The input is taken from a negotiation between two participants who take the role of campsite neighbors and negotiate for Food, Water, and Firewood packages, based on their individual preferences and requirements. Given an utterance and recent dialogue context containing past 3 utterances (wherever available), output Yes if the utterance contains the self-need strategy, otherwise output No. self-need is a selfish negotiation strategy. It is used to create a personal need for an item in the negotiation, such as by pointing out that the participant sweats a lot to show preference towards water packages.

Question: Context: 'Hi there, good to connect with you. How are you today?'
Utterance: 'I am good, thank you.  What are your preferences? I really need the extra food packages.  We are doing a lot of hiking and mountain biking and there are no grocery stores for at least 50 miles.🙂'

Answer: Yes


Question: Context: 'I agree! We can figure out working out a deal! What if I gave you 2 food and 2 waters and you gave me your wood and one of food/water? If that doesn't work for you we can also figure something else out.' 'I think that sounds reasonable. Of course, I could counter with I take 2 food, 2 waters and 1 firewood. What do you think of that?' 'That is also good. This is hard to work out since it's uneven haha. What about if I give you all my food, you give me all your firewood, and then I can give you 2 waters? I think that'd be more fair for you. '
Utterance: 'Awww thank you! That would be sweet of you. I appreciate it very much and would definitely agree to that deal!'

Answer: No

No
