Detailed Instructions: 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.
See one example below:
Problem: Context: 'That sounds pretty reasonable as I am in need of firewood the most. Would it be most reasonable to each take what we need most and split the water down the middle?' 'Yes, it would.' 'I think that sounds fair. The problem is that there are 3 waters and one of us would get two and the other one. How should we sort that?'
Utterance: 'You can take the two water. I am not that thirsty most days.'
Solution: No
Explanation: In this utterance, the participant does not use self-need since they do not talk about any need for themselves.

Problem: Context: 'Ok perfect, the item I need the most is water because I need to hydrate.  What do you think if I give you 2 food and I keep 2 of water. ' 'Ii understand , the problem  is ctheere is 3 of us. What if  we have 2 food and 2 water and you have 2 firewood ?🙂' 'The object I need the most is WATER, so I cannot give you 2, I am giving you 2 FOOD since it is what you most need. Remember that we must both be satisfied for this to work🙂'
Utterance: '(sorry for the misspellings on above post, my keyboard does that) Ok since that  is your highest priority , I have 2 food 1 water and 2 firewood ? Is that agreeable ?🙂'
Solution:
No
