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 other-need strategy, otherwise output No. other-need is a selfish negotiation strategy. It is used when the participants discuss a need for someone else rather than themselves. For instance, describing the need for firewood to keep the kids warm.

Example Input: Context: 'I have been camping before, but it has been a while. You?' 'Same for me!!' 'What sort of extra supplies are you looking for?'
Utterance: 'I would really appreciate if I am able to take 2 of the food packages since I am a vegan and its hard to find options in the woods and if i can have 2 or 3 of the waters because i have a baby coming with me and i need it for his formula! '
Example Output: Yes

Example Input: Context: 'HI, I will have all of the packages of food and 2 waters and 2 firewood and you can have the rest. Unless none is needed for you then I will take them all.' 'i will need 3 firewood packets.  I have a terrible disease that prevents my circulation from working properly.'
Utterance: 'That does sound bad. I am going camping and my kids might want to stay up late so I will need extra firewood for this to keep light and more warmth. I will take all 3 extra of the food and the water but I need 2 firewood also.'
Example Output: Yes

Example Input: Context: 'I love the outdoors, and I am excited to spend time with everyone from camp. It's been since last year when I saw everyone!' 'That's awesome! I really love being out here with my son. Do you think you could spare some Food and Firewood? I have plenty of water if you need some.' 'I am actually planning to make a big dinner for the whole camp tonight. I will feed everyone if you can let me have the water and firewood. You can take the food to eat before dinner.'
Utterance: 'O cool🙂. I can give you all the water and we can split the fire wood. I need a least one firewood to make a fire for my son'
Example Output:
Yes
