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: 'Hello, how are you doing?' 'I’m doing fine. How about you?'
Utterance: 'I'm doing well. I was hoping I could have the extra firewood because my group decided to camp for a few extra days and want to make sure we have enough'
[EX A]: Yes

[EX Q]: Context: 'No that does work well for me.  If I only have 1 food I need 2 waters and the firewood to make up for the loss of food.' 'What about I have all the food, and you can have everything else? I would think that seems pretty fair.' 'Sorry, I understand where you are coming from but I really need at least one food.  '
Utterance: 'I'm sorry. I would really appreciate having all the foods, because this camping trip is a get togther with my 5 friends one of whom is her birthday and recently lost her mom. So we need lots of snacks to help her celebrate her birthday and support her during this hard time.'
[EX A]: Yes

[EX Q]: Context: 'That is a promising bargain but I want at least 2 firewood, it makes for a fun time for my group.' 'Interesting , because my group feels the same way though. How does your group feel about water though?' 'Water is not that important for us but the firewood is a deal breaker for us ☹️'
Utterance: 'I see.... Well we really would like the firewood too though. Could you reconsider it makes a big difference for us.'
[EX A]:
Yes
