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.

Question: Context: 'Doing good. How are you today?' 'I'm good as well, trying to plan my camping trip for the weekend. Do you enjoy camping?' 'I do but it's hotter than I expected. Probably gonna drink a lot of water.'
Utterance: 'It pretty cool where I live so I don't need many water. But I do need a lot of food and firewood. Have a huge family and we do a lot of grilling. '

Answer: Yes


Question: Context: 'Ok.  I am looking to have one package of water and on package of food.' '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.' 'Well, I need 1 package of each.'
Utterance: 'One package of each might be doable--I thought you said you only needed one package of water and food? Can I get 3 packages of firewood at least? That's easily the most important to us, I don't want anyone getting a cold weather injury.'

Answer: Yes


Question: Context: 'I was more thinking 2 Firewood for me , 1 food and 1 water? The rest would be yours.'

How does your group feel about water though?'
Utterance: 'Water is not that important for us but the firewood is a deal breaker for us ☹️'
