Abstract

The invention provides a tendency analysis method of a public opinion based on word2vec. The method comprises a vector training phase, a key sentence extraction phase and a tendency discrimination phase; by extracting news key sentences, the discriminant feature space is reduced, contents with relatively large relevance with the original theme are remained, useless information is eliminated and the accuracy of tendency analysis of the public opinion is improved; a depth learning model word2vec is introduced into the tendency analysis of the public opinion, and used for comparing the semantic similarity between words and comparing the semantic similarity through word vectors, so that words with the same emotional tendency but not in an emotion dictionary can be well identified, thus even if the emotion dictionary is not complete, a better analysis effect can be obtained, and meanwhile, weighted calculation is performed on the emotional tendency of the key sentences by fusing a grammatical rule; and combined with contextual information, the limitation of simply using the semantic similarity is compensated, and the tendency is analyzed integrally from the sentences, so that the emotional tendency and emotional intensity of news texts of the text level are accurately discriminated.
