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.

[Q]: Context: 'What are your preferences?  I always love having a big fire at night when I am camping and I do think water is more important than food.' 'I like to have a lot of food to keep my energy up, but I might need some firewood to cook that food. I can't wait for my camping trip.🙂' 'I love camping also!  Yes, I can see how you would need firewood if you want to cook your food.  So, food is more important to you than water?'
Utterance: 'Yes, I will need a little water to wash that food down with though. Are you going to be needing a lot of water?'
[A]: No


[Q]: Context: 'Food is also my highest priority, but firewood is also pretty close for me.' 'Would you be willing to take more firewood for less food?' 'Yes I think that sounds fair.'
Utterance: 'So if I take 2 foods and 1 firewood, you take 1 food and 2 firewood. What would be fair for water?'
[A]: No


[Q]: Context: 'hello, how do you suggest we share the items?' 'Hi there! Well first I was wondering what item you think you'd like or need the most?'
Utterance: 'I like firewood and water most'
[A]:
No
