基于本体的机器学习主观答案评价技术

Machine Learning Techniques with Ontology for Subjective Answer Evaluation

Panjab University(旁遮普大学)

M. Syamala Devi, Himani Mittal

摘要:

英语论文的计算机评估是使用机器学习技术,如潜在语义分析(LSA),广义LSA,双语评估替代和最大熵。本体是领域知识的概念图,可以提高这些技术的性能。使用本体使评估过程的整体存在的关键字,同义词,正确的词组合和覆盖的概念可以检查。在本文中,上述技术的实现与本体论和无共同的输入数据组成的计算机科学的技术答案进行了测试。设计并开发了计算机图形学领域本体。用于实现的软件包括Java程序设计语言和工具,如MATLAB,Protégé等。测试使用计算机图形学中的10个问题,每个问题有60个答案。对结果进行了分析,得出了使用本体的结果更准确的结论。

英文摘要:

Computerized Evaluation of English Essays is performed using Machine learning techniques like Latent Semantic Analysis (LSA), Generalized LSA, Bilingual Evaluation Understudy and Maximum Entropy. Ontology, a concept map of domain knowledge, can enhance the performance of these techniques. Use of Ontology makes the evaluation process holistic as presence of keywords, synonyms, the right word combination and coverage of concepts can be checked. In this paper, the above mentioned techniques are implemented both with and without Ontology and tested on common input data consisting of technical answers of Computer Science. Domain Ontology of Computer Graphics is designed and developed. The software used for implementation includes Java Programming Language and tools such as MATLAB, Protégé, etc. Ten questions from Computer Graphics with sixty answers for each question are used for testing. The results are analyzed and it is concluded that the results are more accurate with use of Ontology.
