Abstract

QA service is one important service for Telecommunication, while it’s very difficult because of the variety of question formations. This paper designs and implements an automatic QA system based on knowledge base. We first construct a knowledge base using the Entity-Attribute-Value model. We collect the entities, the corresponding attributes and values from a corpus in Telecommunication domain. We analyze customers’ questions, extract entities and attributes from the questions, get the question type to retrieve answers from the knowledge base. The results show our system work well especially for multi-questions.

Keywords
