摘要

数字阅读现在是孩子们阅读的重要方式。本文从儿童数字阅读的现状、阅读需求和阅读促进方法的研究进展出发,对儿童数字阅读的概念进行了界定。针对BAG模型中实体提取只采用简单匹配方法的问题,本文提出了一种基于参考词的实体提取方法和基于问题相关实体的实体图构建方法。数据集实验验证了该模型的有效性。结果表明,BAG模型在验证集和测试集上分别提高了2.4%和4.1%,证明了改进方法的有效性。基于中心节点的图卷积算法,在中心节点后面的实体图中连接局部子图卷积和全局图卷积,使模型能够同时获取局部和全局信息,增强模型的推理能力。

The Application of Micro-Video Technology in the Promotion of Digital Reading in Children's Libraries Under the Background of Media Fusion
Digital reading is now an important way for children to read. This article defines the concept of children's digital reading based on the current situation, reading needs, and research progress of reading promotion methods. Aiming at the problem that only simple matching method is used for entity extraction in BAG model, this paper proposes an entity extraction method based on reference words and an entity graph construction method based on problem-related entities. Experiments on data sets verify the effectiveness of the model. The results show that the BAG model is improved by 2.4% on the verification set and 4.1% on the test set, which proves the effectiveness of the improved method. Based on the graph convolution algorithm of the central node, the local subgraph convolution and the global graph convolution are connected in the entity graph behind the central node, so that the model can obtain local and global information at the same time and enhance the reasoning ability of the model.
