL files) of this data-set have been generated by injecting QoS index vectors into service specification files of the WSC05 data-set. The injected QoS index vectors have been randomly picked from the QWS ver2.0 data-set. For generating service discovery and composition requests, the QoS importance coefficients vector has also been added to requests available in the WSC05 data-set. The optimal answer is also calculated and recorded for each request.本文向科研人员介绍并提供QoS-WSC测试数据集，该数据集可用于面向服务质量（Quality of Service, QoS）的Web服务发现与组合任务。该数据集的服务规范文件（即Web服务描述语言（Web Services Description Language, WSDL）文件）通过向WSC05数据集的服务规范文件中注入QoS指标向量生成。所注入的QoS指标向量均从QWS ver2.0数据集中随机选取。为生成服务发现与组合请求，本文还向WSC05数据集原有的请求中加入了QoS重要性系数向量。同时，本文为每个请求计算并记录了对应的最优解。
