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: 'i suggest we put excess in charge of working on proposition because prevention of excess is not a good first step.' 'I don't know what you mean by "prevention of excess." Can you clarify?' 'what i mean by prevention of excess is that we should focus on getting excess and not to limit it regardless of what we already have because if we should offer some creative approaches by excess. we can both come to an agreement if you are interested.'
Utterance: 'Okay. Lets just try to do some negotiation. I am the most interested in getting more WATER. The water I already have at the campsite looks dirty so, if it is okay with you, I would like all THREE of them. My food has also been stolen by bears and I don't make much left, so I would like TWO of the food items. You can have all the firewood and the other food item. How does that sound? 🙂'

Answer: Yes


Question: Context: 'Can you explain yourself better? What you need the least is food?' 'i mean i will be needing 3 water 2 firewood and 1 food' 'I can't give you that since it wouldn't be fair to me, I'll give you a better offer. I get 3 food 1 water 0 firewood and you get 0 Food 2 water and 3 firewood and 2 fire'
Utterance: 'no am not accepting that 2 water 2 firewood and 1 food'

Question: Context: 'Great, we can split the food, how are you on water?' 'That would be great. I need to have frequent small meals throughout the day so the extra food would help. I have plenty of water. ' 'alright, so I'll keep the water, and firewood, and give you 2 extra food.  Does that sound like a good deal?'
Utterance: 'I actually need one firewood and one food package. I can give you one water. '

Answer:
Yes
