TASK DEFINITION: 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.
PROBLEM: Context: 'Hi fellow camper! What are your needs for the extra provisions.' 'Hi i'm really excited for camping. I am looking for food and water ' 'Yes, a much needed getaway. Oh my, we need the same provisions! How would you be with receiving two waters, one food package, and two of the firewood?'
Utterance: 'I think I would be able to make that work. What are you looking forward to while camping? '

SOLUTION: No

PROBLEM: Context: 'Hi there! How are you?' 'Hello good morning I'm well thank you.' 'Let's talk about what we need. First, I don't eat meat, so I really feel like I'd need a little extra food, as I couldn't hunt or forage for food at all. I feel like I could survive without a ton of water, but would need water, as I hike a lot and cant trust any sources'
Utterance: 'I've also planned my trip to include a lot of hiking and so I have a high priority for extra water, as like you've said you need to stay hydrated on your hike and you can't trust any source. How can we divide up the water as that seems to be the number one priority for us both.'

SOLUTION: Yes

PROBLEM: Context: 'I don't have much food, but you can take one package and I can take two? ' 'thanks  that would be great!  I also need an extra package of firewood, I will probably need it cooking.  Do you have a spare package of it as well?' 'I don't need much firework, so you could have two packages. Could I take all of the water so I can wash my clothes? '
Utterance: 'Sure, I can wash whatever that needs to be washed out in the lake or river.  🙂'

SOLUTION:
No
