TASK DEFINITION: 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.
PROBLEM: 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. '

SOLUTION: No

PROBLEM: Context: '😮Sound good enough but since you know i can not do without having anything to sustain me whenever i am thirsty then i suggest you are free to take TWO of the water and since your food has also been stolen by bears and you don't make much left, then you can have the TWO of the food items too and leave the THREE firewood for me with ONE food. How does that sound? 🙂' 'I think we are getting very close to a good deal. Would you be willing to give me ONE firewood in case the stuff I have gets wet?' 'I strongly agree and shall we call it a deal now? 🙂'
Utterance: 'Like I said, we are close but I really would feel better with just one of the firewood. I'm afraid of not being able to build a fire. If you really need the firewood, however, then I would take one additional item of EITHER the water or food instead.'

SOLUTION: Yes

PROBLEM: Context: 'I can take 2 firewoods, you can take all the food and most of the water. So, I am offering you all the food and water.🙂' 'I suggest you look at my offer because you can get hungry and also need water.i really need the firewood as well' 'We already have more food than we need due to the extra people who brought more food than we'll eat. Plus, we're near a fresh water supply. And there's so much snow, it's insane🙂I need all the firewood. '
Utterance: 'all the firewood will not work for me.okay you can have 2 firewood while i get 1 firewood,3 waterand 3 food'

SOLUTION:
No
