知识和数据双轮驱动的网络舆情分析技术研究

为应对当前网络舆情的新挑战和舆情分析的精准性要求，需要从大数据的角度研究舆情处理新模式，从知识工程的角度挖掘舆情知识体系。借鉴知识技术和大数据技术在舆情领域的最新研究成果，设计了基于知识和数据双轮驱动的网络舆情分析模型，讨论了模型设计和关键技术。最后以"南海问题"主题舆情为案例，对模型在实际舆论工作中的效用进行了验证，结果显示该模型能够较好地对特定主题舆情进行深度分析和挖掘。

Research on Network Public Opinion Analysis Technology Based on Knowledge Technology and Big Data

In order to meet the new challenge of the network public opinion analysis technology in the big data era.It is necessary to study new models of public opinion deals from the perspective of big data,and to excavate the public opinion knowledge structure from the perspective of knowledge engineering.The paper used the latest research of knowledge technology and big data technology in public opinion field for reference,and designed a network public opinion analysis model based on knowledge technology and big data science.Then discussed the design and key technology of the model,finally verified the actual utility in the work of the public opinion based on the subject "the South China Sea issue" public opinion analysis.The results showed that the model could good for a particular theme public opinion in-depth analysis and mining.
