Searching for comparison points between two objects from the web

Recently, we have been able to often compare two objects using search engines. However, we often browse high ranked Web pages by search engines, which may give biased information. We propose a method for searching Web pages where two objects are compared using a search engine, extracting comparison points from those Web pages, and showing these points to users. Comparison points are keywords for comparing objects. The proposed method can be used to extract points for efficient comparison by using comparison expressions such as "Liquid Crystal TVs are better ..." and "... than Plasma TVs.", etc.
