A Lexical and Machine Learning-Based Hybrid System for Sentiment Analysis

Micro-blogs, blogs, review sites, social networking site provide a lot of review data, which forms the base for opinion mining or sentiment analysis. Opinion mining is a branch of natural language processing for extracting opinions or sentiments of users on a particular subject, object, or product from data available online Bo and Lee (Found Trends Inf Retrieval 2(1–2):1–135, 2008, [1]). This paper combines lexical-based and machine learning-based approaches. The hybrid architecture has higher accuracy than the pure lexical method and provides more structure and increased redundancy than machine learning approach.
