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.

Input: Consider Input: Context: 'hello' 'Hi'
Utterance: 'Are you really exciting about camping trip?'

Input: Consider Input: Context: 'Nice. Same, it's over 100 degrees where I live. 🙂' 'Yikes! It's a bit colder up here, that's why I would like to bring some extra firewood to stay warm at night.' 'Oh, I see what you did there. No problem I have plenty of firewood for you buddy. 🙂'
Utterance: 'Great! What extra supplies would you like to bring?'

Output: No


Input: Consider Input: Context: 'Actually, I've just thought about it and I'd also like one package of water. I think it'd be fair being that you're getting 2 packages of food.' 'Which means? Did you mean that I would take 2 packages of food and 2 packages of water? Then I will ask for one package of fire wood.' 'Being that you're getting 2 of 3 of the item (food) that for me is the highest value, I think it's only fair that I get all 3 of the medium value items (firewood) and one of the low value item (water). That would give me 5 packages and you 4 packages, but 2 of 4 of your packages are the high value items.'
Utterance: 'Okay then. I agree with you.. Shall we finalize our deal. I will take the 2 packages of food and 2 packages of water.r.🙂'


Output: No
