The invention belongs to the technical field of label extraction and particularly relates to a method and a device for automatically generating a Chinese text label cloud. The method for automatically generating the Chinese text label cloud comprises the following steps of a, carrying out word segmentation and part-of-speech tagging on text data to be analyzed by using Chinese lexical analysis; b, extracting a keyword and the word frequency of the text data to be analyzed according to the word segmentation and part-of-speech tagging result; c, taking the extracted keyword and word frequency as input data and generating a label cloud by using a label cloud generation algorithm. According to the method and the device for automatically generating the Chinese text label cloud, which are disclosed by the invention, the Chinese word segmentation and the label cloud algorithm are combined and optimized, the blank of a Chinese word label cloud generation algorithm is filled up and a favorable tool is provided for work such as extraction of key points of news and public opinion analysis.
Description
technical field [0001] The invention belongs to the technical field of label extraction, and in particular relates to a method and device for automatically generating a Chinese character label cloud. Background technique [0002] With the development of science and technology, especially the rapid development of computer technology, the ability of human beings to generate and obtain data has increased by orders of magnitude. Among them, news, the Internet and newspapers generate a large amount of new information. The collection, analysis and mining of these Chinese text data has always been the focus of researchers' work. Labels are usually used to mark text data and calibrate key words, which is convenient. Find or locate. A tag cloud is a visual description of keywords used to summarize user-generated tags or the textual content of a website. The existing tag cloud generation method for Chinese text extracts keywords through the word segmentation technology, and generate...
