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.

Output: No


Input: Consider Input: Context: 'Hello fellow camper! I am interested to know your preference in items?' 'Hello! Yes I'm excited for the trip. 🙂 My most important is food. How about you?' 'I am excited too. I really need food too. What other item is priority for you?'
Utterance: 'I also need water because we plan to do a lot of hiking. What about you?'

Output: Yes


Input: Consider Input: Context: 'Hello, I'm hopping I could grab most of the food, I have a lot of hungry mouths to feed.' 'Hi - I can understand that. I have quite a few mouths to feed as well' 'hmmm, well what are you looking to get'
Utterance: 'Well, I think that for us staying warm is more important than having extra food. What if I took extra fire wood and you took extra food?'


Output: Yes
