Proposed Model for Context Topic Identification of English and Hindi News Article Through LDA Approach with NLP Technique

Abstract

According to the survey, India has the world's second-largest newspaper market, with more than 100�K newspaper outlets, approx 240 million circulation, and 1300 million subscribers or readers. The topic modeling work is increasing day by day, and researchers have published multiple topic modeling papers and have implemented them in different areas like software engineering, political science and medical, etc. LDA topic modeling is used in this research because it has been introduced successfully for topic modeling and classification and it measures the probability of a text-dependent on the bag-of-words scheme without considering the word series. LDA is a common topic modeling algorithm with excellent implementation in the Gensim Python package. However, the challenge is how to extract good quality topics that are simple, separated, and meaningful. The purpose of this research deals with finding the main topics of the same category news articles which are in two different languages (Hindi and English) and then classifying these different language news topics with similarity measurement. In this research, the corpus is constructed with bigram. To achieve the research goal, we have to first build a headline and link extractor that scrap the top news from Google News feeds for both English and Hindi languages (Google News collects news stories that have appeared on different news website which is already accessible in 35 languages over the last 30�days) and then analyses which two news headlines are similar. � 2021, The Institution of Engineers (India).
