Reputation and Trustworthiness

Choose an online reputation system (other then Yelp).
Hypothetically, let's say you choose Amazon. Discuss motivations
for leaving feedback. What is the cost of doing so? What
does one gain by doing so? Discuss the costs of leaving deceitful
feedback. Is there a punishment mechanism in the system?
What do we know about the rater of the feedback - their
reputation? Please show examples of ratings and comments
from items in the reputation system.
2. Look at the review for a movie on Rottentomatoes.com.
For example: http://www.rottentomatoes.com/m/rush_2013/
The site has reviews from expert critics and the general
audience. How do the reviews and ratings differ? Are the
reviews aimed at the intended audience?
3. Look online and see if you can find sources of disinformation (as
described in Mitra et al.'s related work section). Did the examples you
found align with their credibility model? Are there other features you
would include in a model to improve credibility detetion accuracy?
