An integrated approach to text understanding
Peng Hu, Chaoxuan Shi, Kan Wang, Xingyao Zhang · 2002
Top-down analysis (prediction-based) and bottom-up analysis (syntax and semantics-based) are two typical approaches to text understanding; however, each has its drawbacks. The authors give a novel approach to Chinese text understanding. With the approach, the top-down analyzer (TA) consisting of a predictor and a substantiator is combined with the bottom-up analyzer (BA) which is made up of a syntactic analyzer and an intersentence relation analyzer through cooperation and result synthesis. In text understanding, TA sends predictions to guide BA's bottom-up analysis, and the result synthesizer unites TA's and BA's results into a more complete and detailed result if they are consistent. This approach has been implemented on a distributed knowledge-based system. The preliminary experiments showed that the integrated approach may give a more complete and detailed result than the top-down or bottom-up approaches.>
