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: 'I should be fine, thank you. 🙂 It will be a little bit of work hauling all of my gear and supplies but after I set up camp, it will be smooth sailing. ' 'I'm thinking that we will be able to work out that deal.  I do have the water and that's my main thing I needed.' 'That's great, I'm glad we came to an agreement. '
Utterance: 'Everything looks good.  I'm glad we both got what we wanted.'

Ex Output:
No
