摘要:

我们介绍了一个家庭的新的排名算法称为ERank运行在线性/接近线性的时间,并建立在明确建模的网络作为不确定的证据。该模型使用概率论和命题逻辑相结合的概率论证系统(PAS),也是Dempster-Shafer证据理论的一个特例。ERank快速生成NP完全问题的近似结果,使该技术能够在大型网络中使用。我们使用以前介绍的PAS模型的引文网络推广到所有的网络。我们提出了一个统计测试,用于比较不同的排名算法的性能的基础上聚类有效性测试。我们在真实网络上使用该测试进行的实验表明,与PageRank、贴近度和中间度等知名算法相比,ERank具有最佳性能。

英文摘要:

We introduce a family of novel ranking algorithms called ERank which run in linear/near linear time and build on explicitly modeling a network as uncertain evidence. The model uses Probabilistic Argumentation Systems (PAS) which are a combination of probability theory and propositional logic, and also a special case of Dempster-Shafer Theory of Evidence. ERank rapidly generates approximate results for the NP-complete problem involved enabling the use of the technique in large networks. We use a previously introduced PAS model for citation networks generalizing it for all networks. We propose a statistical test to be used for comparing the performances of different ranking algorithms based on a clustering validity test. Our experimentation using this test on a real-world network shows ERank to have the best performance in comparison to well-known algorithms including PageRank, closeness, and betweenness.
