AI Technical Summary

Technical Problem

Existing technologies are not very effective in identifying implicit textual relationships in educational texts, especially when dealing with complex technical terms and multidisciplinary knowledge, making it difficult to accurately identify and understand implicit relationships in the text.

Method used

The RoBERTa pre-trained model is used for encoding, and knowledge graph information is introduced by combining the K-BERT model. The semantic vectors of arguments are obtained through the Bi-LSTM model. Following the human understanding process, fine-grained cue scores are calculated, a multi-angle cue matrix is ​​constructed, features are extracted using a convolutional neural network, and finally implicit text relationship categories are output through the softmax function.

Benefits of technology

It improves the recognition of implicit discourse relationships in educational texts, better understands professional terms and complex terminology, achieves deeper argument interaction representation, and enhances the model's performance in the education field.

Abstract

一种文本隐式篇章关系识别方法、系统、设备及存储介质,方法包括将论元拼接作为输入,使用RoBERTa模型编码,在外部知识融合时使用K‑BERT模型引入知识图谱信息辅助理解论元内实体,之后对两个论元的语义向量进行拆分,使用Bi‑LSTM模型获取包含更多序列信息的各论元整体表示,得到融合了外部信息的论元;仿照人类理解论元关系的过程,对论元间词汇两两配对计算细粒度线索分数,构建得到细粒度多角度线索矩阵;结合整体语义与对当前关系有用的线索特征联合判断关系类别,通过将线索特征与整句语义综合,获取到综合表征,输出关系类别。本发明发掘更深层次的论元交互表征结果,更好地对含义复杂的论元进行判别,提升识别效果。
