SYSTEM AND METHOD FOR AGGREGATING AND SUMMARIZING PRODUCT/TOPIC SENTIMENT
First Claim
1. A computer implemented method for ranking a plurality of products with respect to a topic, the method comprising:
- receiving documents aggregated from multiple online information sources wherein each document contains information on products;
computing snippets of text from the documents, wherein each snippet contains a portion of text describing a product with respect to the topic;
determining an estimate of relevance of each snippet to the topic;
determining an estimate of sentiment of each snippet with respect to the topic; and
determining an aggregate quality score for each products in the plurality of products for ranking the products based on factors associated with each snippet comprising the estimate of relevance of the snippet, the estimate of sentiment of the snippet and the estimate of credibility of the snippet.

Abstract
Documents are collected from a variety of publicly available sources that contain product data including product reviews, product specifications, price information and the like. Snippets of text obtained from the documents are analyzed for relevance, sentiment, credibility and other aspects that help evaluate the quality of a product. Feature vectors are computed for snippets to analyze relevance, sentiment, or credibility. Statistical analysis is performed on the feature vectors to estimate a measure of the relevance, sentiment, or credibility. Factors associated with various snippets are aggregated to compute a quality score for a product or a particular aspect of product including product features, attributes, usages, or user personas. Information is displayed on a user interface that allows the user to examine the details relevant to computation of the quality score.
