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.

[EX Q]: Context: 'That is really nice of you! I hope they have fun! My family had this trip planned for quite awhile. We have an extra person with us because my son begged me for his friend to come. I couldn't say no. 🙂' 'I have definitely been there before! With taking all the kids I'm worried about them getting dehydrated. I also have a 7 month old that needs water to make her bottles! I was hoping to get 3 extra packaged of water for sure. ' 'That is one of my fears as well. Does you seven month old breast feed? I am hoping for the water as well. I would love to give them to you if I had extra. Is there anything else you need?'
Utterance: 'No they don't ☹️ She is starting to eat a few solid food items. So if I had some extra food that would help. I think if I had 2 waters, 2 food, and 1 firewood to be able to cook and keep things clean I would have enough. '
[EX A]: Yes

[EX 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?'
[EX A]: No

[EX Q]: Context: 'Hi there! I am excited to share these additional camping supplies with you!' 'Yes, same here! I'm glad that we all have our own basic necessities, but extra is always wonderful. 🙂 What are you most interested in?' 'I am most interested in water! My husband and I are traveling with our newborn and we need as much water as possible!🙂'
Utterance: 'Ah, I see! I am in the same boat. We are camping somewhere where there is no source of water and it's very hot. Hm, let's see how to go about this'
[EX A]:
Yes
