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.

Let me give you an example: Context: 'That sounds pretty reasonable as I am in need of firewood the most. Would it be most reasonable to each take what we need most and split the water down the middle?' 'Yes, it would.' '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?'
Utterance: 'You can take the two water. I am not that thirsty most days.'
The answer to this example can be: No
Here is why: In this utterance, the participant does not use self-need since they do not talk about any need for themselves.

OK. solve this:
Context: '😮Sound good enough but since you know i can not do without having anything to sustain me whenever i am thirsty then i suggest you are free to take TWO of the water and since your food has also been stolen by bears and you don't make much left, then you can have the TWO of the food items too and leave the THREE firewood for me with ONE food. How does that sound? 🙂' 'I think we are getting very close to a good deal. Would you be willing to give me ONE firewood in case the stuff I have gets wet?' 'I strongly agree and shall we call it a deal now? 🙂'
Utterance: 'Like I said, we are close but I really would feel better with just one of the firewood. I'm afraid of not being able to build a fire. If you really need the firewood, however, then I would take one additional item of EITHER the water or food instead.'
Answer:
Yes
