TAILIEUCHUNG - Báo cáo khoa học: "An Automatic Generation System for Grammar Tests"

This paper introduces a method for the semi-automatic generation of grammar test items by applying Natural Language Processing (NLP) techniques. Based on manually-designed patterns, sentences gathered from the Web are transformed into tests on grammaticality. The method involves representing test writing knowledge as test patterns, acquiring authentic sentences on the Web, and applying generation strategies to transform sentences into items. | FAST - An Automatic Generation System for Grammar Tests Chia-Yin Chen Inst. of Info.

Chang Dep. of Computer Science National Tsing Hua University 101 Kuangfu Road Hsinchu 300 Taiwan jschang@ Abstract This paper introduces a method for the semi-automatic generation of grammar test items by applying Natural Language Processing NLP techniques. Based on manually-designed patterns sentences gathered from the Web are transformed into tests on grammaticality. The method involves representing test writing knowledge as test patterns acquiring authentic sentences on the Web and applying generation strategies to transform sentences into items. At runtime sentences are converted into two types of TOEFL-style question multiplechoice and error detection. We also describe a prototype system FAST Free Assessment of Structural Tests . Evaluation on a set of generated questions indicates that the proposed method performs satisfactory quality. Our methodology provides a promising approach and offers significant potential for computer assisted language learning and assessment. 1 Introduction Language testing aimed to assess learners language ability is an essential part of language teaching and learning. Among all kinds of tests grammar test is commonly used in every educational assessment and is included in well-established standardized tests like TOEFL Test of English as Foreign Language . Larsen-Freeman 1997 defines grammar is made of three dimensions form meaning and use See Figure 1 . Hence the goal of a grammar test is to test learners to use grammar accurately meaningfully and appropriately. Consider the possessive case of the personal noun in English. The possessive form comprises an apostrophe and the letter 5 . For .
