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: 'Same! I'm a little worried about some of my supplies though. What about you?' 'Likewise! What are you most in need of?' 'Well, I'm camping up on a snowy mountain and I gave some of my food away to hikers who were passing me and were very tired and hungry, so I'd really like to get some more food. Firewood would be useful too, although I do have a thick coat and a sleeping bag. I plan on melting the snow to get water, so I don't think I'll need that too much. And you?'
Utterance: 'I have the same needs. I have a low metabolism, so I need food and firewood to keep me warm and energized. Water I plan on filtering elsewhere.'

SOLUTION: Yes

PROBLEM: Context: 'Hi - I'm so excited for our camping trip. I'm most excited about getting to eat food that I normally don't when I am home' 'Ooh what kind of food?! Like MRE? I'm going to need lots of water because I'm going to the High Desert.' 'Hello! camper, how are you? I need us to make a deal where we all benefit.'
Utterance: 'Yes, I expect that! You need food most and I need water, so let's propose an exact trade? 3 for 3?'

SOLUTION: No

PROBLEM: Context:
Utterance: 'Hello, how are you? 🙂, we are excited to go camping for 2 weeks.

'

SOLUTION:
Yes
