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: 'Hi, I would like to get 3 firewood, 2 waters and 1 food pack.' 'Hello, I am in need of more water than just one,could you possibly allow me to have two and the other items are fine'
Utterance: 'I have a bunch of kids and need extra water. I can give you 2 food packs instead.'

SOLUTION: Yes

PROBLEM: Context: 'Hmmm...I'm pretty muddy due to clumsiness, so I may need one extra. I could give you two waters and all of the firewood. What do you think? 🙂' 'So are you suggesting that I would get 2 waters, 3 firewood, and no food?' 'Right! Well, beyond the food you already have. '
Utterance: 'I have an extra person camping with us that I didn't expect when I bought food, so I could use one if you're willing 🙂'

SOLUTION: Yes

PROBLEM: Context: 'i will need 3 firewood packets.  I have a terrible disease that prevents my circulation from working properly.' 'That does sound bad. I am going camping and my kids might want to stay up late so I will need extra firewood for this to keep light and more warmth. I will take all 3 extra of the food and the water but I need 2 firewood also.' 'no that won't work.  I will give you 3 food and 1 water.  I will take 3 wood and 2 waters.'
Utterance: 'I did not know you wanted water. Ok, that's great so I will take all 3 extra packages of food.As for the water I would like 2 waters because my dog is coming along with us for our trip and extra water for him will be needed.'
