本实验检验了《新视野大学英语》作文自动评分系统的评分效度。实验数据表明：系统自动评分与人工评分之间的相关性较显著;系统评分中高分档的评分准确率较低,其他档的评分准确率较高;内容板块较语言板块、篇章结构板块对作文总体评分的影响显著。系统自动评分与适量的人工参与相结合,系统整体评分与细化的文本特征项相结合有助于提高系统的评分效度。 相似文献

本研究通过应用AntConc3.2.1w和SPSS11.5计算机软件,以中国学习者英语语料库(CLEC)和兰开斯特汉语普通话语料库(LCMC)为基础,并且以本族语者语料库LOB&BROWN为参照,针对CONSE-QUENCE的搭配特点进行量化分析,通过对它使用搭配多样性、类联接等多方面对比分析,进而揭示出中国英语学习者使用CONSEQUENCE语义韵的特点。研究表明,与本族语者相比,中国英语学习者表现出正确使用CONSEQUENCE的消极语义韵的特点。通过对汉语和英语CONSEQUENCE语义韵对比分析,本研究发现:汉语的语言迁移是造成中国英语学习者正确使用CONSEQUENCE语义韵的主要原因。 相似文献

1988年广东省语文高考标准化试验中作文命题及评分的质量如何?我们通过抽取2234份试卷,分别摘抄考生在每条作文上的“内容”、“语言”和“结构”的分数,然后用电子计算机进行了数据处理。结果如下: 从上表中我们可以得到如下信息: 1、在作文的效度方面。考生在作文1的得分与全卷总分的相关为0.64,在作文2的得分与全卷总分的相关为0.71(见最后一行)。经统计检验表明,它们均达到极为显著的水平(P<0.01)。这就是说,考生在这二道作文题上的得分与总分的关系极为密切;或者说考 相似文献

Research on Automated Essay Scoring has become increasing important because it serves as a method for evaluating students’ written responses at scale. Scalable methods for scoring written responses are needed as students migrate to online learning environments resulting in the need to evaluate large numbers of written-response assessments. The purpose of this study is to describe and evaluate three active learning methods that can be used to minimize the number of essays that must be scored by human raters while still providing the data needed to train a modern Automated Essay Scoring system. The three active learning methods are the uncertainty-based, the topological-based, and the hybrid method. These three methods were used to select essays included in the Automated Student Assessment Prize competition that were then classified using a scoring model that was trained with the bidirectional encoder representations from a transformer language model. All three active learning methods produced strong results, with the topological-based method producing the most efficient classification. Growth rate accuracy was also evaluated. The active learning methods produced different levels of efficiency under different sample size allocations but, overall, all three methods were highly efficient and produced classifications that were similar to one another. 相似文献

ABSTRACTThe literature on Automated Essay Scoring (AES) systems has provided useful validation frameworks for any assessment that includes AES scoring. Furthermore, evidence for the scoring fidelity of AES systems is accumulating. Yet questions remain when appraising the scoring performance of AES systems. These questions include: (a) which essays are used to calibrate and test AES systems; (b) which human raters provided the scores on these essays; and (c) given that multiple human raters are generally used for this purpose, which human scores should ultimately be used when there are score disagreements? This article provides commentary on the first two questions and an empirical investigation into the third question. The authors suggest that addressing these three questions strengthens the scoring component of the validity argument for any assessment that includes AES scoring. 相似文献

Automated summary evaluation is proposed as an alternative to rubrics and multiple-choice tests in knowledge assessment. Inbuilt rubric is a recent Latent Semantic Analysis (LSA) method that implements rubrics in an artificially-generated semantic space. It was compared with classical LSA’s cosine-based methods assessing knowledge in a within-subjects design regarding two validation sources: a comparison with the results of rubric scores and multiple-choice tests, and the sensitivity of predicting the academic level of the test-taker. Results showed a higher reliability for inbuilt rubric (from Pearson correlation coefficient .81 to .49) over the classical LSA method (from .61 to .34), and a higher sensitivity using binary logistic regressions and effect sizes to predict academic level. It is concluded that inbuilt rubric has a qualitatively higher reliability and validity than classical LSA methods in a way that is complementary to models based on semantic networks. Thus, it is concluded that new automated summary evaluation approaches such as the inbuilt rubric method can be practical in terms of reliability and efficiency, and, thus, they can offer an affordable and valuable form of knowledge assessment in different educational levels. 相似文献

A Latent Semantic Index (LSI) was constructed from arguments made by navy officers concerning events in an anti-air warfare scenario. A model based on LSI factor values predicted level of domain expertise with 89% accuracy. The LSI factor space was reduced using MDS to five dimensions: aircraft route, aircraft response, kinematics, localization, and an unclassifiable element. Arguments in the localization category were reliably more common among officers with the greatest expertise. Automated classification of arguments into these elements achieved 84% accuracy. LSI may be a useful tool for automating aspects of modeling expertise and diagnosing knowledge deficiencies. 相似文献

五四文学革命,各种文学体裁都在掊击传统与借鉴外国中寻求自身的话语定位。散文也是如此,一面批判桐城古文,要求摆脱古文学束缚,一面向外借鉴英法Essay建立现代散文的话语模式,形成了现代散文的两种风格:重叙事抒情的随笔和重哲理议论的杂感。这也正呼应了英国近代散文的两种风格,就其在当时的发展来看,叙事抒情的“兰姆风”影响更大一些。而重哲理议论的“培根风”在五四之初也得到很大发展。从Es-say对中国现代散文话语建立的影响以及现代散文对这一影响有选择的接受这两个方面来讨论现代散文的话语定位。 相似文献

Automated Essay Scoring (AES) has garnered a great deal of attention from the rhetoric and composition/writing studies community since the Educational Testing Service began using e-rater® and the Criterion® Online Writing Evaluation Service as products in scoring writing tests, and most of the responses have been negative. While the criticisms leveled at AES are reasonable, the more important, underlying issues relate to the aspects of the writing construct of the tests AES can rate. Because these tests underrepresent the construct as it is understood by the writing community, such tests should not be used in writing assessment, whether for admissions, placement, formative, or achievement testing. Instead of continuing the traditional, large-scale, commercial testing enterprise associated with AES, we should look to well-established, institutionally contextualized forms of assessment as models that yield fuller, richer information about the student's control of the writing construct. Such tests would be more valid, as reliable, and far fairer to the test-takers, whose stakes are often quite high. 相似文献
