中文摘要：

虽然互联网数据对于舆情研判工作具有重大价值，但由于互联网数据的海量、多源、异构等特性，以及数据噪声的存在，使目前的互联网数据处理技术表现出了一定的局限性，影响了互联网数据效用的发挥。大数据分析和计算实验技术能够提升互联网数据在舆情研判中的效用，在实际操作中应注重人的主导作用与技术辅助功能的互动耦合。

英文摘要：

The data on Internet is very useful for the public opinion analysis task. However, due to the massive amounts and the multi-source heterogeneous characteristics, and the noise data on the Internet, current Internet data processing techniques didn＇ t perform well. This situation has severely hampered the data on the Internet to play its effect. Big data analysis and computational experiments technologies can enhance the effectiveness of Internet data in the public opinion analysis task. In practice, we should pay more attention to the interaction between the leading role of human and assistive technologies.
