A Knowledge-Based Health Question Answering System

摘要

With the quickly increasing of the Question Answering (QA) corpus, the health QA systems provide a convenient way for patients to provide instant service, and the effectiveness of the answer is a very important and challenging problem to be solved. Therefore, this paper proposes a solution based on medical knowledge base. In the process of generating answers, we utilize the entity set provided by medical knowledge base to calculate the correlation between answers and questions, at the same time we make use of the entities provided by relationships in the knowledge base but not appearing in the answers. Experiment conducted on a real data set in our HealthQA system shows that our method can effectively improve the relevance and accuracy of answer matching by using the medical knowledge base.
