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: '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 Output:
Yes


Ex Input:
Context: 'Is there a reason you want the 2:1 split? Food my group's largest priority by a large margin (We eat a lot). It's worth a lot more to my group then the firewood would be.' 'That's why I would like to give you 2 and I will take 1 food.  I have 8 and 10 year old boys.🙂' 'I'm interested in hearing more about why you want a 2/1 split: Is the food worth more to you than the third firewood? If so, I'm happy to do that split, but I'd like 3 water in return.'
Utterance: 'Okay, like I said I have two growing boys with a very healthy appetite.  They will make my life miserable if they don't have enough to eat.  I would be willing to give you the 3 water.'

Ex Output:
Yes


Ex Input:
Context: 'Sounds good.  We will also be hiking a bunch and I have little kids who go through water and food like crazy.' 'What if I get 2 food packages and 1 water package....and you would get 1 food package and 2 waters?' 'I think we will need more extra food than that.  How about the reverse, I get 2 food and 1 water and you get 1 food and 2 water.'
Utterance: 'I could do that if I could then get 2 packages of wood as well because it's been bitterly cold this time of year at night in the Alleghenies.'

Ex Output:

Yes
