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.

Input: Consider Input: Context: 'I'm doing pretty well, just preparing for this camping trip.' 'ME as well! we are a group of big eaters, and are looking to take lots of food.' 'That is fair as there is no showers or sinks at my campsite so I am looking to take water :) '
Utterance: 'We will likely also need to take water too. Need to be able to wash up.'

Output: Yes


Input: Consider Input: Context: 'I do need some myself as well' 'I suppose it is important - we'll definitely have split that up somehow. ' 'Well how about this. I take all the Food, and 1 Water. You get all the Firewood and 2 Water.'
Utterance: 'we're definitely thinking alike - That extra water would go a long way to keep us safe and comfortable'
