Note: I don't know the techniques used by Microsoft Live/Bing (9/28/2007), but Google has a paper. To see the model, please check out (Hu and Liu, KDD-2004) and (Liu et al, WWW-2005) below, or the books above (better). Try search for a camera and click on reviews. You will see summarized user opinions on product features/aspects in a bar chart.

If you want to be a successful novelist, should you be sentimental in your writing or not?

This work is in the area of sentiment analysis and opinion mining from social media, e.g., reviews, forum discussions, and blogs. In our KDD-2004 paper, we proposed the Feature-Based Opinion Mining model,
which is now also called Aspect-Based Opinion Mining
(as the term feature here can confuse with the term feature used in
machine learning). The output of such opinion mining is a
feature-based opinion summary
or aspect-based opinion summary. The commonly known sentiment classification is a sub-task. Our current work is in two main areas,
which reflect two kinds of opinions (or evaluations)
Mining regular (or direct) opinions. Ex: (1). This camera is great. (2). After taking the drug, I got stomach pain.
Mining comparative opinions. Ex: Coke tastes better than Pepsi.
2. Sentiment Analysis or Mining of Regular Opinions
In this research, we aim to mine and to summarize online opinions in reviews,
tweets, blogs, forum discussions, etc. Specifically, we mine features or aspects of entities (e.g., products) or topics on which people have expressed their opinions and determine whether the opinions are positive or negative. For opinion summarization, we advocate the quantitative aspect and the target of opinions because 50% of the people say something is bad is not the same as 5% say it is bad.
Try Search for the Best Restaurant based on specific aspects, e.g., "best burger," "friendliest service." The system is a demo, which uses the lexicon (also phrases) and grammatical analysis for opinion mining.
Amazon Product Review Data (more than 5.8 million reviews) used in (Jindal and Liu, WWW-2007, WSDM-2008; Lim et al, CIKM-2010; Jindal, Liu and Lim, CIKM-2010; Mukherjee et al. WWW-2011; Mukherjee, Liu and Glance, WWW-2012) for opinion spam (fake review) detection. You can also use it for sentiment analysis. It has information about reviewers, review texts, ratings,
product info, etc. Due to the large file size, you may need to use Download Accelerator Plus (DAP) to download. If you use this data, please cite (Jindal and Liu, WSDM-2008).
Pros and cons dataset used in (Ganapathibhotla and Liu, Coling-2008) for determining context (aspect) dependent sentiment words, which are then applied to sentiment analysis of comparative sentiences (comparative sentence dataset). The same form of Pros and Cons data was also used in (Liu, Hu and Cheng, WWW-2005).
