In this paper, we propose an unsupervised method to identify noun sense changes based on rigorous analysis of time-varying text data available in the form of millions of digitized books. We construct distributional thesauri based networks from data at different time points and cluster each of them separately to obtain word-centric sense clusters(More)
In this paper, we propose an unsupervised and automated method to identify noun sense changes based on rigorous analysis of time-varying text data available in the form of millions of digitized books and millions of tweets posted per day. We construct distributional-thesauribased networks from data at different time points and cluster each of them(More)

Large textual resources are the basis for a variety of applications in the field of corpus linguistics. For most languages spoken by large user groups a comprehensive set of these corpora are constantly generated and exploited. Unfortunately for modern Indian languages there are still shortcomings that interfere with systematic text analysis. This paper(More)

The dissertation by Maryam Fazel, “Matrix Rank Minimization with applications”, [3], focuses on minimizing ranks over matrices of convex sets which is genrally an NP-hard problem. The work provides a new heuristics for solving Rank Minimization Problem (RMP) for PSD matrices, which contrary to hitherto developed heuristics, do not require an initial point,(More)
