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: 'Okay I am willing to take your offer as I think you need the firewood more than me and I could use the extra water for hygiene related issues.' 'Thank you! I am grateful! ' 'You are very welcome!'
Utterance: 'I'm looking forward to this camping trip now knowing that we will have enough firewood to last🙂'

Ex Output:
No


Ex Input:
Context: 'Well, let me think on that.  Why do you need so much water for a starter?' 'I get dehydrated easily. I need to water so that doesn't happen. 🙂' 'Hmm.  And why do you need so much food?'
Utterance: 'I need an extra supply of food, as I exercise a lot! 🙂'

Ex Output:
No


Ex Input:
Context: 'Would they be okay with 2 food?  Otherwise can give you an extra and I can take either an additional water or firewood 🙂' 'I have a great offer.  How about I take 2 food, 2 firewood and 1 water and you will get the extra water your camp needs!!' 'We place a premium on the water.  That's the same amount of water, do you mean we take 3?'
Utterance: 'I do need some extra water.  So I will need to take 1, but our preference is food and we would need firewood to cook it on.  if you're OK with this, I will submit it.  Its a great deal I think and we'll both get what we need'

Ex Output:

Yes
