Enhancing Review Comprehension with Domain-Specific Commonsense
This addresses the challenge of improving online service and product quality through better review comprehension, though it is incremental by building on existing methods like BERT with domain-specific knowledge.
The paper tackled the problem of review comprehension by introducing xSense, a system that uses domain-specific commonsense knowledge bases to enhance performance, achieving state-of-the-art results in aspect extraction and aspect sentiment classification and significantly improving a BERT QA baseline.
Review comprehension has played an increasingly important role in improving the quality of online services and products and commonsense knowledge can further enhance review comprehension. However, existing general-purpose commonsense knowledge bases lack sufficient coverage and precision to meaningfully improve the comprehension of domain-specific reviews. In this paper, we introduce xSense, an effective system for review comprehension using domain-specific commonsense knowledge bases (xSense KBs). We show that xSense KBs can be constructed inexpensively and present a knowledge distillation method that enables us to use xSense KBs along with BERT to boost the performance of various review comprehension tasks. We evaluate xSense over three review comprehension tasks: aspect extraction, aspect sentiment classification, and question answering. We find that xSense outperforms the state-of-the-art models for the first two tasks and improves the baseline BERT QA model significantly, demonstrating the usefulness of incorporating commonsense into review comprehension pipelines. To facilitate future research and applications, we publicly release three domain-specific knowledge bases and a domain-specific question answering benchmark along with this paper.
