Research on the Key Algorithms of HNC Question Answering System

HNC Question Answering system(HNCQA)is one of the most brand-new question answering processing pattern. Compared with the traditional QA system, HNCQA penetrate into the language concept space to resolve the understanding problem. Processing in this way can reduce the word sense ambiguity as drastically as possible. This paper will introduce the HNCQA architecture on the whole and present some key algorithms which server the HNCQA in some key positions. The experiment,which we have made, indicates that the system based on the algorithms we designed and provided with a middle scale common-sense knowledge database can get good performance.
