对话关系抽取旨在预测对话文本中的实体对之间的关系。在多方对话场景中,由于角色信息的不确定性,传统的实体关系抽取方法面临准确性挑战。针对角色信息不明的问题,模型构建了对话文本异构图,以捕捉多方对话的复杂结构。此外,为了有效处理不同对话轮次中的说话者信息,引入了长短时记忆网络进行特征处理,并将这些特征嵌入到相应的句子节点中。在DialogRE数据集上的实验显示,该模型展现了出色的性能,具体体现在F1和F1c分别达到了66.8%和62.2%,从而验证了其优越性。

1931年,黎锦明发表于《北平晨报》上的歌德纪念文章招致了匿名差评,黎锦明怀疑此事系徐霞村所为,双方由此展开了一场关于“文学创作”和“学术水平”的公开信论争。随着矛盾激化,论争主题由文学理念分歧转向对彼此的人身攻击。此次论争经过舆论发酵引发了不同阶层读者的关注与互动,同时也对双方的文学取向造成了深远影响。黎、徐论争的始末勾勒出近代中国“文学表达”与“报刊公开信”之间的互动图式,呈现了一个“作者、编者、读者”的报刊文学生态系统。

腰椎间盘突出等腰部疾病多由脊柱失稳所致,从该致病成因出发,基于中医“椎曲论”提出一种新型腰部康复机器人。首先,为面向腰部疾病临床康复需求,机器人采用刚柔耦合的结构形式,其主要包括由一组柔性驱动器构成的柔性曲度拟合机构和基于3-PRS并联机构的刚性并联调姿机构,可实现腰椎曲度的精准调节;并基于模块化、小型化设计理念,将各模块紧凑布置,便于在家庭中使用。其次,为确保多柔性驱动器末端拟合曲线的平滑性,计算在不同曲率时各单体驱动器伸长量间的关系。之后,考虑纤维嵌入式气动肌肉的结构特点,建立柔性驱动器的静态数学模型,并基于螺旋理论求解3-PRS并联机构的位置反解。最后,开展柔性驱动器静态特性试验与并联机构运动性能试验,并通过人机交互力与肌电信号的采集、分析,对机器人的康复性能进行评估。结果表明,该腰部康复机器人能够实现预定的康复功能,是一款应用前景良好的腰部康复设备。
