The application belongs to the technical field of false information transmission screening, and specifically discloses a network news false information transmission screening method, which comprises the following steps: screening key evaluation dimensions and determining weights based on historical data, generating evaluation rules, determining a regular or emergency monitoring mode according to the transmission amount increase amplitude of the information to be screened and the number of matched words in a preset keyword library, identifying an initial publishing source through a transmission path, evaluating source authority, content consistency and transmission abnormality in the regular mode and outputting a comprehensive credibility, quickly evaluating and outputting an emergency credibility in the emergency mode, and finally matching the credibility with a warning interval to obtain a warning level; the source authority is evaluated based on source information, the content consistency is determined based on text content, and the transmission abnormality is evaluated based on transmission data, and then the comprehensive credibility is outputted in combination with the evaluation dimension rules, so that multi-dimensional collaborative evaluation of the source, the content and the transmission is realized.

The application provides a WHO element extraction method in an English news scene, which comprises the following steps: cleaning and preprocessing data of network news, combining an article title, a lead and an article theme into one text data, and analyzing a tree structure of the text data; extracting all nouns in all noun phrases from a subtree of the text data tree structure, screening core words, recalling a core word set, calculating a characteristic value of each core word, and extracting a first core word in a sorting result as a final core word; expanding the core word into a complete element text, traversing leaf nodes corresponding to the core word, and finding simple sentence nodes in a parent node direction, connecting all texts from the simple sentence nodes to the leaf nodes and then to intermediate links, and finally generating the element text; and the application realizes extraction of WHO elements on multiple news samples, has high accuracy, can improve a recall rate of core words, and can expand a recall set.
