TASK DEFINITION: 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.
PROBLEM: Context: '☹️Oh, that sounds awful. Are you sure you need all three packages of firewood?' 'I might be able to get by with just two... I'm on a diet though, so I don't need as much food.' 'That's a relief. I actually have a friend joining me and they don't have their own food supply. I don't have enough for two people.'
Utterance: 'You can all the food if you need it.🙂'

SOLUTION: No

PROBLEM: Context: 'hi there🙂' 'Hello. How are you today? 🙂' 'Pretty good!  I am looking forward to going on this camping trip with my family.'
Utterance: 'Same here! We had a couple bumps in the road though, as our freezer stopped working so all our food went bad ☹️'

SOLUTION: No

PROBLEM: Context: 'I am looking for food, me and the kiddos need to eat many snacks for energy while exploring hiking trails. What about?' 'Okay, that makes sense. I really need water. I am willing to trade you all 3 of the food if you will give me all of the water. What do you think?' 'I think that sounds okay but I need at least one water please?'
Utterance: 'If you want one water you can only have 2 foods. Do you really need the water? It sounds like food is a much more important item to you🙂'

SOLUTION:
Yes
