Abstract

The invention discloses a judgment method and device of document emotion. The method includes: carrying out sentence recognition on a document to obtain a plurality of sentences; extracting all evaluation objects included in the plurality of sentences; obtaining a score, which corresponds to each evaluation object included by each sentence, on the basis of all the evaluation objects included by the sentence and emotion words corresponding to each evaluation object in the sentence; and obtaining emotion types, which are of the document and correspond to each evaluation object, on the basis of the score corresponding to each evaluation object included by each sentence, wherein the emotion types include one of the following items: positive emotion, neutral emotion and negative emotion. The method solves the technical problem that emotion judgment methods in the prior art are low in accuracy of emotion judgment on the document including the plurality of evaluation objects.

Description

technical field [0001] The present invention relates to the field of natural language processing, in particular to a method and device for judging document emotion. Background technique [0002] Sentiment judgment is one of the key tasks of natural language processing. At present, whether based on vocabulary or corpus, there are many sentiment analysis methods for processing documents, but they are limited by the complex procedures of practical problems and the complex feature sentiment judgment of documents. There is no one-size-fits-all algorithm that can have a good emotional judgment accuracy in various specific problems.
