Baidu (www.baidu.com), as the top Chinese web services company, covers more than 95% of internet users in China. There are more than 4 billion search requests via Baidu every day. The huge quantity of keyword searches on Baidu reflects the genuine needs of Chinese internet users and the characteristics of their information-seeking behaviors. It may also depict the reality of the society, the economy, the culture and people's daily lives in China. In a sense, the search terms on Baidu have become a good reference for the changing trends of social development and public opinion in China.
However, lacking systematic analysis, these search terms may only sporadically reflect the development of Chinese society and thus cannot help scholars see the whole picture and make future predictions. Their potential needs to be further and better explored. Therefore, by utilizing online data mining methods and with cooperation from Baidu Inc., the Public Opinion Research Center at Renmin University of China examined and analyzed search terms on Baidu. We proposed several new indexes, such as the China Social Care Index, China Public Opinion Pressure Index, China Economy Attention Index, People's Well-being Attention Index, China Social Responsibility Attention Index, China Innovation Attention Index, China Social Expectation Attention Index, China Ecological Environment Safety Attention Index, China Financial Safety Attention Index, China Information Security Attention Index, China Population Security Attention Index, China Resources Security attention index, China Public Health Attention Index, and the China Public Security Attention Index. These new indexes delineated the needs and focus of internet users in China.
Dr. Yu and his team studied the top 1000 search terms on Baidu from 2009~2012. His report, Public opinion barometer: How to aggregate and analyze fragmented online information, will summarize the main findings and discuss his experiences in dealing with fragmented information online.
