Inverting semantic structure of customer opinions expressed in forums and blogs

Abstract: We explore the semantic structure of how opinions on products and services are expressed in blogs and forums. To optimize the efficiency of content delivery, we invert the product-feature structure and propose a specific way to represent the user opinion content in forums and blogs, focusing on user concerns about product qualities and features. The content is subject to inversion so that these concerns become primary entry points for browsing and search. User concern is defined syntactically; semantic and concept structure means for such concerns are developed. The system is subject to preliminary evaluation with respect to coverage, information access efficiency and search accuracy.
