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.

Question: Context: 'Yes i can understand.' 'We will be in an area where there is not much firewood to collect. You have to bring it in.  We hope to cook with it and keep warm in the evenings.

Question: Context: 'All my girls have brought canteens. I must have enough firewood if they will earn their badge. You can have one, but I won't be able to make due without 2.' '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'
Utterance: '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!'

Answer: Yes


Question: Context: 'I totally understand that. And it's pretty important, lol ' 'It sure is..So how much food do you need for the trip? Do you need firewood to cook the food? Thank you for understanding my issues. 🙂' 'I definitely need the food the most. I'm definitely not a "hunter", so if I were to run out, I'd be in pretty sad shape. I do need the firewood for both cooking, and keeping warm. It gets cold at night where we're going. How about youself?'
Utterance: 'Well since we were already given a few supplies before this deal, I was wondering if you could give me all 3 water, and I could give you all the firewood and 2 of the food packages. I only say all the water because we already have some and my medical condition sucks. lol I wish we could camp together! we seem to be a good match. lol! 🙂'

Yes
