Find opinions on an object

We use product reviews as an example:

Searching for opinions in product reviews is different from general Web search.

E.g., search for opinions on “Motorola RAZR V3

General Web search (for a fact): rank pages according to some authority and relevance scores.

The user views the first page (if the search is perfect).

One fact = Multiple facts

Opinion search: rank is desirable, however

reading only the review ranked at the top is not appropriate because it is only the opinion of one person.

One opinion Multiple opinions
