Sentiment polarity detection in tweets is a more difficult task than sentiment polarity detection in review documents, because tweets are relatively short and they contain limited contextual information. Although the amount of blog posts, tweets and comments in Indian languages is rapidly increasing on the web, research on sentiment analysis in Indian languages is at the early stage. In this paper, we present an approach that classifies the sentiment polarity of Bengali tweets using deep neural networks which consist of one convolutional layer, one hidden layer and one output layer, which is a soft-max layer. Our proposed approach has been tested on the Bengali tweet dataset released for Sentiment Analysis in Indian Languages contest 2015. We have compared the performance of our proposed convolutional neural networks (CNN)-based model with a sentiment polarity detection model that uses deep belief networks (DBN). Our experiments reveal that the performance of our proposed CNN-based system is better than our implemented DBN-based system and some existing Bengali sentiment polarity detection systems.<\/jats:p>","DOI":"10.1515\/jisys-2017-0418","type":"journal-article","created":{"date-parts":[[2018,4,12]],"date-time":"2018-04-12T04:36:54Z","timestamp":1523507814000},"page":"377-386","source":"Crossref","is-referenced-by-count":16,"title":["Sentiment Polarity Detection in Bengali Tweets Using Deep Convolutional Neural Networks"],"prefix":"10.1515","volume":"28","author":[{"given":"Kamal","family":"Sarkar","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering , Jadavpur University , Kolkata-700032 , India"}]}],"member":"374","published-online":{"date-parts":[[2018,3,13]]},"reference":[{"key":"2025120523332152897_j_jisys-2017-0418_ref_001_w2aab3b7b2b1b6b1ab1b6b1Aa","doi-asserted-by":"crossref","unstructured":"M.
