Accurate analysis of the temporal expression is cru- cial for Korean text processing applications such as information extraction and clmnking for efficient syntactic analysis. It is a complicated problem since temporal expressions often have the ambiguity of syntactic roles. This t)al)er discusses two problenm: (1) representing and identiflying the temporal expres- sion (2) distinguishing the syntactic tim(lion of the temporal exI)ression in case it has a dual syntac- tic role. In this paper, temporal expressions and the context for disambiguation which is called local context are represented using lexical data extracted fiom corlms and the finite state transducer. By ex- periments, it; turns out that the method is eflimtive for temporal expression analysis. In particular, our al)t)roach s...
