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: 'Hmm. Maybe we could go out together on a run. 🙂Always nice to have a running partner. So maybe on the water you get 2, me 1. Then on the Firewood the opposite?' 'That would be fun! I feel like I always do better when I have someone to run against.  Competition does me good. That sounds fantastic on the fire wood and water split.  What is your food situation looking like??' 'How about this? 2 for you and 1 for me. Going low carb and mostly brought my own. What do you think? '
Utterance: 'That sounds great! I don't think my chances for catching any fish are pretty slim!'

Answer: No


Question: Context: 'Why do you have a risk of dehyrdation? Because I believe all people do but I do understand some people are at a greater risk then others. Tell me why you are at risk?' 'I have a medical condition that requires medication, and this medication requires me to drink an extra amount of water or else I will dehydrate. ' 'That is a problem. Does the medication require the use of fire or firewood as well?'
Utterance: 'No, of course not. You can have the extra of those if you'd like. It is really the water that is the most important to me. '

Answer:
Yes
