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 vouch-fair strategy, otherwise output No. vouch-fair is a selfish negotiation strategy. It is used to call out fairness for personal benefit, either when acknowledging a fair deal or when the opponent offers a deal that benefits them. This can be through an explicit call out or can be implied.
PROBLEM: Context: 'I'm good! I'm looking forward to my camping trip this weekend. How about you?' 'I'm good as well, I hope the weather works with me 🙂' 'Sending good luck your way! Any items in particular you need for your trip?'
Utterance: 'Well, I'll start with a trial offer and we'll go from there'

SOLUTION: No

PROBLEM: Context: 'I totally understand! I am in need of food too, but it sounds like you really need it so I am hapy to give you all of the food if I can have all of the firewood?' 'What is your need for water? I could use some of that, too.' 'I am pretty desperate for water! I tend to get thrisy when camping. Can I have 2 of the water?'
Utterance: 'I could live with that but I'd need to get one firewood. I don't feel comfortable going with so little water but then also not having any firewood, since that's potentially useful for both food and water.'

SOLUTION: Yes

PROBLEM: Context: 'Let's see what we are both thinking and negotiate from there. What are your first thoughts on the additional camping packages?' 'I need all the food packing and some basic needs for the camping, may I know about your first though on which you need additional package?' 'I will need food packaging as well, so unfortunately I cannot agree on you taking it all. I will need 2 of the food packages, 1 of the firewood, and 2 of the water as I want to ensure to feed/hydrate my family of 5.. Does this work for you?'
Utterance: 'I can't agree to this, as I have to feed my family with 7, so I would be needing 3 food packages and 2 water and 2 firewood. will this be agreed by you?'

SOLUTION:
No
