Exploring the learning mechanism of web-based question-answering systems and their design

In recent years, a number of models concerning question-answering (QA) systems have been put forward. But many of them stress technology and neglect the research of QA itself. In this paper, we analyse the essence of QA and discuss the relationship between technology and QA. On that basis, we propose that when designing web-based QA systems, more attention should be paid to the learning mechanism involved in the QA process than to technology. Some new ideas on the design of QA systems are also put forward in order to promote the rapid development of web-based QA systems
