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 Q]: Context: 'That is fair. Could I also have 1 food so I do not starve' 'what about your basic food rations?' 'I am severely malnourished and could use just one more food please'
Utterance: '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'
[EX A]: Yes

[EX Q]: Context: 'I too have children who eat like adults they too can't able to withstand hunger so you please show some mercy and give me 3 food packages and take all water and firewood' 'No I need extra food too. I cannot let my children starve and you cant let your children go thirsty. So if you cant agree to share the food i will walk away from the deal.' 'There is no point in walk away. This deal should be done mutually and beneficial for both. So its better I will take 2 food packages, you can take 1 food package, 2 water and 3 fire wood .Hope this will definitely work for you.'
Utterance: 'No i absolutely need 2 food packages and 1 water. How about we do it like this... You take 1 food package, 2 waters and 2 firewoods. Does that work for you?'
[EX A]: Yes

[EX Q]: Context: '1 food for 1 firewood isn't a good trade for me. I would need at least 1 firewood and 1 water to trade for 1 food.' 'Here is my proposal. I will take 2 firewood, 1 food and 1 water.  You can take 2 food, 2 water and 1 firewood.' 'That sounds good to me!'
Utterance: 'ok, so to make sure we're on the same page. You get 2 food, 2 water and 1 firewood. I will take 1 food, 1 water, and 2 firewood?'
[EX A]:
No
