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: 'Food is also my highest priority, but firewood is also pretty close for me.' 'Would you be willing to take more firewood for less food?' 'Yes I think that sounds fair.'
Utterance: 'So if I take 2 foods and 1 firewood, you take 1 food and 2 firewood. What would be fair for water?'

SOLUTION: No

PROBLEM: Context: 'Hello! Do you have any sort of preference regarding the 3 camping items?'
Utterance: 'Hello there! It's nice to meet you. Truthfully, I need to get some food and some firewood. What do you need?'

SOLUTION: No

PROBLEM: Context: 'Camping yay!' 'Hello! how are you? hoping today is finding you well. I was wondering if I can get all 3 of your Firewood, I am willing to trade for all 3 waters. I am camping with 40 kids, its our annual youth camp. its rainy season too, I really want to ensure I have enough dried wood with us. need lots of firewood for the amount of cooking I will be doing, keep the camp warm, and specially to keep those pesky bugs away. what do you think?' 'I could really use the firewood too, it will be very cold where we are going. Since it will be cold, we will not be drinking much water. How about 2 firewood for you, 3 food for me?, '
Utterance: 'May I ask how many are going camping with you, i would agree, but the needs of children are different than adults. I will need at least 1 food, to ensure I have enough for the kids. '
