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'm in a strong need for food and water. Please let me have a few packages of food and water. I'd gladly trade all my firewood for it.' '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. 🙂'
Utterance: 'That's some good news. 🙂 Are you sure she is going to be bringing food with her?'

Answer: No


Question: Context: 'I have not really camped before so I am looking for as many supplies as possible.  What about I get 3 food, 3 firewood, and 1 water. ' 'funnny you but no. so what else will i be left with if i give you those. okay let say i get 2 food, 2 firewood and 1 water.' 'I am really bad at cooking so will probably need an extra good just because I'll ruin one of the 3.  Plus Im bringing 2 dogs they can eat the bad food I make 😮  I dont plan on hiking much so how bought I keep all 3 foods, and you keep all 3 waters and we can split the firewood.  2 for me, 1 for you.
