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: 'do you have a particular item preference?' 'I do.  I have been looking everything over and feel this won't be to hard to come to an agreement' 'Well my camp places a premium on water.  How would you feel about for me: 2 water, 1 food, 1 firewood?'
Utterance: 'I think we're on the right track.  I am bring my 2 kids with me and they eat everything in sight.'

Ex Output:
Yes


Ex Input:
Context: 'The main thing I like to do when camping is a lot of hiking (pretty much all day), so I was hoping to get as much food as possible so I can remain active.' 'I'm sure we can come up with a compromise! I understand the need for extra food with exercise. Sometimes I get low blood sugar and need an extra snack. I'll give you 2 food if I can get 1.' 'I think that is a totally fair split for the food. And I actually don't need a lot of firewood. I would be willing to give you all of it in exchange for the water.'
Utterance: 'I think so, too. I'm glad you offered that - we got stuck in the rain and need the firewood to dry our clothes. I'd be more than happy to give you all the water for all the firewood.'

Ex Output:
Yes


Ex Input:
Context: 'No that doesn't work for me. I also have children with me. 4 children in total.  how about i take 2 food packages and 2 water packages and you take 1 food 1 water and 3 firewood packages.' 'I too have the same issue. I am also asking for children only , better you could accept 1 food , 2 water and 3 firewood, I hope this deal will work out for you' 'I need at least 2 food packages and at least 1 water. I can live with out any extra firewood.'
Utterance: 'Please do understand my situation its very very critical to give 2 food packages to you.Instead you can take 3 waters and firewood too.'

Ex Output:

Yes
