摘要：Twitter is a popular microblogging service where users create tweets which sometimes express opinions about different topics. Sentiment analysis of twitter data is useful for companies that want to monitor the public sentiment of their brands also for consumers who want to research the sentiment of products before purchase. Existing approaches has high complexities, less throughput and consumes more computation time for large dataset. In this paper, we will find polarity of tweets using lazy learning method- K-nearest neighbors classifier. For classification and representing text data when modeling with machine learning we use bag-of-words model here, as it is simple to understand and implement. We performed our experiments using 1.6 million tweets. In order to manage the preprocessed data we are using corpus. Our Experimental evaluations show that our proposed technique is efficient, provides maximum throughput and consumes less time as compared to previous works. We achieve accuracy of 81.1% and specificity of 84.7% of test dataset which is much better than existing approaches.
