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: 'ok, fair enough.  How about I take 2 firewood as 1 should do you for a couple nights. I also have small children with me and would like to have the fire burning at all times to keep the bugs away. ' 'I really dont see giving up that much of the wood as I cannot risk running out myself. We are camping way too far out to get access to additonal lighting. I tell you what if you will let me have 2 of the fire wood I would be willing to give you two of the food items. I know that racoon probably took your food as well!!' 'Okay that is a deal. I would like 3 water as well because my campsite water is very dirty. I would like to have bottled water to take my medicine with and we forgot to pack it.'
Utterance: 'I may consider 2 waters as we are going to be hiking up the tallest mountain in North Carolina and they say temps may reach 100, I must have some have at minimum of 1 package of water.'

SOLUTION: Yes

PROBLEM: Context: 'Hello! I am very excited!🙂 How about you?' 'Yes!  Would you mind sharing your highest priority item with me?  My most valued item right now is Food actually' 'I am willing to share everything.'
Utterance: 'Awesome.  I would prefer getting 3 of my highest priority item though, and maybe you could get 3 of your highest priority item?'

SOLUTION: No

PROBLEM: Context: 'How about you take two water and 1 food and 2 firewood?' 'That's kind of what I was thinking.  That would work for me.' 'OK, great, I forgot my fishing pole so the extra food will really help!'
Utterance: 'The extra firewood will help out keeping the family warm in case the temperature drops.'

SOLUTION:
Yes
