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. I am looking to have one package of water and on package of food.' 'Is there any way you could let us have 3 packages of each? I'm just trying to make sure my family has enough, we don't get to get out in the woods that often. It's really important to us.' 'Well, I need 1 package of each.'
Utterance: 'One package of each might be doable--I thought you said you only needed one package of water and food? Can I get 3 packages of firewood at least? That's easily the most important to us, I don't want anyone getting a cold weather injury.'

SOLUTION: Yes

PROBLEM: Context: 'I don't need much firework, so you could have two packages. Could I take all of the water so I can wash my clothes? ' 'Sure, I can wash whatever that needs to be washed out in the lake or river. 🙂' 'Alright, can you repeat the deal with me so we can make sure we are on the same page? '
Utterance: 'ok, I am getting 1 food package, two packages of firewood, and all of the water. Is this correct? '

SOLUTION: No

PROBLEM: Context: 'hello' 'Do you have a preference for any extra items for your camping trip?' 'yes. i need 2 pack of firewood, 2 pack of water and 1 pack of food'
Utterance: 'I need 3 packs of firewood, 2 packs of food and 3 packs of water. My husband and I are diabetic, so we're cold-natured, need regular meals and hydration.'

SOLUTION:
Yes
