Chinese Composition Example Sentence Retrieval System Base on Expression

In order to effectively improve the reader's writing ability, this article has established a Chinese composition example sentence retrieval system based on expressions, and relevant composition example sentences can be retrieved according to the writing keywords and expression methods. This article first constructs a expression clause set, and annotates 11 classic expressions such as narration and description. Then it uses the BERT model to automatically identify the expressions, and finally constructs an example sentence retrieval system based on Solr. Experiments show that the performance of example sentence retrieval is better than that of using keywords directly.
