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 Input:
Context: 'Hmm.  And why do you need so much food?' 'I need an extra supply of food, as I exercise a lot! 🙂' 'Hmmm.  And the firewood?'
Utterance: 'I get cold easily. I need the firewood to get warm. I might catch a cold.🙂'

Ex Output:
No


Ex Input:
Context: 'Hey there - looks like we are both going camping!  I'm from the South so firewood and water are a high priority for me.'
Utterance: 'Wow, thats awesome! Yes, I am! Well, that's great because water isn't super important for me. Firewood is though. '

Ex Output:
No


Ex Input:
Context: 'Hi there! How are you?' 'Great! I'm very excited to go camping, how about you?' 'I am! Now, I need a lot of firewood because we were planning on burning some earlier (to start cooking meals and such). I also need some extra food in case bugs come and eat some (like last trip, ugh). How about I take 2 firewood, 2 food, and you take 3 water, 1 firewood, and 1 food?'
Utterance: 'Would you be open to taking 1 less firewood, I would give you 1 food for it. The weather is supposed to be extra chilly and we did not bring warm enough sleeping bags so we need the extra firewood to avoid freezing to death!'

Ex Output:

Yes
