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 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.
PROBLEM: Context: 'Hello, are there any of the three items that you want to be sure you have enough of? 🙂' 'I want to be sure that I have enough firewood.  I want to relax, sit around the campfire, and roast hot dogs and marshmallows.  What about you?' 'That sounds great! I like all three items, but I definitely want to make sure I have enough water, especially to drink and stay hydrated and full of as much energy as possible. I require a lot of liquid as a 6-foot-4, 260-pound guy!'
Utterance: 'I don't think the weather is going to be that hot, and I don't plan on doing any hiking.  So, I should need much extra water.'

SOLUTION: Yes

PROBLEM: Context: 'Firewood, due to the area that we are going to. How about you? ' 'Oh I see. You can have all 3 firewood if you are ok with me taking all 3 food.' 'Hmm, well I'd love to get some of the food. What I took 2 firewood, 1 food and 1 water? '
Utterance: 'Sorry but I really need all 3 food. All the food I brought with me has spoiled because the AC in my car broke. ☹️'

SOLUTION: Yes

PROBLEM: Context: 'Kindly understand our need as we are struggling with hunger now.'
Utterance: 'At the same from my side. We need foods because my child is hunger'
