基于LDA和模糊C均值的Web服务多功能聚类
Web服务 模糊C均值算法 LDA主题模型 Web服务发现
2019/3/13
基于Web服务发现方法通常是将Web服务聚在某一个固定的功能类中，导致该Web服务的其余功能特性被忽略，Web服务的资源利用率降低的问题，提出一种基于LDA和模糊C均值的Web服务多功能聚类方法。首先，从ProgrammableWeb.com网站上爬取Web服务数据，并抽取Web服务描述文档；其次，使用LDA主题模型对Web服务描述文档进行建模，获得包含不同功能信息的文档主题矩阵；最后，在文档主题...
为高效地发现满足用户需求的Web服务，针对Web服务的描述文本较短、缺乏足够有效信息的问题，提出一种基于Word2Vec和LDA主题模型的Web服务聚类方法。该方法首先将Wikipedia语料库作为扩充源，使用word2vec对Web服务描述文档内容进行扩充，再将扩充后的描述文档利用主题模型进行特征建模，将短文本主题建模转化为长文本主题建模，更准确地实现服务内容主题表达，最后根据文档的主题分布矩阵...
基于受限玻尔兹曼机的Web服务质量预测方法
Web服务 服务质量预测 协同过滤 受限玻尔兹曼机
2019/3/12
针对协同过滤算法无法有效处理数据稀疏的问题，提出1种基于受限玻尔兹曼机的Web服务质量(QoS)预测方法；第1阶段使用受限玻尔兹曼机模型对所有缺失的QoS值进行预测，并对原始的QoS矩阵进行填充；在第2阶段基于该QoS矩阵进行全局邻居筛选，同时将受限玻尔兹曼机引入到用户近邻的协同过滤模型中，以预测目标QoS值。研究结果表明：该方法能提高QoS预测精确度，在一定程度上降低数据稀疏对预测的影响。

数字时代隐私和监控的双重困境： 组织传播在Web 2.0时代下的思考
Web 2.0 信息技术 数字时代
2015/9/21
Web 2.0时代的各类信息技术给隐私与监控这两个互相竞争与依存的概念带来了挑战。了解这些挑战必须首先从历史的角度理解这两个概念在东西方的不同解读。其次，随着各类信息技术的发展，现代组织对其成员的监控行为渗透到各个方面，从而导致在工作场所中这两个概念的矛盾日益加深，这一现象值得深入研究。已有相关理论文献及数据报告显示：在数字时代，组织监控的概念需要被重新审视，因为传统意义上的垂直监视呈逐渐扁平化的...
