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.

Context: 'I need an extra supply of food, as I exercise a lot! 🙂' 'Hmmm. And the firewood?' 'I get cold easily. I need the firewood to get warm. I might catch a cold.🙂'
Utterance: 'I think water should be your priority. You have food and firewood also in your basics. I will let you have the 3 water but I will need the 3 Firewood and the 3 Food. I have a medical condition.'
Yes

Context: 'I will provide you the food, but I am asking only one for my people.' 'I am giving you all the water, how come you need the food? ' 'The main reason is to prevent us from cold. Please provide three wood and three water. If this is okay, then I will provide you three food.'
Utterance: 'Food doesn't prevent cold. Thank you for giving me all the food but I need 1 wood to cook the additional food. You still end up with more items in the end '
Yes

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.'
No
