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: 'Okay so would 2 firewood for you and 1 for me work, and 2 food for me and 1 for you?' 'I can definitely agree to that.  What was your second preference?  Water was my third.' 'firewood is my second preference and water is my third'
Utterance: 'Well, water doesn't benefit either of us much, so you can have two. So you will take 2 food, 1 firewood and 2 water?'

Output: Yes


Input: Consider Input: Context: 'The weather is going to be really hot. Could I have 2 water in exchange for you receiving 2 food and 2 firewood?'
Utterance: 'I have a low immune system and need to stay warm how about I get all 3 firewood in exchange for the 2 water. '

Output: No


Input: Consider Input: Context: 'I am good, thank you.  What are your preferences? I really need the extra food packages.  We are doing a lot of hiking and mountain biking and there are no grocery stores for at least 50 miles.🙂' 'Oh wow that is quite a lot of hiking! I think we will be hanging out a lot overnight and so I am looking for more firewood if possible. My kids can't hike very far and want to do more with smores and marshmellows. ' 'I can work with that.  I am willing to give you all of the firewood.  We are in a hot climate and won't need too much.  Being in a hot climate and with a lot of exercise, I am hoping to take the three water packages. '
Utterance: 'Thank you for that. I'm happy to give you the food packages as well as we shouldn't need extras. Being around the fire, we are going to be hot as well and dehydrated. I say let's try and split the waters. '


Output: No
