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.

Example Input: Context: 'I could do one firewood and all the food?' 'And I would get all the water?' 'How about you get two firewoods and two water, and I take the rest?'
Utterance: 'No I think I need all the water. I'm in the desert and there's absolutely no water supply. '
Example Output: Yes

Example Input: Context: 'hi how are you' 'I am well, thank you.  Yourself?'
Utterance: 'good here, I will need 3 water as I need it to survive'
Example Output: Yes

Example Input: Context: 'I am so excited to go camping!  I am planning a nice long walk in the woods to decompress from the hectic days of working.'
Utterance: 'I am too.  I've been thinking of this since COVID.  I hear we have some materials to share between the two of us.  What are you thinking?  For me, I am from the South so I get cold easily 🙂 so firewood is my main priority.'
Example Output:
Yes
