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: 'I need the food and water.  You can have all the firewood.' 'hello how are you?  I need the food the most because I ran off and left mine sitting on my kitchen counter.  I think we can agree upon you having 2 water but I need 2 food' 'I'm going hiking, and I really need food, it works up an appetite.'
Utterance: 'Well I didn''t bring any with me so I really need two.  I am willing to give you 2 waters.🙂'
answer:
Yes


question:
Context: 'Hey, I am excited to go camping too!  Would you mind sharing your top priority items with me so that we can come up with a fair deal?  Ideally I would love 3 firewoods, 3 foods, and 2 waters just like you aha.  But perhaps we can each get at least 3 packages of our highest priority item ' 'Hmmm, I think I really need the firewood.  I brought softwoods and they burn out quickly so I don't think I'll have enough wood to keep me going through the night. I get kinda scared without the fire.  What is your priority?' 'Okay, well firewood is also my top priority since it will be so cold tonight.  But I would be willing to take only 1 firewood (and give you 2) as long as I got 2 foods and 2 waters '
Utterance: 'Thank you for the offer on firewood.  I think that sounds fair.  However, I really would like at least 2 waters as well. '
answer:
No


question:
Context: 'Hello, I want to keep 3 packages of the water and 2 packages of the food and 1 package of the fire wood , and you can keep 1 package of the food and 2 packages of the firewood.' 'Could I get 1 package of the water just to be entirely safe?? I really appreciate the 2 packages of firewood as it has been very wet and rainy where I will be going.  There will be a lot of standing water, so my chances for having safe water to drink might be a little iffy.' 'Well I planned on spending a few extra days here at this camping site with my family so the extra water will really come in handy for me over the next few days.  I can offer you an extra package of firewood to keep the 3 packages of water.'
Utterance: 'That makes total sense.  I will let you keep all 3 of the water packages.  If I take the extra firewood for all 3 packages then I can probably boil a lot of the water to get the harmful bacteria out.  I really appreciate your generosity 🙂.  '
answer:

Yes
