融合MacBERT和Talking⁃Heads Attention实体关系联合抽取模型

针对现有的医学文本关系抽取任务模型在训练过程中存在语义理解能力不足,可能导致关系抽取的效果不尽人意的问题,文中提出一种融合MacBERT和Talking⁃Heads Attention的实体关系联合抽取模型。该模型首先利用MacBERT语言模型来获取动态字向量表达,MacBERT作为改进的BERT模型,能够减少预训练和微调阶段之间的差异,从而提高模型的泛化能力;然后,将这些动态字向量表达输入到双向门控循环单元(BiGRU)中,以便提取文本的上下文特征。BiGRU是一种改进的循环神经网络(RNN),具有更好的长期依赖捕获能力。在获取文本上下文特征之后,使用Talking⁃Heads Attention来获取全局特征。Talking⁃Heads Attention是一种自注意力机制,可以捕获文本中不同位置之间的关系,从而提高关系抽取的准确性。实验结果表明,与实体关系联合抽取模型GRTE相比,该模型F1值提升1%,precision值提升0.4%,recall值提升1.5%。

语域理论视角下的小学英语听说课情境设计——以PEP《英语》中的Let’s talk板块为例

针对教师在听说课的口语情境设计、语篇分析和课堂实践方面存在的问题,可以从语域理论进行思考。语域指的是与某一情境组成的语场、语旨、语式有关的语义集合。其中,语场、语旨、语式分别指伴随语言进行的社会活动、涉及的任务角色以及语言所采用的符号或修辞手段。PEP《英语》中的Let’s talk板块是典型的听说课。教学时,教师可以关注观察与分析、归纳与判断、迁移与创新三个方面,通过“聚焦语场,挖掘语义;关注语式,重视人文;立意语旨,综合创新”等方式,使听说课教学更具人文情怀,使学生学会学习,实现实践创新,提升思维能力。

论英语书面表达与Free talk的有机融合

在英语学习中,Free talk是说的能力,书面表达是写的能力,二者互相联系又相互促进,要有机融合,才能促进英语水平的有效提高。一、初中英语书面表达现状。在初中英语质量检测中,学生词汇贫乏、句型单一、结构松散、逻辑混乱的问题普遍存在。第一,受母语的影响导致汉语式英语,类似“I by bike to school every day”的表达司空见惯。

Talking about Weather

英语中,谈论天气的交际用语很多。如:1.Beautiful day,isn't it?天气真好,不是吗?这是一个省略句,完整的句子是:It's a beautiful day,isn't it?在口语中,谈论天气时还有类似的省略:如:
