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'm doing well. I'm looking forward to going on my camping trip but will need some additional items to make sure the trip is safe, healthy, and enjoyable. ' 'Same here. ' 'I have diabetes, so it is very important to me that I get extra packages of water and food. When I'm at home, I always need to pack extra drinks and snacks for myself in case I go into shock and need to take medication. The trip could be very dangerous for me if I don't have access to these additional supplies. '
Utterance: 'Actually mine own purposeful need is firewood and water. Being on a first time adventure, I lack these items as I was inadequately prepared.'

Ex Output:
Yes


Ex Input:
Context: 'It's been so cold these last few days, I'm worried that I didn't bring enough wood for the next few nights.' 'That is unfortunate. How about I give you are my firewood for all your food?'
Utterance: 'That is a very generous offer but I think I need to keep some food to be safe. Do you need any water?'

Ex Output:
No


Ex Input:
Context: 'Hi, I would like to get 2 additional packages of food, 2 additional jugs of water, and 1 additional bundle of firewood. I need the additional food because I will have 3 children with me on the trip and one of those being a baby. The baby needs water for her bottles and I need an additional bundle of firewood to warm her bottles.' 'Hi, I appreciate your response. I would like to compromise. I will give you the bundle of firewood you requested as well as the 2 packages of food. However, I would like to get 2 jugs of water. I have 2 other adults with me on this trip and they require more water to stay hydrated than a baby would.'
Utterance: 'That actually sounds pretty good to me. 🙂'

Ex Output:

No
