#####

In this HIT you will be presented with a partial movie review that acts as a prompt and a system's automatically-generated continuation of that excerpt. Your job is to rate the the system generation across 2 axes:

- Coherence/Quality: Is the system's generation grammatical, easy-to-read and does it follow from the prompt?
- Sentiment: Just considering the completion, how positive is it?

You will be able to rate each of the three axes on a scale from 1 to 5, with 1 being the lowest/worst and 5 the highest/best. The specific scales are:

- Coherence/Quality:
  - 5/5 (excellent): The completion follows effortlessly from the prompt, and is grammatical, fluent, and reasonable.
  - 4/5 (good): The completion makes sense given the input, but there are minor grammatical errors or topical shifts that don't make for the best writing.
  - 3/5 (okay): I can see why this continued from the input, and it's readable, but there are problems that can't be ignored.
  - 2/5 (poor): Some parts of the completion might make sense given the input, but it's unnatural, illogical, or quite hard to read.
  - 1/5 (terrible): The completion completely ignores or contradicts the input, and/or there are severe errors in grammaticality or fluency.

- Sentiment
  - 5/5 (very positive): The completion is glowingly positive.
  - 4/5 (mostly positive): The completion is mostly positive, but there are some imperfections mentioned.
  - 3/5 (neutral): The completion either doesn't represent a positive/negative opinion, or it contains both very positive and very negative aspects.
  - 2/5 (mostly negative): Most of what's expressed here is very negative.
  - 1/5 (scathingly negative): The completion offers a strongly negative opinion.

Note: for rating sentiment, only consider the completion, and not the prompt itself!

### Example 1:

##### Prompt:

I cannot BELIEVE anyone is giving this film a good rating. In addition to the terrible acting, thin (nonexistent?) plot line and slooooooooow pace, this would be the movie to watch if you were really TRYING to fall asleep. The writer's and director's brains must have been fried eggs to ever have concocted something as abominable as this. Based on the

##### System's generation (rate this!):

... director's prior work, however, I have hope for her future films. I think this small misstep is the result of a producer hampering her excellent creativity. There are some shining moments that show her expertise, and I look forward to the director's future films!

- Coherence/Quality: 4/5 Why? The completion recognizes that this movie isn't good (as described in the prompt), and makes a reasonable pivot towards talking about the director's other works. The shift in sentiment is somewhat abrupt, but is well-explained.
- Sentiment: 4/5 Why? The completion recognizes some shortcomings as a pivot, but also, provides a hopeful message for the director's future work.

### Example 2:

##### Prompt:

I cannot BELIEVE anyone is giving this film a good rating. In addition to the terrible acting, thin (nonexistent?) plot line and slooooooooow pace, this would be the movie to watch if you were really TRYING to fall asleep. The writer's and director's brains must have been fried eggs to ever have concocted something as abominable as this. Based on the

##### System's generation (rate this!):

... amazing filmmaking, the film is a must-see for anyone who loves movies. A masterpiece of cinema, great for all ages. I highly recommend this film to anyone. 10/10.

- Coherence/Quality: 1/5 Why? The very positive completion doesn't make any sense given the very negative discussion in the prompt. It contradicts the prompt entirely.
- Sentiment: 5/5 Why? The completion, in isolation, offers only very positive opinions.

### Example 3:

##### System's generation (rate this!):

... other reviews for this film, it seems I'm not alone. Most everyone agrees that this film is a total abomination. The sooner this film is forgotten, the better. A disgusting insult to cinema.

- Coherence/Quality: 5/5 Why? This is a reasonable and grammatical continuation of the very negative review.
- Sentiment: 1/5 Why? This is a scathingly negative review.
