Abstract: This thesis focuses on providing a hierarchical structure to organize consumer reviews of products. The hierarchy is generated by a domain-assisted approach which simultaneously exploits domain knowledge (e.g., the product specifications) and the consumer reviews. It organizes product aspects as nodes following their parent-child relations. For each aspect, the reviews and corresponding opinions on this aspect are stored. Such hierarchy facilitates users in understanding the knowledge inherent within the reviews. Also, it provides a well-visualized way to browse consumer reviews at different levels of granularity to meet various users' needs, which can help to improve information dissemination and accessibility. The experimental results on 11 popular products in four domains demonstrate the effectiveness of our approach. We further apply the generated hierarchy to support the application tasks of product aspect ranking, and opinion-QA on products. Significant performance improvements are achieved on these tasks.
