An embodiment of the present invention provides a natural language sentence evaluation method and device, wherein the method includes: obtaining a natural language sentence to be evaluated; extracting sentence quality evaluation features of the sentence, wherein the sentence quality evaluation features include sentence semantic features and \Or sentence description feature, described sentence semantic feature obtains according to the word vector of the words contained in the described sentence, and described sentence description feature obtains according to the structure of described sentence and the content of described sentence; According to the sentence quality of described sentence Evaluate the features and the pre-built sentence quality evaluation model, and obtain the quality evaluation result of the sentence. The present invention proposes the concept of sentence quality evaluation features, through the automatically extracted sentence quality evaluation features and the pre-built sentence quality evaluation model, the quality evaluation results of the sentence can be automatically obtained without manual participation, which greatly improves the sentence evaluation. Efficiency and accuracy also make the evaluation results of sentence quality more objective.
Description
technical field [0001] The invention relates to the field of natural language processing, in particular to a method and device for evaluating natural language sentences. Background technique [0002] In recent years, with the rapid development of information technology, education informatization is also advancing, and the education industry has begun to enter the information age. For example, automatic marking systems are more and more used in various examinations to automatically judge examinees' test papers. Examination papers often include composition, and the automatic evaluation of composition is one of the main difficulties of the automatic marking system. Good-quality composition needs to be supported by high-quality sentences, so when evaluating a composition, it is first necessary to examine the quality of each sentence in the composition , in other words, the evaluation of sentences is the basis for realizing composition evaluation. How to evaluate the quality of...
