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: 'Hmm. Maybe we could go out together on a run. 🙂Always nice to have a running partner. So maybe on the water you get 2, me 1. Then on the Firewood the opposite?' 'That would be fun! I feel like I always do better when I have someone to run against.  Competition does me good. That sounds fantastic on the fire wood and water split.  What is your food situation looking like??' 'How about this? 2 for you and 1 for me. Going low carb and mostly brought my own. What do you think? '
Utterance: 'That sounds great! I don't think my chances for catching any fish are pretty slim!'
Example Output: No

Example Input: Context: 'Great, how are you?' 'Pretty good, planning my camping trip, checking on supplies.' 'Here too, looks like the weather has changed for us. We won't have enough water to last as we forgot it. Food, we have some snacks, but not enough to get by for our trip. I'm not overly concerned about firewood since it's so hot. But I'm really concerned about water.'
Utterance: 'Yeah, I'm going to the desert so I'm hoping to have enough water. I'm good on food and I hunt for a lot of it anyways.'
Example Output: Yes

Example Input: Context: 'Awesome. I couldn't agree more. I feel that camping and hiking are both such spiritual experiences. It's such a perfect time to connect with our lord and savior. I love serving others as well.🙂' ':) Yes and you know what we are experiencing some difficulty as some people who said initially they were not going to be able to come and at the last minute are saying that they are coming so we are short on the most important items which are food and was wondering if we could speak about sharing items but due to the people who joined late if I can get food and water you can have more wood as none of us know how to really go into the wild and we do not want to turn away our last minute guests, it would be of tremendous help   ' 'I'm more than willing to help you to the best of my ability. I understand and appreciate the difficult situation you find yourself in. How many packages of food and water do you think you will need for your additional guests? How much wood do you need since you are saying you don't need much?'
Utterance: 'Thanks for your understanding well I think if possible then to meet the situation then how bout 3 food and 2 water then you get all the wood ? That way you can have awesome campfires lasting through the night, we will be going to sleep extra early to wake up very early so we do not need all that wood, as much as we need food to replenish our energy and be ready for another day of long walks to see as much as we can from nature 🙂'
Example Output:
Yes
