云环境下制造资源和服务需求相似度计算

Similarity calculating based on manufacturing resourceand demand service in the cloud environment

摘要:

针对云环境下的制造资源和服务需求进行本体相似度计算的研究情况,提出一种改进的混合语义相似度算法。该算法针对国内云制造平台下的制造资源和服务需求的特点,将中文短语名称相似度和基于属性相似度相结合,在保证相似度结果准确的前提下,将相似度计算方法拓展到了制造资源和服务需求之间。最后以某云制造平台的部分制造资源和服务需求为例,验证了该方法的有效性。

Abstract:

considering the current research of ontology similarity of manufacturing resource and demand service, modified algorithm based on mixed semantic similaritywas proposed. According to feature of manufacturing resource and demand service on the stage of cloud manufacturing, this algorithm combines Chinese phrases similarity and attribute similarity together. The algorithm we proposed can guarantee the accuracy of similarity results. Besides, this paper expand the similarity computing method into manufacturing resource and demand service. Moreover, real data about manufacturing resource and demand service from one cloud manufacturing resource were calculated to test our new algorithm. Eventually, we verified that this algorithm can calculate the similarity between manufacturing resource and demand service.
