... outperforms the statistical ma- chine translation approach within these settings. 1.1 Related Work The use of statistical machine translation for NLU tasks was firstly proposed by (Epstein et al., 1996). ... (Zhou et al., 2002). In this paper we present two approaches for an- alyzing the semantics of natural language inputs and discuss their advantages and drawbacks. The first appro...

We further extend this approach in two aspects: 1) a Bayesian decision framework is used; 2) chain continuations straddling across ... seeing a lexical chain start / end at a particular instance is independent of the starts / ends of other chains. As a result, the probability of seeing a sequence of chain starts a...
