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: 'How many wood do you think you need?' 'I would like 2 of the firewood. What do you think? ' 'I don't need wood as I am usually warm so I think we can work out a deal. I like to have more water and I usually get thirsty.'
Utterance: 'That sounds good to me. 🙂 I think we can make a good deal.'
Example Output: No

Example Input: Context: 'Yes, at least 1 of firewood, one of water and one of food.' 'Okay, that would work for me. I'm sure you have good reasons.' 'Do you have a small group, like I do?'
Utterance: 'No, I have a pretty large group, unfortunately, so we need some extra supplies as well.'
Example Output: No

Example Input: Context: 'It's nice to know the firewood is not important to your camping trip. I'm glad I can have all the firewood to myself. How do we get to share the other resources. ' '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. '
Utterance: 'Great. So if I have three food and one water, you can have three firewood and two water. Would that work for your trip?'
Example Output:
No
