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: 'I am well; I love going camping. I really enjoyed my time in Boy Scouts and look forward to practicing what I learned to good use' 'That is awesome. I brought extra firewood if you need some. My brother forgot to pick up the water when he left town and now is 15 mins away. Do you have any you give?🙂🙂' 'I would love some extra firewood; however I need some extra food too. I have diabetes and it's important that I have more food for later'
Utterance: 'O wow.☹️ I'm sorry to here that. I can give you all my firewood and a food if you can give me all your water. '

Answer: No


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


Question: Context: 'No I was thinking I would get all the waters and you get 1 firewood or I get one food 2 waters and 2 firewood. ' 'We packed enough water but the kids spilled some so I just wanted to make sure we have additional water in case we run out. But we can do with only 1 water. We do really need the food though ☹️' 'So do I. I'm trying to bulk up because I've been skinny all my life. ☹️ Let me just get one please☹️☹️☹️☹️☹️☹️'
Utterance: 'well we do not want to be unreasonable. How about we take 2 food, 2 water then just in case they can be satisfied with the extra water. In that case you get 1 food, 1 water and all firewood. '

Answer:
No
