TASK DEFINITION: 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.
PROBLEM: Context: 'Hello' 'Hi can I ask what camping supplies you most need?' 'I would like the 3 food packages because my sister forgot to pack any food items for the trip. You can have all the water and firewood. '
Utterance: 'Oh no!  I have my daughter with me and she really likes to eat.  I was hoping to get at least some of the food.  Do you need water or firewood more?'

SOLUTION: Yes

PROBLEM: Context: 'I am okay. How about I give you one and half then I get some firewood from you?' 'No I need at least 2 waters.  But I am willing to give you all 3 foods, if I get all the firewood.  Does that work for you?' 'Okay I will give you 2 waters. I actually need more of firewood. If I can get 2 I will be glad.'
Utterance: 'Well I really need the firewood because I have small kids with me and it would be hard for me to get some free time to get the firewood, but I would be willing to give you 2 firewood since I get two waters.  What are your thoughts about the food?'

SOLUTION: Yes
