: Opinion Mining is a novel and important research topic, aiming to automatically acquire useful opinioned information and knowledge in subjective texts. This technique has wide and many real-world applications, such as e-commerce, business-intelligence, information monitoring, public-opinion poll, e-learning, newspaper and publication compilation, business management, etc. In this paper, we give a definition for opinion mining and then describe the motivation of this research. Afterwards, we present a survey on the state-of-the-art of opinion mining on top of four subtasks: topic extraction, holder identification, claim extraction and sentiment analysis, followed by an overview of several existing systems. In addition, specific analysis on Chinese Opinion Mining is performed. Finally, we provide the summarization of opinion mining research.
