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.

Ex Input:
Context: 'I could manage with one firewood and two foods, but if you have canteens for everyone, may I then have all three waters? I had planned to collect water from the river, but I'm worried I may get sick.' 'you pointed out that we will need more!  😮 i will take 2 waters' 'I didn't know you had supplied everyone with water before the trip. I was merely trying to look out for your needs, but you said you didn't need them!'
Utterance: 'I am giving you a lot of food. You are being unreasonable and backtracking. You are getting some of everything with my offers, and there are only two of you.'

Ex Output:
Yes

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. 🙂'
