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: 'Yes, at least 1 of firewood, one of water and one of food.' 'Okay, that would work for me. I'm sure you have good reasons.' 'Do you have a small group, like I do?'
Utterance: 'No, I have a pretty large group, unfortunately, so we need some extra supplies as well.'

A: No

Q: Context: 'I need extra food. I have recently  been ill and my doctor has prescribed extra calories so I can regain my strength.' 'I’m sorry to hear that! If there are 3 packages of food please take 2 of them. I could stand to eat less!' 'Thank you. That deal is perfect!🙂'
Utterance: 'Sounds good to me. Let me see how to execute this trade!'

A: No
****
Q: Context: 'You can take the two water. I am not that thirsty most days.' 'That's very generous of you!🙂 If you are sure, then I am in agreement. So we are saying, I get 3 firewood, you get 3 food and you get one water while I get two water?' 'Yes, I think that is okay.'
Utterance: 'Okay, that sounds fine to me. To me, water is a good substitute for food if I feel hungry. I will submit our agreement then. Thanks for working so amicably. Enjoy your day.'

A:
Yes
