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: 'Hi there. I'm hoping we can make a deal about me getting firewood. I get really cold at night and I'd love to have my fire still going in the morning for coffee - I'd gladly share some if you pop by my campsite.' 'I am in dire need of firewood myself. I was planning on bringing food that needed to be cooked over flame. 😮' 'Well maybe we can find a way to split it! This isn't a problem we can't solve. Are you in need of food too, then?'
Utterance: 'That would be great! I don't need food as much as I am in need of firewood, to be honest.'
Example Output: No

Example Input: Context: 'Wood is my highest priority. I need it to stay warm. I'm very cold-natured. What is your highest priority? 🙂' 'Oh that's good. Wood is not my highest priority since I get hot easily lol. My highest priority is probably food because I have a very high metabolism and get very hungry' 'I understand that. I also need food though, because I need the sustenance to help warm me up. So maybe 3 firewood 1 food and 2 waters for me?'
Utterance: 'I still don't think that is too fair though, since you would be getting 6/9 of the extra items and I would only be getting 3... I'm not an avid camper so I need extra amenities to make sure I survive haha. I am flexible on the water though - maybe we can compromise there. I am fine with you having all of the wood. Maybe we could give you 3 firewood, 1 food, and 1 water?'
Example Output: Yes

Example Input: Context: 'Actually, I think I may need more food than water. How about I take the food and we can split the water. You may have 2 waters, if you need them.' 'Sure then. You can take all the food. It's not really a priority to me. ' 'Great. So if I have three food and one water, you can have three firewood and two water. Would that work for your trip?'
Utterance: 'That's perfect for my camping trip. '
Example Output:
No
