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 there! I am looking to have 3 packages of firewood, 2 packages of food, and 1 package of water please. ' 'Oh we have similar priorities 🙂I am also interested in getting firewood, because I have a condition that makes me very cold, colder than the average person, so I need to make sure I have enough for the trip. Why do you want food' 'That make sense. I need firewood though too because I have an autoimmune disease. When it flares up - when it gets too cold - I get very sick and have to go to the hospital. I need to make sure I have enough for the trip as well. I need food to keep my metabolism up so I can make sure my disease stays in check. Why do you want food?'
Utterance: 'That makes sense . I have a friend coming with me on the camping trip, and she also needs to eat, so I'd like to get an extra package of food if possible. '

SOLUTION: Yes

PROBLEM: Context: 'that will be okay. then I take 2 water you take 1' 'i really need more food. are you sure that we cant do i get 2 foods and i can give you 2 firewoods and 2 water? what do you think?' 'Sorry I can not do with less food'
Utterance: 'okay we can stick to you having 2 and i get 1 correct?'

SOLUTION: No

PROBLEM: Context: 'Okay, sounds good then.  I believe we have a deal then.' 'yes, we have a good deal. you want water from us' 'No, I want firewood and food.  No water.  I want 3 firewood and 2 food.'
Utterance: 'okay, that's great deal we can finalize a deal'
