[Purpose/significance] Taking informatics as an example, the paper explores the method and feasibility of mining subject cognition based on social Q&A website. In the meanwhile, through summarizing Zhihu users' knowledge anticipation and subject cognition towards Informatics, it provides special reference for subject building of informatics.[Method/process] Using the essence discussion content under Zhihu's Informatics topic as analysis object, this paper applies clustering analysis and multi-dimensional analysis to discover hotspots, and further analyzes their properties, relationship, core level and other features.[Result/conclusion] Zhihu's hotspots towards informatics can be concludes into seven categories, such as "information retrieval and search engine", and "network marketing and e-commerce", which reflects people's knowledge needs towards Informatics from four perspectives, technology, business, subject and society. Based on this discovery, people's subject cognition towards informatics can be concluded into three dimensions, which are information technology, knowledge application and information society.
