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.

Ex Input:
Context: 'Got you! I really need firewood to make smores and I don't think we have enough to last the whole night!' 'I was hoping to pick up a lot of wood. It has rained around here and the wood is soggy in the forest.' 'Which item do you prefer the most?'
Utterance: 'I know how to filter water so you can have all of the water. I would like as much firewood as possible.'

Ex Output:
Yes


Ex Input:
Context: 'Great! Food is not my priority but water and food is.' 'awesome, you can have 3 water and i'll take 3 food?' '🙂 I am fine with it. How about the firewood?'
Utterance: 'i'll take 2, you can have 1? '

Ex Output:
No


Ex Input:
Context: 'I would be willing to give you all of the firewood (3) and two of the water (2) while I get the rest' 'Ok great, are you going to be ok with getting your own water and firewood during the trip?' 'I think that I will be able to, so I'd like to offer you those extras.🙂'
Utterance: 'Thank you, it would have been difficult for me to get more firewood and I appreciate the additional water. So I get 3 firewood, 2 water and 0 food.'

Ex Output:

No
