Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0028] Based on the subject cloud map of stepless dynamic evolution of automatic indexing, set corresponding subject terms for a certain field, and filter and index the subject terms in all texts in this field, according to the publishing time sequence of the texts , to make statistics on the statistical status of keywords in this field that changes with time, and display the statistical status of the keywords in the keyword cloud diagram through the font size, color, etc. of the keywords; dynamically display the statistics of the keywords in a chronological order steplessly status cloud.

Abstract

The invention discloses a stepless dynamic evolution theme cloud picture generation method based on automatic indexing. Comprising the following steps: setting corresponding subject terms for a certain field, and screening and indexing the subject terms in all texts in the field; according to the release time sequence of the text, counting the statistical state of the subject terms changing along with time in the field; displaying the statistical state of the subject term in the subject term cloud picture through the states such as the font size and the color of the subject term; realizing stepless change of dynamic display of the theme cloud picture by matching a time axis with a key frame in animation transformation. According to the invention, the theme cloud picture display items with higher quality are generated, the number of the theme word display items used for visualization is smaller, the theme word display items have higher field representativeness, meaning superposition among the theme words and meaningless display items in the field can be reduced, and theme content can be better revealed; and the development condition and change of each subject field can be disclosed more scientifically and carefully.

Description

technical field [0001] The invention relates to the field of data intelligence analysis, in particular to a method for generating a stepless dynamic evolution theme cloud map based on automatic indexing. Background technique [0002] Cloud map is a visualization technology for displaying text or text collection content. It mainly displays high-frequency items through font size and color, and can show the development status of a certain field. At present, according to the different display items, there are mainly two categories: tag cloud map and word cloud map. At present, it relies on the user's tags for analysis, which mainly analyzes the full text. The main problem of the current cloud image technology is that it cannot effectively reveal the subject. On the one hand, there will be many synonyms or close synonyms in the display items, and on the other hand, there are some items that are irrelevant to the field to be analyzed or common items. [0003] In terms of dynamic...
