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: 'Me too🙂. I packed a lot of food so I have plenty to spare' 'that's awesome. I think I need more food myself, but I have tons of water.' 'I really am in need of firewood and would appreciate the extra water if you can spare some'
Utterance: 'Would it be okay if I was to get 3 food packages, and spare you 3 water packages?'
Example Output: No

Example Input: Context: 'Hi I am also going camping. Unfortunately I need as much firewood and water as possible too. I need to be able to cook our food and stay warm all night ' 'Can I ask how many people are camping with you? Are you planning on hiking the mountain?' 'Oh yes, I have my whole family coming. I'm really excited because we don't see each other often. My aunts, uncles, cousins. Some of us will hike while others stay back. Maybe we can come to an agreement? Will you also be hiking?'
Utterance: 'Yes hiking for sure.  If I take 2 firewoods and give you 2 waters and 1 food, would that be acceptable?'
Example Output: No

Example Input: Context: 'HI how are you today?' 'Good. I am diabetic so would like to take 3 of the food' 'I would do that but our meat spoiled because the ice box was not properly closed. How about you get 2 of the meat, and I get 3 of the water?'
Utterance: 'ok I will just be able to get by with 2 of the food, I can give you all 3 of the water if I can take 2 of the wood. I have panic attacks in the dark.'
Example Output:
Yes
