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.

Context: 'ohh that's would be really difficult.However we can still sort things out' 'That is great to hear!🙂 How about you take 2 food, 2 water and 0 firewood? What do you think?' 'uhm.how about i have 3 water 2 foods and zero firewood?'
Utterance: 'Are you willing to budge on one water for me? I have 5 people in my group and they really could use one package of water. It is hot out nowadays. '
No

Context: 'True, 2 firewood and 2 food for you and I'll take 3 waters.' 'that sounds perfect! thank you so much for understand and wish me luck with all of the little rascals im taking. to verify, I will be taking 2 FW, 2 Foods and 0 waters' 'Great Have fun🙂'
Utterance: 'same to you! submitting deal!'
No

Context: 'That seems quite unfair. I really would like my camping trip to be enjoyable.' 'I understand. What part of the deal is unfair to you? You get the majority of the highest priority item (food) and I get the majority of the lower priority items (water and firewood).' 'I will have my two packages of food and only one package of firewood. I do not think I can make one package of firewood last for both of my food. '
Utterance: 'So is your counter that you get 2 packages of food, 0 of water, and 2 of firewood?'

No
