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.

Utterance: 'You can have 2 firewood OR 2 food.  I prefer you take firewood as I need at least 2 food. Each of us gets 2 of something. '

[EX Q]: Context: 'That is so nice of you. Being that you have family, you might need more firewood for cooking for the crew! Do you agree? And how many kids are you traveling with? ' 'I have 2 kids and want to make sure they stay warm.  The firewood will go a long way in keeping them comfortable.' 'I am leaving my little ones home. I feel a little guilty but am going forward with the plan! So, I input our order that you guys receive 3 food, 2 firewood, and no water. Are we in agreement?'

[EX Q]: Context: 'We have 7 people in our family,.. the youngest two kids have hardly been anywhere because of working. I think our camping area has those old fashioned hand pumps.☹️' 'Your two youngest kids are working? How old is everyone? If there's a lot of people, it will be easier to split up the duties and get things done. My son's 3 years old so as much as he's eager to help, there's not much he can do lol.' 'Ha Ha...no my too youngest have hardly been anywhere because of us adults working,  I have teens (17, 15), tweens (13) and littles (10, 7). We 3 boys and 3 girls. We have a 21 year old but he's in a band so h can't go. They all pitch in anytime. They eat a lot so they have to cook from scratch at home. Awww 3 is so adorable...that's when they are sure they can do and will work so hard! '
Utterance: 'Home cooking's the best, yumyums! We're planning on doing a lot of fishing since my son's been in love with fishing toys and is currently in love with eating fish (he hasn't gotten tired of eating it every night for dinner). We're thinking of cooking what we catch every night. Do you have any activities planned for your camping trip?'
