instruction:
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: 'Hi, I need the all food package. I will frequently feel hungry' 'I can give you two of the packages if you're willing to give me all 3 of the firewood. I left mine out in the rain a couple of nights ago so its all ruined.' 'If I will give 2 firewood for you and I will take all the food package with 2 water.'
Utterance: 'I need all 3 firewood! But I'm willing to discuss food with you. I have a lot of that.'
answer:
No


question:
Context: 'I could too, I am a little short on a few things!' 'My biggest concern is water.  I could really use more.  That and some extra food.' 'My biggest concern is food and then water. '
Utterance: 'I'm going to need quite a bit more water, at least 2 packages.  I would like at least 1 food. What do you think?'
answer:
Yes


question:
Context: 'That is so nice of you. Being that you have family, you might need more firewood for cooking for the crew! Do you agree? And how many kids are you traveling with? ' 'I have 2 kids and want to make sure they stay warm.  The firewood will go a long way in keeping them comfortable.' 'I am leaving my little ones home. I feel a little guilty but am going forward with the plan! So, I input our order that you guys receive 3 food, 2 firewood, and no water. Are we in agreement?'
Utterance: 'Yes. That sounds fair to me.'
answer:

No
