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 am going camping too.  May I ask where you are going canoe camping?' 'We are going to camp in Oregon.  We are looking forward to it.  The views and scenery should be gorgeous.  How about you?' 'I am going to the Allegheny mountains in Pennsylvania.  I'm going to be hiking a lot so I will need some extra food.  Let's balance out the food and water somehow....'
Utterance: 'Sounds good.  We will also be hiking a bunch and I have little kids who go through water and food like crazy.'

Ex Output:
No
