摘要：
Because the automatic scoring of English assessment is limited by English grammar and semantics, it is not intelligent enough. In order to improve the automatic scoring effect of English assessment, based on computer-aided technology, this study used latent semantic analysis to extract features from English content and identify its specific meaning. Moreover, this paper used the syntax analyzer StanfordParser to analyze the diversity of the sentence structure. In addition, this paper projected the document vector and the word vector into a low-dimensional space by singular value decomposition, so that the compositions that are related to each other can obtain an approximate vector representation even if the same word is not used, and the relevance of the composition context is obtained. Research shows that the method proposed in this paper has certain effects. © 2020, CAD Solutions, LLC. All rights reserved.
