摘要

In this paper we propose a feature selection technique for anaphora resolution for a resource-poor language like Bengali. The technique is grounded on the principle of differential evolution (DE) based multiobjective optimization (MOO). For this we explore adapting BART, a state-of-the-art anaphora resolution system, which is originally designed for English. There does not exist any globally accepted metric for measuring the performance of anaphora resolution, and each of MUC, B~3, ceaf, Blanc exhibits significantly different behaviours. System optimized with respect to one metric often tend to perform poorly with respect to the others, and therefore comparing the performance between the different systems becomes quite difficult. In our work we determine the most relevant set of features that best optimize all the metrics. Evaluation results yield the overall average F-measure values of 66.70%, 59.70%, 51.56%, 33.08%, 72.75% for MUC, B~3, CEAFM, CEAFE and BLANC, respectively.
