Abstract :
This paper proposes a method for understanding time expressions. For components of which time expressions consist, 31 concepts are defined. We provide formal representations for these concepts and proposed an algorithm to analyse the meaning of time expressions. The representation includes both conceptual and quantitative aspects. Experiments for about 2,000 time expressions extracted from actual documents show that the proposed method yields correct interpretation in about 93% of the cases
