Question Answering Platform in Network Education

摘要

The communication between the teachers and students is very important in network education. Question-answering system can resolve the problem. This paper proposes a question answering platform in network education and then introduces the kernel module which is the answer extraction based on FAQ and ontology in detail. The paper describes the similarity algorithm between the student question and the question from FAQ and how to build the ontology and how to extract the answer based on the ontology. Experimental results show that the proposed method can achieve good performance and the system is applied.
