Journal ArticleDOI
Closed constrained gradient mining in retail databases
TL;DR: A tailored version of CLOSET+, LCLOSET, is first briefly introduced, and a newly proposed weaker but antimonotone measure, top-X average measure, is proposed and can be adopted to prune search space effectively.
Proceedings ArticleDOI
Collective topic modeling for heterogeneous networks
Hongbo Deng,Bo Zhao,Jiawei Han +2 more
TL;DR: Experimental results demonstrate the effectiveness of the joint probabilistic topic model for simultaneously modeling the contents of multi-typed objects of a heterogeneous information network for the tasks of topic modeling and object clustering.
Journal ArticleDOI
Multidimensional Sensor Data Analysis in Cyber-Physical System: An Atypical Cube Approach
Lu-An Tang,Xiao Yu,Sangkyum Kim,Jiawei Han,Wen-Chih Peng,Yizhou Sun,Alice Leung,Thomas F. La Porta +7 more
TL;DR: This paper proposes a novel model of atypical cluster to effectively represent such events and efficiently retrieve them from massive data and shows that the proposed method can provide more accurate information with only 15% to 20% time cost of the baselines.
Proceedings ArticleDOI
ClaimVerif: A Real-time Claim Verification System Using the Web and Fact Databases
TL;DR: ClaimVerif is a claim verification system that not only provides credibility assessment for any user-given query claim, but also rationales the assessment results with supporting evidences, and degrades the score of stances from untrustworthy sources and alleviates the negative effects from rumor spreaders.
Journal ArticleDOI
MiTexCube: MicroTextCluster Cube for online analysis of text cells and its applications
TL;DR: In this article, a new infrastructure called MicroTextCluster Cube or MiTexCube is proposed to support efficient online text analysis on multidimensional text databases by introducing micro-clusters of text documents as a compact representation of text content.
