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.

Context: 'Okay, I need firewood to stay warm and cook food. I'm willing to give up some water for more firewood.' 'Unfortunately i need the firewood. My body has trouble maintaining heat. I need as much as i can get ☹️' 'Okay, well if you need water and firewood, that only leaves food. If you can part with extra food, here's what I'm proposing'
Utterance: 'Yes you can definitely have all the food. Maybe 2 firewoods and 2 waters for me?'
No

Context: 'Well, we do need the water pretty badly. But I guess wanting all the water is stingy so I will pack extra water since we are not packing food. How about you guys receive 1 water and 3 food units?' 'If you feel you absolutely need the 3 waters, I will let you have them provided I can have 2 firewoods along with the 3 foods.' 'That is so nice of you. Being that you have family, you might need more firewood for cooking for the crew! Do you agree? And how many kids are you traveling with? '
Utterance: 'I have 2 kids and want to make sure they stay warm.  The firewood will go a long way in keeping them comfortable.'
Yes

Context: 'Well i am also going on a trip, in a very cold climate, unfortunately i have a medical condition where i need to stay hydrated and warm or i can have siezures' 'i understand friend. i need 2 pack of water and 3 pack of food and 2 pack of fire wood. can you please help me ' 'No way can you have everything, I will need 3 packs of firewood 2 backs of water then you can have all the food'
Utterance: 'i have sicked people and kids so i must need food water fire wood. please help me friend'
