Abstract

Sentiment analysis is defined as the process of mining of data, view, review or sentence to predict the emotion of the sentence through natural language processing (NLP). The sentiment analysis involve classification of text into three phase “Positive”, “Negative” or “Neutral”. It analyzes the data and labels the ‘better’ and ‘worse’ sentiment as positive and negative respectively. Thus, in the past years, the World Wide Web (WWW) has become a huge source of raw data generated custom or user. Using social media, e-commerce website, movies reviews such as Facebook, twitter, Amazon, Flipkart etc. user share their views, feelings in a convenient way. In WWW, where millions of people express their views in their daily interaction, either in the social media or in e-commence which can be their sentiments and opinions about particular thing. These growing raw data are an extremely high source of information for any kind of decision making process either positive or negative. To analysis of such huge data automatically, the field of sentiment analysis has turn up. The main aim of sentiment analysis is to identifying polarity of the data in the Web and classifying them. Sentiment analysis is text based analysis, but there are certain challenges to find the accurate polarity of the sentence. This states that there is need to find the better solution to get much better results than the previous approach or technique used to find polarity of sentence. Therefore, to find polarity or sentiment of, user or customer there is a demand for automated data analysis techniques. In this paper, a detailed survey of different techniques or approach is used in sentiment analysis and a new technique which is proposed in this paper.

Abstract

With the rapid development of technology, Natural Language processing acts as a technique where machine and human can interact simultaneously. Besides learning a new programming language, human being can rather talk with the machine. However, the non-expert users neither understand any computer command nor have any idea about the underlying technology. For this reason, a new parser, SQL_NL has been developed to convert any Structured Query Language (SQL) query to its corresponding natural language version. The parser is much efficient to produce the results within milliseconds with error detection and debugging capabilities. The output produced by the parser is easily understandable and unambiguous with fast conversion rate.
