Research on answer generation method based on focus information extraction

In this paper, the main answer extraction methods applied in automatic question-answer systems are introduced briefly. Then, an answer generating method based on focus information extraction is proposed. In the method, the relations between questions and answers are represented as a matrix. According to the relations, the answer corresponding to a question is generated automatically and returned to users. The experimental results show that the proposed answer extraction method is effective and feasible, which is useful to answer generating module in a question-answer system.
