Research on the Application of Automatic Scoring System in College English Writing

Abstract

Automatic evaluation system of composition is based on artificial intelligence and natural language technology, through the computer and network to evaluate written composition, and put forward the improvement suggestion of application software, is mainly used in large scale composition test score. In order to promote the application of automatic scoring system in college writing, this paper mainly studies the related issues. The research content mainly includes five aspects: shows the typical automatic scoring system, design the system function, build the evaluation model, put forward the proposals, analyses the application effect. With the constant improvement of the education informatization level, automatic scoring system in college writing teaching must get more and more widely used. Introduction College writing and reading comprehension, oral and listening comprehension are in the equally important position. But because of Dumb English is outstanding, in teaching experts and teachers focus on improve the oral teaching and oral expression ability, writing teaching and writing ability is not valued. In fact, the content of the writing ability is very important, through writing can continuously consolidate knowledge and improve their skills. The actual college writing teaching, the teacher corrects the composition of burden, correcting cycle is long, student writing less volume, directly affects the improvement of students' writing level. Automatic composition evaluation system is achieved by computer and network to evaluate written composition, and put forward the improvement suggestion of application software, is mainly used in large scale composition test scores, has the advantages such as fast and save Labor, to avoid interference with human factors, the review results more objective [1,2]. In order to promote the application of automatic scoring system in college writing, this paper studies the related issues. Typical Automatic Scoring System This is respectively explanation on foreign and domestic typical automatic scoring system [3-7]: Abroad: (1) PEG (Project Essay Grader) is the oldest automatic grading composition software, mainly analyze the writing form, only measure the quality of the language of the composition, application of regression principle of statistics, on the surface of the works of some easy to quantify variables (length, word length, punctuation, and grammar, etc.) as the independent variables, to work the scores as the dependent variable, due to the works by observing some quantifiable factors. (2) IntelliMetric of natural language understanding is to support the essay scoring system, the first to use artificial intelligence, as well as using natural language and statistical techniques, scoring system based on artificial intelligence applications. Text from the perspective of grammatical analysis, the analysis of parts of speech and syntactic relations between each other, a process that helps IntelliMetric give according to the main characteristics of standard written composition score. (3) IEA (Intelligent Essay Assessor) is a kind of automatic scoring system based on latent semantic analysis of composition, main composition analysis of the text content and students in the convey of knowledge, rather than writing style or language. The latent semantic 2nd International Conference on Economics, Social Science, Arts, Education and Management Engineering (ESSAEME 2016) © 2016. The authors Published by Atlantis Press 694 analysis is used in the automatic grading students composition, the happy to score composition with pre-arranged pick-up is viewed as a vector, the vector comparison, be able to get every happy to score the composition and the degree of similarity in content score. Domestic: (1) The Cool Correcting Network, provides composition correcting service, service for university teachers and students, in recent years has expanded to the high school students, through training grade engine, automatically according to the level 4 or level 6, the college entrance examination, and the composition of the examination criteria, to automatically correcting students' composition, grading, and expressed in grammar, diction, non-standard place to give feedback, modify advice to students. (2) The New Horizon College composition automatic scoring system, is a new field of vision composition assessment tools, online learning platform using the university four levels and six levels of writing criteria, set a score of 1 to 15 points, can carry on the automatic grading composition on any subject, calculate the total number of words and give comments. (3) Automatic scoring system, large-scale exam composition by extracting shallow text characteristic, the content of latent semantic analysis, and using the linear regression, scores are obtained. Although the results achieved with human raters high relevance, but because is given priority to with a statistical analysis of the characteristics of shallow, and sample size, scope, limitations, there are a certain distance with practical systems. Functional Design Software function is a software should have the efficiency and effect, software goal through software functions to express and implementation, software function and software is presented to the user directly effect. User through software provides functions to understand, use and evaluation system, through the use of the software functions to complete the operation. Functional requirement is the most important content of requirements analysis. Functional analysis is based on software, form with the results of the model of the software functions, and quantitative or qualitative description of the functions of the software is put forward. Functional design result is expressed in structure. Chart of a rectangular box represents a module, a rectangular box attachment represent the relationship between, is located in the upper rectangle represents module, call in the rectangular box below on behalf of the module. Automatic scoring system has the double function of writing and grading, system function design result is shown in Fig. 1. As shown in Fig. 1 consists of seven main modules, function structure and under each main module contains several sub modules. Briefly describe the main modules are as follows: the Resource center, auxiliary writing for students of all kinds of resources; Collaborative learning, for students to engage in learning activities in the form of cooperation and mutual way; Student writing to students writing and submitting online works; Automatic evaluation, the system automatically works for students to evaluate the information such as the grammar, syntax and discourse; Works of the Teacher evaluation, the Teacher to the student's language ability and pragmatic ability and writing level evaluation; Student query, the Student works online query and evaluation and other related information; Data management, teachers and administrators maintain on the system information [8]. Scoring Model Construction Model is by subjective consciousness in the physical or virtual, constitute the objective in this paper, the morphology and structure of an express purpose of affair, can be a solid model, but also can be a virtual model. Model can help people to recognize and understand some things that cannot be directly observed or complex. Model method is the most powerful, most convenient and most effective method for people to understand and explore the objective world. In scientific research, people with certain scientific method, to establish a suitable model to reflect and take the place of the objective object, and through the research on this model to prompt the objective form, features and nature of objects. Using artificial intelligence technology, especially natural language
