Abstract: Methods and systems for providing review based navigation on an ecommerce website are described. The method comprises receiving a user query associated with a specific feature of a product. According to the method, a sentiment analysis of a plurality of reviews associated with the product is performed, along with topic based modeling and contextualization of the reviews by relevance to the query. The analysis may provide a sentiment classification regarding the strengths and weaknesses of each product for that specific feature based on the plurality of reviews associated with the product. The method further provides topic based navigation of the ecommerce website, contextualization of the prior customer reviews, and product relevance. In response to the user query, the contextualized product(s) are displayed to aid the user in selecting a product for purchase.

Abstract: A mail server detects if an incoming message is addressed to multiple recipients, in which case redundant data storage is reduced. A single shared copy of the message is stored, and a reference message, which refers to the shared message, is provided to the addressed recipients. A record of the number of existing reference messages is maintained, and decremented as each reference message is deleted by recipients. When no reference messages remain, the shared message is also deleted. A record of recipients authorized to access the shared message is also maintained, and updated as recipients delete their reference messages.
