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.

Q: Context: 'Hey, I think that this is nice, we get to go camping and get extra stuff. But definitely need more food and firewood' 'Yeah, I think I'm okay with firewood, but I'd really like more food and water.' 'That fine then. If you want you can have most of the water and I can have most of the firewood. Sounds good?'
Utterance: 'That seems fine. How do you want to split the food? I grew up poor so I'm always afraid of starving 😮'

A: Yes

Q: Context: 'I will also need some Firewood too to start a fire' 'I feel for firewood we dont need as much, as we are going to be camping, with that means, in my opinion, with branches and brush available, maybe we can take 2 fire woods, what do you think?' 'Since I got some food already, can I get 3 water, 2 firewood and 0 food then?'
Utterance: 'can we do at least one food? if thats okay with you? I would like to have extra food in case something happens, i will be able to have the extra supplies. '

A:
Yes
