Abstract

The invention discloses a method for automatically generating a nutrition health education video through a commentary file, and further discloses a system for automatically generating the nutrition health education video through the commentary file. The method comprises the steps that keywords in the commentary file are automatically and respectively extracted based on a word frequency statistics method and a knowledge base searching method, all search engines are involved through a meta-search technology to acquire pictures related to the keywords, related pictures in a local picture base are searched through a text searching technology, and line text titles are formed after the commentary file is automatically cut through a word separating technology. The system comprises modules of an automatic keyword extracting module, an automatic picture searching module and a nutrition health education video title background generation module, wherein the automatic keyword extracting module is used for extracting all of the keywords in a section of the commentary file, the automatic picture searching module is used for automatically searching pictures related to the keywords, and the nutrition health education video title background generation module is used for generating the nutrition health education video through texts of each line and related corresponding pictures.

Description

technical field [0001] The present invention relates to the field of multimedia technology, in particular to a method and system for automatically extracting keywords by using commentary documents and searching for related pictures to generate nutrition and health education videos. Background technique [0002] The method and system for fully automatic video generation based on commentary is to search the network or / and local related pictures according to the corresponding words in the text, mainly nouns, but the language characteristics of Chinese itself determine the complexity of its part of speech, which leads to The part-of-speech division is not accurate, and the pictures found are not accurate. Therefore, there are few researches on the method and system of automatically generating videos based on commentary words. Studies have shown that in the field of nutrition and health education, the complexity of sentences is relatively low, and the part of speech is relatively...
