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: 'Hello!  I've been super thirsty and as a result I was wondering if I could get all 3 packages of water?'
Utterance: 'I like to hike and will need additional water. Can I take one package and you can have the other two? '

Ex Output:
Yes


Ex Input:

Utterance: 'yeah I didn't pack enough for my trip, so I'm a little worried about my supplies.'

Ex Output:
