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: 'Same here haha. Is water your lowest priority item too?' 'Yes. We think we have enough water for now.' 'Same here! I am in need of food more than firewood however as I am very hungry. '
Utterance: 'Me too. We have a bigger family and we will run out of food if we don't get some more.'

Ex Output:
Yes

Utterance: 'I think I would be able to make that work. What are you looking forward to while camping? '
