This document discusses opinion mining and sentiment analysis. It begins by explaining how the rise of social media has created opportunities to understand public opinions on various topics by analyzing user comments. It then defines opinion mining as using computational techniques to extract, classify, understand and assess opinions expressed online, with sentiment analysis identifying sentiments in text. The document goes on to provide hardware and software requirements for a proposed system related to these techniques.

AI and Opinion Mining
Abstract
The advent of Web 2.0 and social media content has stirred much excitement and created
abundant opportunities for understanding the opinions of the general public and consumers
toward social events, political movements, company strategies, marketing campaigns, and
product preferences. Many new and exciting social, geopolitical, and business-related research
questions can be answered by analyzing the thousands, even millions, of comments and
responses expressed in various blogs (such as the blogosphere), forums (such as Yahoo Forums),
social media and social network sites (including YouTube, Facebook, and Flikr), virtual worlds
(such as Second Life), and tweets (Twitter). Opinion mining, a sub discipline within data mining
and computational linguistics, refers to the computational techniques for extracting, classifying,
understanding, and assessing the opinions expressed in various online news sources, social media
comments, and other user-generated content. Sentiment analysis is often used in opinion mining
to identify sentiment, affect, subjectivity, and other emotional states in online text.
