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 uv-part strategy, otherwise output No. uv-part is a selfish negotiation strategy. It is used to undermine the requirements of the opponent. For instance, suggesting that the opponent would not need more firewood since they already have the basic supplies or a suggestion that there might be a store near the campsite where the opponent can get the supplies instead.

Input: Consider Input: Context: ' I appreciate your willingness to discuss this, so we both get a fair deal. I would really like if I get 3 food, 1 water, and 1 firewood. Then you would get 2 water and 2 firewood. You said that you really need water and food, so I think that would work best for both of us to get what we need most. What do you think? 🙂' 'Np, problem, water is high in demand on my end with the amount of kiddos I am taking. Water is my main concern, will you be okay with 3 Foods, 2 Firewoods and no water?' 'I would really like 3 food, 1 water, and 1 firewood if possible. Would you agree to that instead?'
Utterance: 'If you were me would you be happy with 0 Foods, 2 waters, and 2 Firewoods? when water is your priority? maybe we can make it even, your highest priority is Food and mine is water? you can have all firewood? I will be shorten out on everything except the water and youll get 3 foods and 3 firewoods, while i only get 3 waters?'

Output: Yes

I see there are some extra supplies to share.  I could really use the water and firwood.  🙂' 'oh yeah, you definitely do. we have all of our stuff and mostly wanted to hike and have picnics during our camping trip '
Utterance: 'Great. If you mainly doing picnics do you want 3 Food?   I could use the the supplies.  🙂'

Input: Consider Input: Context: 'Well I don't mind either way about the food. I'll recommend giving you 2 firewood 1 food and 1 water. ' 'how about you get 3 waters and 2 foods? Does that work better?' 'yes how much firewood. I need at least 1 to cook the food.'
Utterance: 'you should have enough firewood in the basic supplies to cook the food i think, with three waters and 2 foods you get 5 items and i get 4'


Output: Yes
