Online customer reviews are the best advertisement and/or communication tools for product consistency. Consumers often prefer to do some research before agreeing to buy. Customer ratings are a significant source of knowledge for influencing consumer buying choices in the present. In this paper, we discussed SigmaCR’s aim to explore machine learning techniques and skills, natural language processing and information technology to create an intelligent device that analyses consumer product feedback via the Internet and provides comprehensive product summaries and consumer feelings. It would also be a very practical method for evaluating the power of many recent research projects, including ontology-based knowledge extraction and sentimental analysis.
