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: '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: 'Hi friend! I'm very excited to go to the trip' 'Great! Have you checked to see what the weather has been like in the area you are going to??' 'Definitely I will checked. I m eager to prepare each & every things for the trip'
Utterance: 'I have checked and see that it is in the rainy season! I know I need to pack some extra firewood if you can spare me some??'
Example Output: Yes

Example Input: Context: 'I have a big party with varying degrees of health and I'm going to need every bit of firewood and food I can get my hands on!  🙂' 'hi, we may be in luck then, i really would like water as i enjoy walking and hiking, i will require some firewood though so i can roast some s'mores' 'How many people are in your camping party?'
Utterance: 'i have 6, and 2 more could be joining us to make 8 '
Example Output:
No
