چکیده

Due to the rapid expansion and heterogeneity of the data, it is a challenging task to discover the trends/paŠerns and relationships in the data, especially from a corpus of texts from published documents, news, and social media. In this paper, we introduce DycomDetector , a novel approach for topic modeling using community detections in dynamic networks. Our algorithm extracts the important terms/phrases, formulates a network of collocated terms, and then automatically re€nes the network on various features (such as term/relationship frequency, sudden changes in their ∗Dr. Tommy Dang is with the Department of Computer Science at Texas Tech University. †Vinh Nguyen is with the Department of Computer Science at Texas Tech University. ‡Md.

Detecting Community and Topic Co-Evolution in Social Networks

In this paper we study how to discover the co-evolution of topics and communities over time in dynamic social networks. We present a topic model-based approach that automatically captures the dynamic features of communities and topics evolution. Our model can be viewed as an extension of the LDA model with the key addition that it can not only detect communities and topics simultaneously but al...
