[Objective] This paper visualizes the text mining process through multi-view collaborative technique, aiming to identify the patterns and insights more effectively. [Methods] Based on the textual word vector matrix, we processed the texts of multi-policy subjects with data cleaning, TF-IDF calculation, vector space model, singular value decomposition and other methods. [Results] We examined effectivenesss of the proposed model with governmental information from Zhongguancun of Beijing during the period of January 2016 to August 2017. [Limitations] The framework could not visualize the single data points of large-scale texts. [Conclusions] Multi-view collaborative visualization is an effective way to interpretate text message.
