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.

Context: 'I think that sounds fair. The problem is that there are 3 waters and one of us would get two and the other one. How should we sort that?' '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?'
Utterance: 'Yes, I think that is okay.'
No
The speaker simply agrees to the terms of the deal that have been proposed. They do not use any negotiation strategies and are not trying to create a personal need for an item by pointing out that they sweat a lot or anything similar. The answer is therefore 'No'..
