Sarcasm Annotation

The goal of this annotation task is to determine if a tweet is
sarcastic (SARCASM) or not sarcastic (NOT_SARCASM) as written by the
writer, and assign the corresponding label. While annotating, each
tweet is needed to be judged separately. If the context in the tweet
is not a clear indication, then NOT_SARCASM label should be used. The
annotators are advised to not infer/interpret additional information
that is not given in the tweet.

Notes:

1) Sometimes, a tweet can indicate an equally probable situation, one
being sarcastic and the other being not sarcastic. Without enough
information in the tweet to strongly suggest either, NOT_SARCASM label
should apply. 

2) If sarcasm is clear from the real world knowledge, then SARCASM should be assigned.

3) If hashtag and the tweet statement express contrasting information
indicating the writer is being sarcastic, the tweet should be labeled
as SARCASM. 

4) Humor/jokes are quite different from sarcasm. Many sarcastic tweets
may have intended humor/joke, but the reverse is not always
true. Similarly, sarcastic tweets may sometimes seem angry or
attacking, but the reverse is not always the case. The focus should
always be only on sarcasm, regardless of if it is humorous, attacking
or anything else. Note that not all humorous, attacking, teasing
tweets are sarcastic.

5) Sometimes, it may happen that a very specific part of a tweet may
have opposite indication, but if the main focus/intention of the tweet
is not sarcasm, it should not be labeled sarcastic. These are rare,
but the annotators need to be careful with these situations. For
example: "Stay strong from all the 'tolerant' ones who choose to
personally attack you" - it is quite understandable that "tolerant"
refers to people who are not really "tolerant", but the focus of the
tweet was not sarcasm, rather the call for awareness from a certain
type of people. So, the emphasis here is on "Stay strong", which is
not sarcastic, and the writer truly wanted people to "Stay strong"
from such people. In cases like this, even though the writer is
sarcastic in mentioning a type of people, the message itself is not
sarcastic, and NOT_SARCASM should be assigned to the corresponding
tweet.

6) If there's doubt, and too much inference is required, NOT_SARCASM
label should apply. But always consider the surrounding clues and the
language of the tweet. For example: "So yeah, I'm really feeling the
love tonight.....", the "So yeah", "really" and "....." together
provides some hint towards the case that the writer being is
sarcastic.
