Enabling answer validation by logic form reasoning in Chinese question answering

We present a logic approach for answer validation in Chinese question answering (QA). The idea of logic form representation has been used successfully in English QA. Our work extends the LF representation for Chinese. A rule based logic form transformation (LFT) algorithm is introduced and implemented. Lexical knowledge extraction from HowNet for logic proving is discussed. The answer validation algorithm based on LFT is illustrated. An experiment on LFT is performed and reported. Finally, the possibility of cross-lingual QA based on LFT is also prospected.
