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.

Question: Context: 'Well, I think that for us staying warm is more important than having extra food. What if I took extra fire wood and you took extra food?' 'That could work, were not really looking to have a big fire' 'Where do you stand on water? We're low , and may need extra in case the fires go out of control'
Utterance: 'I do need some myself as well'

Answer: Yes

Question: Context: 'Okay I will give you 2 waters. I actually need more of firewood. If I can get 2 I will be glad.' 'Well I really need the firewood because I have small kids with me and it would be hard for me to get some free time to get the firewood, but I would be willing to give you 2 firewood since I get two waters.  What are your thoughts about the food?' 'Okay what about ! firewood and 1 and half water. I don't want to run low on supplies so soon. It will be so bad for me. You can keep your firewood because of the kids.'
Utterance: 'We can't split the water in halves, so we gotta choose.  I need the food packages because I forgot to pack any food and I can't fish.  How about I get 2 water, 1 firewood, and 2 food?  Can we agree on that?'

Answer:
Yes
