Your aim is to evaluate a movie review analysis system, the purpose of which is to determine whether a review is globally positive or negative.
For each movie review, such a system outputs one of the following classes: positive and negative.
To perform your evaluation, you collect a large set of reviews and have it annotated by two human annotators. This corpus contains 95% of negative reviews (this 95% ratio is for this first question only and may change in the next
questions).
What metrics do you think are appropriate to evaluate the system on this corpus?
You will get a penalty for wrong ticks.
