Abstract:
1. A computer-implemented method of ranking a plurality of products comprising at least a first product and a second product, the method comprising: obtaining a numerical user score for each of the plurality of products; obtaining written user reviews pertaining to one or more of the products; identifying at least one superlative statement from the written user reviews that is determined to include, in terms of product names, only an individual product name and that does not indicate a relative preference between products; identifying written comparison sentiments from the written user reviews by excluding the identified at least one superlative statement from the written user reviews, each written comparison sentiment containing a direct product comparison between first and second products, the direct product comparison including a first product name and a second product name and describing a subjective user preference of the first product relative to the second product; calculating an opinion score for each of the plurality of products, based at least in part on the written comparison sentiments; determining a final score using a computer by combining the numerical user score and the opinion score for each of the plurality of products, wherein a tradeoff parameter is utilized to give a greater weight to the opinion score than the numerical user score in determining the final score; and ranking the plurality of products based on the final score.
