instruction:
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 self-need strategy, otherwise output No. self-need is a selfish negotiation strategy. It is used to create a personal need for an item in the negotiation, such as by pointing out that the participant sweats a lot to show preference towards water packages.
question:
Context: 'Hello I would like to have two bottles of water and in trade will take 1 food and firewood for a higher amount of water.' 'Hello. I would consider giving you 2 waters for 3 firewood and 2 food. I have a large family so the additional firewood will help with warmth and cooking food. 🙂' 'That sounds like you could  really use the extra warmth for your family'
Utterance: 'Yes it is very much needed. My family doesn't have a lot of extra bedding so having the warmth of a fire will help make sure we don't get cold at night 🙂'
answer:
Yes


question:
Context: 'Hey there, unfortunately, I'm in a bit of a quandary with firewood too, as I am going to a place where it's fairly cold and will need more for heat. ' 'thats terrible! i broke my leg and wont be able to collect my own firewood , could i maybe get 2 packages? ☹️' 'Terribly sorry to hear that; it sounds like you won't be able to camp much in that condition. I assume you have someone coming along to help you because of your leg?'
Utterance: 'just a bunch of children under 5 who wont be able to gather firewood. so i desperately need at least 2'
answer:
Yes


question:
Context: 'Hello. Wow! That does not sound good. My sister just called and let me know she will be coming tonight. She is bringing food so i have plenty to share. 🙂' 'That's some good news. 🙂 Are you sure she is going to be bringing food with her?' 'Yea She is bring tons of food. So don't worry we have plenty of food to spare. 🙂 She did forget to get water. I didn't know she was coming so i didn't grab any and I forgot the 3 packages of water for myself at the store. ☹️'
Utterance: 'Yikes, that's not good. Water is very important, especially if you now have to take care of two people at your campsite now. I do have 3 packages of water but I don't think I can spare it all.'

No
