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: 'Yes. And then I'll get 2 food and you'll get 1 food. And then I'll get 2 firewood and you'll get 1 firewood. How's that?' 'That sounds good to me.  It looks like it will be a good weekend for both of us.' 'I think so too! I hope that hurricane doesn't cause any issues to our plans!'
Utterance: 'I think we will be ok.  I'm more worried about the heat.  You can submit the deal if you want.'

A: No

Q: Context: 'Hmm.. well let's see! What is your second priority? I would be willing to give up all of that, if I could get at least 2 firewood. You're right, it sure does get chilly ☹️' 'What if I got 3 foods and 2 waters. and you got 3 firewood and 1 water. If I could get a little more food that doesn't need to be cooked over the fire I might be able to get by. And I'll need to buy more water so I don't have to boil it since I won't have much firewood. ' 'I would say that sounds like a good deal! I am a little worried about water though, there aren't any sources of water where we are going. Hmm..'
Utterance: 'I think having 3 packages of firewood will help! you can always boil water from a  fresh spring 🙂'

A: Yes

Q: Context: 'I am doing well, how about you? It is another hot July day.' 'I am doing pretty good. I am going camping this weekend and just double checking to see what extra supplies I need' 'I love camping, have not gone in a while. Have you ever camped by a lake?'
Utterance: 'Yeah! I usually camp by the lake so I can use the lake water when I need extra water.'

A:
No
