I wrote earlier this week about Wize a shopping comparison engine that aggregated millions of reviews to compile a “WizeRank” for each product, based on the total number of positive, neutral or negative reviews found on the web.
Today Alex Iskold over on ReadWriteWeb takes a takes a look at Summize, a shopping search engine that also aggregates product reviews from Amazon, but presents product sentiment in a highly visual way using heatmaps. Positive ratings are green, negative are red, with a spectrum of color between them showing how strongly reviewers and consumers feel about a product. Another interesting approach to harnessing the collective opinion of the web to help us make purchasing decisions.
