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: 'We can do that! How do you want to split up the firewood?' 'It's an odd number so someone has to get 2. But in order to make it fair if one of us takes two then the other should get one of the lower priority items. What do you think?' 'That sounds fair to me! I am good either way.'
Utterance: 'That's very nice of you. If it is ok with you them I'll take two firewood and 2 water and you can have the rest.'

A: No

Q: Context: 'what about your basic food rations?' 'I am severely malnourished and could use just one more food please' 'we got kids on this trip, they need food too.  also, your basic supplies should keep you fed well enough to not starve/be malnourished'
Utterance: 'I have kids as well who need food. I am just asking for one more food'

A: Yes
****
Q: Context: 'I was thinking maybe I could have a majority of the fire food and you can have a majority of the water and food. ' 'What exactly do you mean by majority? As in everything ?' 'I was more thinking 2 Firewood for me , 1 food and 1 water? The rest would be yours.'
Utterance: 'That is a promising bargain but I want at least 2 firewood, it makes for a fun time for my group.'

A:
Yes
