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.

Q: Context: 'i really need water and food. we did not get enough of those.' 'Those are my priorities as well, how about you get all the food and two firewoods, and i get all the water and one firewood, does that sound fair?' 'i would prefer water instead of food if possible, but i am sure we can work it out.'
Utterance: 'water is really important for me, how about i get two waters and three firewoods and you get three foods and one water?'

A: Yes

Q: Context: 'Hello, I am very cold and need food and wood to remain warm. How about I get 3 firewood, 3 food and 1 water?'
Utterance: 'That doesn't really work for me because then I would get only 2 waters and nothing else ☹️. What do you think is your highest priority?'

A: No
****
Q: Context: 'I'd be willing to give you extra food if I could then get extra water and firewood. How about you Get 2 food, 1 water and 1 firewood?' 'That sounds almost fair. But I could possibly use 1 more firewood. What do you think?🙂🙂' 'Idk, you're already getting the extra food which would be important to me. I think my offer is very fair for both of us.'
Utterance: 'I'm not sure either. Well them, how about we switch and you can have 2 food, 1 water, and 1 firewood and I will take the rest. The homeless could use water almost as much as food'

A:
No
