Scalable Text and Link Analysis with Mixed-Topic Link Models

Many data sets contain rich information about objects, as well as pairwise relations between them. For instance, in networks of websites, scientific papers, and other documents, each node has content consisting of a collection of words, as well as hyperlinks or citations to other nodes. In order to perform inference on such data sets, and make predictions and recommendations, it is useful to have models that are able to capture the processes which generate the text at each node and the links between them. In this paper, we combine classic ideas in topic modeling with a variant of the mixed-membership block model recently developed in the statistical physics community. The resulting model has the advantage that its parameters, including the mixture of topics of each document and the resulting overlapping communities, can be inferred with a simple and scalable expectation-maximization algorithm. We test our model on three data sets, performing unsupervised topic classification and link prediction. For both tasks, our model outperforms several existing state-of-the-art methods, achieving higher accuracy with significantly less computation, analyzing a data set with 1.3 million words and 44 thousand links in a few minutes.Comment: 11 pages, 4 figure

Public Opinion on The New Education Policy 2020

This study identifies education as a factor which manipulates the rural to urban migration observed in the particular areas of the city of Chennai, Madurai and Bangalore and need for the enactment of new education policy. The research was conceded in the same cities because the influence of education from rural-urban in some selected areas can be observed. It was carried out in Madurai, Chennai and Bangalore. Data was gathered by using online interview techniques so that correct and authentic information from the concerned people should be collected. The study reveals that education is the major factor prevailing in today’s society and major pros and cons of the establishment of New Education Policy .The major objectives of the paper are to understand the awareness, perception and impacts of the New Educational Policy of 2020 and To know about the prevailing situation of the Educational policy for determining the practical implications in providing adequate trained staff and resources
