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.

[Q]: Context: 'That would be amazing! So I could take all 3 packages of the food and you could have all 3 packages of the water. Now, we just need to split the firewood. Could I take 2 of the firewood leaving you with 1? I think I would need more for cooking the food. ' 'Awesome! That does sound like a deal. I wish we had more firewood to split because I am afraid it might get cold.' 'I agree. I am feeling generous and I did buy a new axe for this camping trip. So, I could stick to the prior agreement and just work a little harder to find some dry trees to chop.'
Utterance: 'I appreciate your generosity 🙂 I think that bringing your axe would be a great idea! Also be sure to pack warm clothes and extra blankets! I'm sure we will both be fine'
[A]: No


[Q]: Context: 'Hello my friend! Are you ready to go camping?' 'Getting there, just need some more supplies to be safe.' 'Got you! I really need firewood to make smores and I don't think we have enough to last the whole night!'
Utterance: 'I was hoping to pick up a lot of wood. It has rained around here and the wood is soggy in the forest.'
[A]: Yes


[Q]: Context: 'I would love to have the Firewood the most. ' 'Unfortunately I need firewood the most too. How about I take 2 firewood, 2 food, and 1 water?' 'I feel that I am not getting a fair deal. '
Utterance: 'Then what do you think is fair?'
[A]:
No
