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: 'I have a medium amount of water so I would like some more. I wish we had lots of supplies to split up evenly but I'm sure we can work it out🙂' 'I agree! We can figure out working out a deal! What if I gave you 2 food and 2 waters and you gave me your wood and one of food/water? If that doesn't work for you we can also figure something else out.' 'I think that sounds reasonable. Of course, I could counter with I take 2 food, 2 waters and 1 firewood. What do you think of that?'
Utterance: 'That is also good. This is hard to work out since it's uneven haha. What about if I give you all my food, you give me all your firewood, and then I can give you 2 waters? I think that'd be more fair for you. '

SOLUTION: No

PROBLEM: Context: 'My kids are 14 and 12.  So they're fairly independent - but I also know that they want to do a lot of cooking during our camping trip.  Thus, I think that I'm going to need more firewood as I expect that we'll be having a lot of fires while we're out.  How about you?  What are you planning to do on your camping trip?' 'Good ages. They should be able to help out. We're planning to do a big bonfire, maybe some smores, and hopefully find a lake. We're looking for extra firewood and water for the bonfire and to keep hydrated' 'That sounds like a blast.   I would like to propose that you take 2 waters and 1 firewood and I'll take 2 firewoods and 1 water for our respective trips.  Does that work for you?'
Utterance: 'Yes, we are all looking forward to it. Thanks for being amenable and trying to make this work. That might be okay, but could we take take the 3 packages of food? Since we won't be doing as big of a bonfire, I am sure we'll hike more or swim and need the extra energy'

SOLUTION: Yes

PROBLEM: Context: 'i suggest we put excess in charge of working on proposition because prevention of excess is not a good first step.' 'I don't know what you mean by "prevention of excess." Can you clarify?' 'what i mean by prevention of excess is that we should focus on getting excess and not to limit it regardless of what we already have because if we should offer some creative approaches by excess. we can both come to an agreement if you are interested.'
Utterance: 'Okay. Lets just try to do some negotiation. I am the most interested in getting more WATER. The water I already have at the campsite looks dirty so, if it is okay with you, I would like all THREE of them. My food has also been stolen by bears and I don't make much left, so I would like TWO of the food items. You can have all the firewood and the other food item. How does that sound? 🙂'

SOLUTION:
Yes
