Embodiment Construction

[0061] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0062] Such as figure 1 As shown, an automatic composition score calculation method based on sentence fluency, including sentence vector distributed representation, sentence feature extraction, sentence relationship feature extraction, multi-layer perceptron (MLP) model training prediction;

[0063] The sentence vector distributed representation is used to form a sentence representation matrix by different word vector distributed representation methods;

[0064] The sentence feature extraction is used to extract sentence features by convolutional layer and pooling layer;

[0065] The relational feature extraction between the sentences is used to extract the relational features between the sentences through the Self-attention mod...

Abstract

The invention discloses an automatic composition score calculation method based on statement smoothness. The method comprises the steps that S1, expressing sentence vectors in a distributed mode; S2,performing sentence feature extraction; S3, extracting relation features between sentences; and S4, training and predicting a multi-layer perceptron model. According to the method, the statement smoothness index is applied to the field of automatic composition scoring, so that the function of detecting and discovering semantic impaired statements in the composition is realized, and semantic irrelevant words and sick sentences appearing in the composition are scored in a lower degree.

Description

technical field [0001] The invention belongs to the technical field of natural language understanding, in particular to an automatic composition score calculation method based on sentence fluency. Background technique [0002] Structural modeling of coherent text is an important problem in natural language processing. Coherence is a key property of any well-organized text, which evaluates the degree of logical consistency of the text and helps to record a set of sentences in a logically consistent order, which is the core of many text synthesis tasks such as text generation and multi-document summarization. A good essay has a particular high-level logical and thematic structure, and the actual choice of words and sentences and the transitions between them serve to communicate the purpose of the text. Because the concept of coherence is too abstract to capture and measure, it is difficult to explicitly describe the properties of text coherence. Sentence fluency computational...
