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.

Q: Context: 'I would be OK with two packages of water.' 'Good. 2 packages of wood for me. 1 for you. 2 packages of water for you, and one for me. How should we divide the food?' 'I will take 2 packages of food and 1 for you.'
Utterance: '😮I thought you didn't need so much food, because of your diet....'

A: No

Q: Context: 'How about if I give you 3 food for 3 waters, and then we split the firewood?' 'I do require at least one water, hiking is very physical demanding. Also there are 3 firewoods?' 'yes there are 3 firewoods.  Okay I understand about the water.  then how about 2 foods for 2 waters, and we somehow divide the three firewoods? 🙂'
Utterance: 'Could I possibly get 2 firewoods? Assuming Water is your high value item?'

A: No

Q: 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. '

A:
Yes
