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.

[EX Q]: Context: 'Howdy! Looking for firewood, water and food--really trying to get 3 packages of each, want to make sure my family has enough supplies for camping. I don't want anyone injured or our vacation cut short.' 'Ok.  I am looking to have one package of water and on package of food.'
Utterance: 'Is there any way you could let us have 3 packages of each? I'm just trying to make sure my family has enough, we don't get to get out in the woods that often. It's really important to us.'
[EX A]: Yes

[EX Q]: Context: 'Not this time, I really need all the firewood and food is a large need for my family of 8. We need the firewood to cook all our meals from the animals we hunt since we are short on food.' 'But these are only additional packages☹️' 'I get that and understand completely. I have a large number of mouths to feed making the food a necessity or all the firewood to cook whatever we hunt. How many you have?'
Utterance: 'I have three.'
[EX A]: Yes

[EX Q]: Context: 'Same, my kids are as well! They have not been camping before. They are super excited about the campfires. I'm worried I don't have near enough firewood though. I just found out you can't cut any trees down where we are staying. ' 'oh no I'm so sorry to hear that. My kid are looking forward to the ghost stories around the campfire.' 'My kids will enjoy that as well. I'm hoping I can pack several extra things of firewood. If I could get 3 more packages I would feel better about having enough firewood to have campfires during the evening and to cook on. '
Utterance: 'ok I completely understand. I am more than happy to offer you 3 firewood in exchange for 3 food. If you are ok with splitting 2 water for me and 1 for you that works well. My kids need food and water for their medications.'

Yes
