Abstract
One embodiment provides a system for recommending products. The system may include a search engine to retrieve, from a collection of product reviews, product review results using at least two input product names. The system may also include a template builder to build comparative sentence templates to define relationships between at least two product names, in which each comparative sentence template has a weight as a function of the defined relationship, and the search engine extracts one or more snippets matching at least one of the comparative sentence templates within each product review result. The system may further include a review ranking device to rank the product review search results based on the one or more extracted snippets, in which each snippet has a same weight as its matched comparative sentence template.
