We seek to make QA systems reproducible with shared and modest human effort, carefully separating knowledge from algorithms. To this end, we propose an aesthetically “clean” Bayesian inference scheme for exploiting lexical relations for passage-scoring for QA . The factors which contribute to the efficac y of Bayesian Inferencing on lexical relations are soft word sense disambiguation, parameter smoothing which ameliorates the data sparsity problem and estimation of joint probability over words which overcomes ...展开收缩
