automatic generation of semantic patterns for user-interactive question answering
An automatic method for generation of semantic patterns from free-text questions is proposed in this paper. An evaluation method is also proposed to estimate the suitability of the generated patterns and implemented in our user-interactive question answering (QA) system. Experiments with 5500 questions show that 63.9\% generated patterns are satisfactory in the average.
