To implement question and answering system effectively, it is important to semantically analyze sentences in text corpus and find an exact answer to the question. In this paper, we suggest high-performance question and answering system that can efficiently extract desired information as triplet from sentence using Tree Pattern Expression(TPE). By using TPE, it is possible to match tree patterns speedy and accurately. In experiment, our question and answering system based on triplet using TPE is more effective than other conventional systems. Especially, our system shows much better performance when combined with triplet extension, named entity tagging and question type classification methods.
