Modeling and multiway analysis of chatroom tensors
Acar, Evrim, Camtepe, Seyit A., Krishnamoorthy, Mukkai S., & Yener, Bulent (2005) Modeling and multiway analysis of chatroom tensors. Lecture Notes in Computer Science : Intelligence and Security Informatics, 3495, pp. 256-268.
This work identifies the limitations of n-way data analysis techniques in multidimensional stream data, such as Internet chat room communications data, and establishes a link between data collection and performance of these techniques. Its contributions are twofold. First, it extends data analysis to multiple dimensions by constructing n-way data arrays known as high order tensors. Chat room tensors are generated by a simulator which collects and models actual communication data. The accuracy of the model is determined by the Kolmogorov-Smirnov goodness-of-fit test which compares the simulation data with the observed (real) data. Second, a detailed computational comparison is performed to test several data analysis techniques including svd , and multi-way techniques including Tucker1, Tucker3 , and Parafac .
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
