Due to the outbreak of COVID-19 school return was postponed, it’s important for university administrators to understand the information demand of college students in time. Based on this we analyze the text of the virtual Question answering community platform to capture the information demand. First we collect questions that raised from January to May 2020 about the topic of college students on Zhihu platform as the initial data set. By using the method of text segmentation and stop words removing us come up with a list of words, then we calculate the TF-IDF value of each words to get the keywords. After then we combine these keywords with the question document to construct the vector space model matrix and using K-means to cluster the documents. After analysing we found that during COVID-19, the information demand of college students mainly include six aspects: study at home, graduating, online examination, employment environment, youth inspiring and postgraduate entrance examination. At the same time, we analyse the changing of specific discussion under each topic. And it is suggested that during the COVID-19 period, universities should improve the psychological adjustment of students, perfect the system of final evaluation of students, and give special care for some rural students.
