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: 'Hello there! It's nice to meet you. Truthfully, I need to get some food and some firewood. What do you need?' 'The main thing I like to do when camping is a lot of hiking (pretty much all day), so I was hoping to get as much food as possible so I can remain active.' 'I'm sure we can come up with a compromise! I understand the need for extra food with exercise. Sometimes I get low blood sugar and need an extra snack. I'll give you 2 food if I can get 1.'
Utterance: 'I think that is a totally fair split for the food. And I actually don't need a lot of firewood. I would be willing to give you all of it in exchange for the water.'

Output: No


Input: Consider Input: Context: 'I would like 2' 'I will  be happy to let you have 3 packs of food , but I need 2 packs of firewood' 'I am also letting you have all 3 packs of water. I think we need to consider how to split the firewood in a fair manner.'
Utterance: 'What do you think is  a fair deal with the firewood'

Output: No


Input: Consider Input: Context: 'I would consider giving you all food and water if I could get all of the wood.' 'Oh really? I think I am able to do it without firewood then. The kids will be full and probably won't ask for smores' 'Or 1 wood for you and 2 of food and water?'
Utterance: 'I am fine with that as well. So I get  wood, 2 water and 2 food?'


Output: No
