Embodiment Construction
[0019] figure 1 It is a flowchart of Embodiment 1 of the event analysis method based on non-negative matrix factorization of the present invention, such as figure 1 As shown, the method includes:
[0020] Step 101. Obtain data to be processed, the data to be processed includes at least one data text;
[0021] Step 102: Perform word segmentation processing on each data text in the at least one data text respectively to obtain a text space matrix corresponding to the data to be processed, the text space matrix describes the text contained in the at least one data text word information;
[0022] Step 103: Perform non-negative matrix decomposition on the text space matrix, determine each event included in the data to be processed and keywords used to describe each event according to the base matrix obtained through decomposition, and determine the The coefficient matrix determines the data texts respectively corresponding to the respective events.
[0023] The method provided ...
