医学文献含有丰富的有价值的医学知识。目前,在医学文献上的实体关系提取研究已经得到了很大的进步,但是随着医学文献数量以指数形式增加,医学文本的标注工作成为一个很大的问题。为解决人工标注耗时长、工作量大的问题,研究者提出了远程监督标注的方法,但这种方法会引入大量噪声。本文提出了一种基于卷积神经网络的新型神经网络结构,可以解决大量噪声问题。该模型可以利用多窗口卷积神经网络自动提取句子特征,在得到句子向量后,通过注意力机制选择对真实关系有效的句子。特别地,提出实体类型(ET)嵌入方法,通过加入实体类型特征用于关系分类。我们针对训练文本存在不可避免的标注错误问题,提出句子级别的注意力机制用于关系提取。使用968份糖尿病医学文献进行实验,结果表明,与基线模型相比,本文模型在医学文献中得到了较好的效果,F1分数达到93.15%。最后,我们将提取的11类关系以三元组的形式存储,并利用这些三元组制成具有33347个节点、43686条关系边的复杂关系医学知识图谱。实验结果证明,本文所使用的算法明显优于用于关系提取的最佳基准系统。

Dynamic soil-pile-superstructure interaction is crucial for understanding pile behavior in earthquake-prone ground. Evaluating the safety of piles requires determining the seismic bending moment caused by combined inertial and kinematic interactions, which is challenging. This paper addresses this problem through numerical simulations of piles in different soil sites, considering soil nonlinearity. Results reveal that the period of the soil site significantly affects the interaction among soil, piles, and structures. Bending moments in soft and hard soil sites exceed those in medium soil sites by more than twice. Deformation modes of piles exhibit distinct characteristics between hard and soft soil sites. Soft soil sites exhibit a singular inflection point, while hard soil sites show two inflection points. In soft soil sites, pile-soil kinematic interaction gradually increases bending moment from tip to head, with minor influence from superstructure's inertial interaction. In hard soil sites, significant inertial effects from soil, even surpassing pile-soil kinematic effects near the tip, lead to reversed superposition bending moment. Superstructure's inertial interaction notably impacts pile head in hard soil sites. A simplified coupling method is proposed using correlation coefficient to represent inertial and kinematic interactions. These findings provide insights into complex seismic interactions among soil, piles, and structures.
