Techniques are presented for providing misinformation detection in online content. The described techniques can identify instances of misinformation in online content and pass a misinformation result to the user. A misinformation probability analysis can be performed by applying a syntactic analysis and a semantic analysis to detect misinformation with confidence by applying featurization to a URL, text of content referenced by the URL, and metadata associated with the URL using a feature set, the feature set comprising semantic-based features and syntactic-based features, wherein the semantic features and the syntactic features are selected from the group consisting of: sentiment amplifiers, sentiment continuity disruption features, lexical features, keywords, baseline features, speech act, sensicon features, emotion detection on the obtained text, exaggerated language, strong adjectives, heuristics, bag-of-words, objectivity, colloquial-ness score, and semantic difference.

The invention discloses a domain-specific Chinese event extraction method. The method includes: preprocessing, removing redundant tags, clauses and participles form original data information; dictionary building, namely performing artificial analysis of large-scale news corpus, summarizing domain-specific common characters and building a character dictionary; summarizing common expressions of reporting domain-specific events and building a trigger word based sentence pattern dictionary; sentence pattern matching, namely performing sentence pattern matching on a syntax tree according to the sentence pattern dictionary; event element extraction, namely performing character extraction on the syntax tree according to the character dictionary and performing time and place extraction on the syntax tree according to syntactic features of time and place elements. With the method, the difficulty of quickly acquiring Chinese news information in the big data environment is solved, users can get news events related to keywords by entering the keywords themselves through automatic processing, and great convenience is provided for information acquisition.

The invention discloses a sentence trunk extraction method and device based on dependency syntax and a readable storage medium, and the sentence trunk extraction method based on the dependency syntaxcomprises the steps: obtaining a to-be-analyzed sentence, carrying out the dependency syntax analysis of the to-be-analyzed sentence, obtaining a dependency syntax analysis result, and extracting a target sentence trunk corresponding to the to-be-analyzed sentence to perform semantic recognition on the to-be-analyzed sentence. The method solve the technical problem of low sentence semantic recognition accuracy.
