英语作文自动评分Automatic Essay Scoring in English WritingIntroductionIn recent years, the use of automated essay scoring systems has become increasingly popular in the field of English writing assessment. This technology allows for efficient and objective evaluation of essays without the need for human raters. While some critics argue that automatic essay scoring is not as reliable as human scoring, proponents believe that it can provide valuable feedback to students and teachers alike. This paper will discuss the benefits and challenges of automatic essay scoring in the context of English writing assessment.Benefits of Automatic Essay ScoringOne of the main advantages of automatic essay scoring is its speed and efficiency. With automated systems, essays can be scored within seconds, allowing for prompt feedback for students. This is especially important in educational settings where teachers may have limited time to grade a large number of essays. Additionally, automatic essay scoring is able to provide consistent and unbiased evaluations, as the algorithms used are based on predefined criteria.Furthermore, automatic essay scoring has the potential to enhance learning outcomes by providing students with detailed feedback on their writing. Many automated scoring systems are equipped with features that can identify spelling and grammar errors, as well as provide suggestions for improvement. This feedback can help students understand their strengths and weaknesses in writing, and guide them towards becoming better writers.Challenges of Automatic Essay ScoringDespite its benefits, automatic essay scoring also faces several challenges. One of the main criticisms of automated systems is their inability to assess the content and creativity of an essay. While algorithms can detect spelling and grammar errors, they may struggle to recognize the nuances of language and style. As a result, some argue that automatic scoring cannot fully capture the complexity of human writing.Another challenge of automatic essay scoring is the potential for bias in the algorithms. Research has shown that some automated systems may favor certain writing styles or topics, leading to unfair evaluations. This can be particularly problematic in standardized tests where the stakes are high forstudents. Critics argue that human raters are better equipped to detect and address bias in scoring.ConclusionIn conclusion, automatic essay scoring has the potential to revolutionize the way essays are evaluated in English writing assessment. While there are challenges to overcome, such as bias and limitations in assessing content, the benefits of speed, efficiency, and consistent feedback cannot be overlooked. As technology continues to advance, it is important for educators to critically evaluate the role of automatic essay scoring in enhancing student learning and writing proficiency. By leveraging the strengths of automated systems and supplementing them with human expertise, we can create a more effective and comprehensive approach to assessing English writing.。
机考英语作文格式排版英文回答:Introduction.In the realm of contemporary education, the advent of advanced technology has dramatically transformed the landscape of language proficiency assessments. Machine-based examinations, commonly referred to as machine-assisted language testing (MALT), have emerged as a promising alternative to traditional paper-based tests, offering a range of advantages that cater to the evolving needs of language learners and educators.Body Paragraph 1: Advantages of MALT.One of the primary advantages of MALT lies in its enhanced objectivity and reliability. The machine-driven scoring process eliminates human bias and subjectivity, ensuring that test scores accurately reflect thecandidates' language proficiency. Moreover, MALT's automated grading system can handle large volumes of responses quickly and efficiently, reducing labor costs and minimizing errors.Another significant advantage of MALT is its increased flexibility and convenience. Candidates can take these exams from remote locations at their own pace and time, eliminating the need for physical proctoring. Additionally, MALT platforms often provide real-time feedback, enabling learners to identify areas for improvement and monitortheir progress.Body Paragraph 2: Limitations of MALT.Despite its advantages, MALT also has certain limitations. One concern is the potential for technical difficulties during the exam. Internet connectivity issues or software malfunctions can disrupt the testing process and compromise the candidate's performance. Moreover, MALT exams may be less suitable for assessing certain language skills, such as speaking and writing, which require morenuanced evaluation methods.Another limitation of MALT is its reliance on standardized questions and responses. While this ensures consistency across tests, it may not fully capture the breadth and complexity of language use in real-world situations. Candidates may face difficulties expressing themselves authentically due to the limited question formats.Body Paragraph 3: Implications for Language Learning and Teaching.The emergence of MALT has significant implications for language learning and teaching. On the one hand, it provides educators with a valuable tool for assessing student progress and identifying areas that require additional support. On the other hand, it challenges traditional notions of language assessment and requires educators to rethink their teaching methodologies and adapt to new assessment formats.To fully realize the potential of MALT, language teachers need to incorporate technology into their instruction and prepare their students for the unique requirements of machine-based assessments. This may involve incorporating interactive exercises, simulations, andproject-based tasks that promote authentic language use and encourage critical thinking skills.Conclusion.In conclusion, MALT offers several advantages that make it an appealing option for language proficiency assessments. Its objectivity, flexibility, and convenience aresignificant benefits. However, technical limitations andthe limitations of standardized questions and responses should be considered. As MALT continues to evolve, it is essential for language educators and researchers to explore its potential and develop innovative ways to enhance its effectiveness and address its challenges.中文回答:前言。
英文作文自动评分系统的研究英语写作是学习英语时必须具备的能力之一.更是大规模语言考试中的一种必备题型.随着科学技术的发展,英文作文自动处理系统的建立也逐渐成为现实。
对于英文自动评分系统的建立,首先我们考察的作文评判因素,主要包括词汇句子、错误、发展、词频、例子方面。
其次是对因素的分类与量化,主要运用到了正态标准化、聚类分析、TF词频等方法,得到每项特征因子对应的分数。
并列表展示了出来。
最后就是对每项特征因子权重的赋值,我们主要基于模糊聚类分析技术和粗糙集理论的信息熵原理,对多因素权重分配进行了研究。
标签:自动作文评分正态标准化特征提取TF词频模糊聚类分析信息熵原理一、国内外研究现状.Page是最初几个在自动作文评分领域进行研究的人,他在1966年开发了Project Essay Grader(PEG)系统。
1990年,自然语言处理与信息提取技术取得了很大的进展。
到90年代末,三个新的自动评分系统面世:其一是Intelligent Essay Assessor(IEA ),是在潜在语义分析的基础上开发的一款主要面向文章内容的自动评分系统;另一个是Electronic Essay Rater(E-rater),它结合了自然语言处理和统计技术,能够综合衡量篇章组织、句子结构和内容;还有一个是IntellMetric,是第一套基于人工智能的能够对文章形式与内容进行评分的自动作文评分系统。
另一条研究路线是基于文本分类技术、文本复杂性特征、以及线性回归方法。
类似的还有Rudner and Liang (2002:3-21 )建立的基于统计分析的Bayesian Essay Test Scoring sY stem(BETSY )系统。
与此同时,PEG 在很多方面也得到改进,整合了很多分析器、词典与各种资源,评分效果也得到很大改善。
国内自动作文评分研究仍然不够完善。
其中梁茂成在05年进行了初步的研究。
他以提取浅层文本特征为主,结合针对内容的潜在语义分析,进行线性回归,得到了与人工评分较高的相关度。
收稿日期:2020-11-18 1 研究背景写作自动评分是指利用计算机技术对作文进行评估与计分。
自动写作评估系统的研究可以追溯到20世纪60年代中期,国外作文自动评分技术及应用方面具有代表性的有五种系统: PEG (Project Essay Grade )、IEA (Intelligent Essay Grade )、E-rater 、IntelliMetric 和BETSY (Bayesian Essay Test Scoring System )(梁茂成 等,2007)。
国内的写作自动评价技术的发展也不容小觑,已经广泛应用于英语写作评阅及反馈过程中。
然而,对自动作文评分系统的质疑批评之声一直不断。
当前,社会对自动作文评分最大的质疑就是作文评分是一项非常主观的高级智能活动,而机器实际上是不可能完全理解作文的。
因此,将自动写作评估系统应用到写作教学中的研究出现了三种不同的声音。
第一种声音认为自动写作评估系统通过提供个性化的错误反馈以及语法、拼写、句子和词汇使用的解释说明,给学习者提供了更多的写作实践机会,从而可以提高学习者的写作质量和能力水平(石晓玲,2012)。
智能个性化的写作反馈是有效的。
然而,也有一些研究者对自动评分系统的评价和反馈持否定态度,对自动评分系统的评分标准和原则提出了质疑,认为这样的反馈评价方式“违背了写作中人与人之间交流在线英语写作自动评价系统反馈有效性及优化策略□ 耿娟娟咸阳师范学院外国语学院[摘 要] 在线英语写作自动评价系统已经被越来越广泛地应用在英语写作教学中,为教师和学习者提供个性化的写作反馈。
基于此背景,本研究从反馈信息有效性六大原则,即及时性、正确性、针对性、相关性、多功能性以及可接受性的维度探讨在线英语写作自动评价系统的反馈效度及影响因素,并提出拓展反馈信息维度、构建立体化的评价体系的策略。
