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%。

A Study of the Effect of Sichuan Opera Singing on the Vocal Skills of Music Students

The purpose of the article is to explore the effects of Sichuan opera singing on music majors’vocal skills,focusing on three key aspects:pitch test,assessment of rhythmic perception,and emotional expression.Through a quasi-experimental design,100 music majors were selected as research subjects and divided into an experimental group that received Sichuan opera singing instruction and a control group that received traditional vocal instruction.The results showed that compared with the control group,the experimental group receiving Sichuan opera singing teaching showed significant improvement in pitch mastery,rhythm perception,and emotional expression.

Three-talk决策模式干预对急性脑梗死病人神经功能恢复和心理状态的影响

目的:探讨Three-talk决策模式干预对急性脑梗死病人神经功能恢复和心理状态的影响。方法:选取急性脑梗死病人80例,随机分为对照组和观察组,各40例。对照组给予常规护理,观察组在常规护理基础上给予Three-talk决策模式(包括团队会谈、选择会谈、决策会谈)干预,比较2组病人干预前和干预1个月后的负性情绪、肢体肌力、运动功能、吞咽功能和自我护理能力(ESEA)评分。结果:干预前,2组病人焦虑、抑郁、肢体肌力、运动功能、吞咽功能和ESEA评分差异均无统计学意义(P>0.05);干预1个月后,观察组焦虑、抑郁和吞咽功能评分均明显低于对照组(P<0.01),肢体肌力、运动功能、ESEA评分均明显高于对照组(P<0.01)。结论:Three-talk决策模式干预有助于缓解急性脑梗死病人的焦虑、抑郁情绪,帮助病人实现肢体肌力、运动及吞咽功能的恢复,进而提高其自我护理能力。

Progress on research and mitigation of wind-blown sand risk in Dunhuang Singing Sand Mountain and Crescent Spring Scenic area,China

The Singing Sand Mountain and Crescent Spring Scenic Spot in Dunhuang,Northwest China is a world-renowned desert attraction that is also an integral component of the Dunhuang UNESCO Global Geopark.This scenic area underwent a 30-year transformation,i.e.,from a severe sand risk with spring water threatened by sand burial due to dune deformation,to restoration of the original sand flow field and mitigation of the sand burial problem.The current paper summarizes the research on the intensive monitoring of the dynamic change of star dunes near the spring,observation of wind and sand flow movement,and then restoring the harmonic vibration of the sand particles(singing sand)that were previously silenced.The existing and prospective impacts of anthropogenic and natural forces on the deformation of the sand dunes are investigated by integrated methods,guiding the implementation of mitigating measures with significant ameliorative effects.Contrast to common sand control practices that aim to reduce wind speed and stop blown sands,our research highlights the importance of maintaining the natural wind flow field in stabilizing surrounding dunes.These mitigation measures consist of removing excessive vegetation and newly constructed buildings to recover the original wind flow field and sand transport activity.Such research and mitigation efforts ensure the scientific protection and restoration of the special desert landform,and contribute to the mutual enhancement of the conservation and exploitation of this desert scenic spot and similar sites.

The Destruction of Diasporic White Individuals’Sense of Identity in The Grass is Singing

The importance of diaspora identity has grown in recent years as the world becomes more interconnected and diaspora individuals are increasingly involved in matters among different ethnics.The Grass is Singing by Doris Lessing is considered one of the most outstanding works of literature after World War II.Interest in ethnic identity has been heightened.The book is recognized as an introspective reflection of the spiritual crisis suffered by diaspora people and societal crises of the time.The thesis will examine the oppression imposed by dominant white group by exploring the transformation of diasporic white individuals’identity.

HMM-Based Photo-Realistic Talking Face Synthesis Using Facial Expression Parameter Mapping with Deep Neural Networks

This paper proposes a technique for synthesizing a pixel-based photo-realistic talking face animation using two-step synthesis with HMMs and DNNs. We introduce facial expression parameters as an intermediate representation that has a good correspondence with both of the input contexts and the output pixel data of face images. The sequences of the facial expression parameters are modeled using context-dependent HMMs with static and dynamic features. The mapping from the expression parameters to the target pixel images are trained using DNNs. We examine the required amount of the training data for HMMs and DNNs and compare the performance of the proposed technique with the conventional PCA-based technique through objective and subjective evaluation experiments.

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。

基于Viseme的连续语音识别系统及Talking Head

为实现听觉/视觉驱动的说话人头部动画,该文给出了一个基于viseme(说话时的基本嘴形单位)的连续语音识别系统。它训练viseme隐马尔可夫模型(HMM),识别语音为viseme图像序列。建模采用triseme的概念来考虑viseme的上下文相关性,但它需要超大量的训练数据。该文根据viseme图像及其相似度权值(VSW)定义视觉问题集,用来建立triseme决策树,以实现triseme的状态捆绑及HMM参数共享。为比较系统性能,基于phoneme(听觉领域的语音基本单位)的语音识别结果也被映射为viseme序列。在评价准则上,定义viseme图像相似度加权识别精度,更全面地考虑输出和参考图像序列的差别,并用嘴形圆度和VSW曲线中的突变点来评估所得viseme序列的平滑性。结果表明,基于viseme的语音识别系统能给出更平滑和合理的嘴形图像序列。

An Analysis of "the Other" and "the Other World" in Doris Lessing's The Grass Is Singing

The term "Other" is a key concept in the framework of postcolonialism.This paper attempts to analyze the native black people's role-"the Other" in the process of colonization.The British writer Doris Lessing finds the unltimate expression in her first novel The Grass Is Singing.With the settlement of the colonizers,the South Africa has been rendered by the white colonizers as "the Other World" and the native people are regarded as "the Other" who are degraded into unspeakable animals by white people.

巧用Self-talking和课堂设计提高英语口头表达能力

大学英语教学大纲阐明大学英语教学的重点是有效提高学生的实际交际能力。Self—talking对于学生自主学习能力的培养和英语交际能力的提高有着不可忽略的作用。外语学习归根结底是学生自身的学习,课堂是学生语言实践的重要场所。课堂教学不仅要扩大学生的语言知识,加强和提高学生的语言运用能力,还要帮助学生养成良好的自主学习习惯,尤其是Self-talking的自我对话意识和英语表达能力的训练,是对课堂英语口语训练的有益补充。

Jokes on Singing

A ——Why do you sing in the bathtub(浴缸)? ——The door won't lock, so I have to. B ——I've been singing ever since I was two years old. ——No wonder you're hoarse(嘶哑的). C ——Why do you always stand outside on the porch when your wife sings? ——Because I don't want the neighbors to think I'm beating her.

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:

A HMM-based Mandarin Chinese Singing Voice Synthesis System

We propose a mandarin Chinese singing voice synthesis system, in which hidden Markov model(HMM)-based speech synthesis technique is used. A mandarin Chinese singing voice corpus is recorded and musical contextual features are well designed for training. F0 and spectrum of singing voice are simultaneously modeled with context-dependent HMMs. There is a new problem, F0 of singing voice is always sparse because of large amount of context, i.e., tempo and pitch of note, key, time signature and etc. So the features hardly ever appeared in the training data cannot be well obtained. To address this problem,difference between F0 of singing voice and that of musical score(DF0) is modeled by a single Viterbi training. To overcome the over-smoothing of the generated F0 contour, syllable level F0 model based on discrete cosine transforms(DCT) is applied, F0 contour is generated by integrating two-level statistical models.The experimental results demonstrate that the proposed system outperforms the baseline system in both objective and subjective evaluations. The proposed system can generate a more natural F0 contour. Furthermore, the syllable level F0 model can make singing voice more expressive.
