Abstract

The invention provides a composition off-topic detection method and system. The method comprises the following steps: extracting problem key features from topic sentence codes by a neural network model; extracting key answer features from the composition codes, and inputting the key question features and the key answer features to an attention mechanism layer. It is ensured that the features input to the attention mechanism layer are key features, interference caused by other useless features to data processing of the attention mechanism layer is reduced, and the accuracy of data processing of the attention mechanism layer is improved. On the basis, the attention mechanism layer determines features of subject sentences concerned by the composition and features of the composition concerned by the subject sentences, the features are selected from two directions, the comprehensiveness of the selected features is ensured, the neural network model can perform classification based on more comprehensive features, the accuracy of the classification result is improved, and therefore, the detection accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of digression detection, in particular to a composition digression detection method and system. Background technique [0002] With the development of artificial intelligence technology, more and more jobs can be replaced by machines, for example, composition digression detection can be performed by machines. [0003] Although the composition digression detection by the machine can improve work efficiency, the accuracy of the detection still needs to be improved. Contents of the invention [0004] In order to solve the above technical problems, the embodiment of the present application provides a composition digression detection method and system, in order to achieve the purpose of improving the accuracy of answer text recognition, the technical solution is as follows: [0005] A composition digression detection method, comprising: [0006] Obtaining a topic sentence and a composition correspond...
