基于全局语义学习的文本情感增强方法研究

为解决弱情感倾向语料影响文本情感分类的问题,提出基于全局语义学习的文本情感增强方法。首先设计语料划分方法,将语料划分为强情感倾向语料与弱情感倾向语料,然后,从文本处理全过程及整体语义学习的角度出发,构造均值抽取与最大值抽取的语义提取方式及文档信息向量,改进基于循环神经网络的变分自编码器的语义学习过程,并用于学习强情感倾向语料中文本的词语序列特征与语义特征。基于此,对弱情感倾向语料进行重构,实现情感增强目标,最后,将经过情感增强的语料替换掉原来的弱情感倾向语料,再进行情感分类模型的训练与测试。结果表明:提出的文本情感增强方法能够提升情感分类效果,并使得Bert分类器对IMDb影评数据集的情感分类精确率达到了93.03%。     

情感因素与大学英语教学

基础英语情感教学策略研究

情感因素是影响外语学习重要因素之一。文章以中、小学英语教学为例,探讨了如何在英语教学中实施情感策略:利用二语习得和外语教学理论知识,帮助学生正确认识英语和英语学习;激发学生英语学习的动机和兴趣,使英语学习成为一种令人愉快的事;尊重学生个体差异,为其创建情感释放的空间;获取学生的认同,培养良好师生关系;实施“蜗牛”计划,确保情感教学持之以恒。     

小学英语教学的情感因素分析

小学英语的教学应充分重视儿童的心理特点,情感因素对于小学英语教学的教学效果好坏起着举足轻重的作用。积极的情感对激发儿童学习兴趣、提高英语教学效果起到积极作用,消极的情感则会影响学生的学习情绪、学习效率,甚至会让儿童产生厌学情绪,为以后的英语学习埋下隐患。     

论学习情感的评价及培养

慕课教学强调自主学习和开放学习,对学习者提出了较高的能力要求。本文从学习者的情感因素出发,以"第二外语"慕课教学设计为例,阐述了学习者的情感因素类别,并通过实证研究探讨了学习者在"第二外语"慕课学习过程中的情感变化,为改变当前慕课高辍学率、低完成率的现状提供参考。     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that
