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.

Q: Context: 'Hello, lets get things started. How would you like to split items?' 'Hello! Hope your after noon is going well! I have 2 kids so I feel like the water is the most important for them. Need to keep they hydrated, ya know? 🙂'
Utterance: 'I also need water with my medical condition I have to take lots of meds. I can give you extra firewood so you can boil more water easily.'

A: Yes

Q: Context: 'I understand where you're coming from but I'm afraid that is not acceptable. My family's comfort is my top priority and I will be needing at least 2 firewoods to make sure they are kept warm. I would also request some extra water. ' 'I need a minimum of 2 firewood. You can have 2 water. I would now like 2 food.' 'It seems we both have a big need for firewood. 😮 If you insist on 2 firewood, then I insist on getting 2 water AND 2 food along with 1 firewood.'
Utterance: 'I insist on 2 firewood 🙂. I would be happy to let you have 2 water. Are you sure you need 2 food?'

A: Yes

Q: 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. 🙂'

A:
No
