互联网已成为人类有史以来的最大“信息集散地”和 “思想自由市场”。其影响力正积聚放大，也成为政府了解民情的直接渠道。习总书记指出：政府要充分反映民意的作用。另一方面，网络民调数据同时包含主观与客观信息等特点，给知识库构建带来巨大挑战。因此，研究网络开源数据的民意调研及知识库不仅能促进信息处理等技术的发展，还能满足国计民生需求。项目拟定以构建网络民意调研知识库体系为研究目标，针对网络民调数据特点与民调应用需求之间矛盾，围绕民调知识库体系、知识协同构建、知识认知推理等3大关键科学问题，开展网络民调的二元知识库体系、知识自适应抽取、知识自主式精化、人机协同的知识渐进获取与更新、多模态集成知识推理等技术研究，期望在5项核心技术取得创新和突破，并在知识获取的精准度与召回率、知识推理的正确性与响应时间、知识库规模等6项技术指标达到国际先进水平；并以雄安智慧城市为主题，构建网络民调应用。

The internet has become the largest "information hub" and "free market of thought" in human history. The influence of the Internet is accumulating and expanding, and it has become a direct channel for government to understand public opinion. Chinese President Xi Jinping pointed out that government management needs to fully reflect public opinion. Internet media contains a wealth of subjective and objective information, which poses a huge challenge to knowledge base construction. Therefore, research on online public opinion and knowledge base construction will not only promote the development of technologies such as information processing, but also meet the needs of the national economy and the people's livelihood. This project aims at the construction and application of knowledge base system oriented to online public opinion survey. To accomplish this goal, this project intends to solve three key scientific problems: design of knowledge base system for online public opinion survey, collaborative knowledge construction, and knowledge cognitive reasoning. In addition, this project plans to achieve innovative breakthroughs in five core technologies: knowledge base system for online public opinion survey, adaptive knowledge extraction technology, autonomous knowledge refinement technology, progressive knowledge acquisition and updating technology under human-machine collaboration, and multi-modal integrated knowledge reasoning technology. Moreover, this project plans to reach international advanced level in six technical indicators, such as precision, recall, accuracy, response time, and knowledge base scale. Finally, we will develop an application for online public opinion survey with the theme of Xiong'an Smart City.
