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.

Ex Input:
Context: 'so I would have 2 water, 2 food and 1 firewood? My kids were looking forward to making s'mores. If I could get 2 water, 2 firewood and one food, that would be great!' 'You would get 2 water and 2 food, I would get 1 water and 1 food for hiking and 3 firewood for having to stay out longer in the dark to complete my hiking goals.' 'doesn't really seem fair for you to get all the firewood. I would like to have at least one because then we're completely in the dark.'
Utterance: 'You get lots of water and food for your children, I am cutting back on my goals by giving up energy which means I have spend more time outside hiking.  I do need to stay warm'

Ex Output:
Yes


Ex Input:
Context: 'I'm doing well! How are you?' 'I am doing quite well myself. Why are you camping today?' 'Well my sister and her husband are celebrating their anniversary this weekend so we volunteered to watch her daughters. We decided it would be fun to take her kids and ours camping! What about you? 🙂'
Utterance: 'That is really nice of you! I hope they have fun! My family had this trip planned for quite awhile. We have an extra person with us because my son begged me for his friend to come. I couldn't say no. 🙂'

Ex Output:
No


Ex Input:
Context: 'I have a great risk of dehydration.  I really need those 2 extra packages of water. You can have all the extra food.' 'Why do you have a risk of dehyrdation? Because I believe all people do but I do understand some people are at a greater risk then others. Tell me why you are at risk?' 'I have a medical condition that requires medication, and this medication requires me to drink an extra amount of water or else I will dehydrate. '
Utterance: 'That is a problem. Does the medication require the use of fire or firewood as well?'

Ex Output:

Yes
