Online product reviews often mention several aspects of the product. Reviews with multiple aspects are sometimes problematic because some of the aspects mentioned are of little or no relevance to either consumers or providers. Hence, it is important to identify relevant aspects of a product by ranking them in the order of their importance. With that, this chapter introduces a new criterion known as Aspect Relevancy in the process of ranking aspects. The study also incorporates multi-criteria decision-making (MCDM) to recognize vital aspects retrieved from the consumers reviews of products and services. In ranking the selected aspects, the subjective technique for order of preference by similarity to ideal solution (TOPSIS) is employed. The experimental results using Bing Liu and SemEval 2016 Task 5 datasets have demonstrated positive outcome of the proposed approach when compared with two baseline approaches in terms of NDCG@k ranking measure.
