instruction:
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 self-need strategy, otherwise output No. self-need is a selfish negotiation strategy. It is used to create a personal need for an item in the negotiation, such as by pointing out that the participant sweats a lot to show preference towards water packages.
question:
Context: 'Hello, well I really need food. Have a lot of extra people.' 'Awesome - same, I also need a ton of food. Will firewood be of interest to you as well? I'll be happy to compensate in this way' 'Firewood is not overly interesting to me, but water is somewhat enticing.'
Utterance: 'Ok, great - I can give you all of my waters in exchange for a majority of the food and half of firewood'
answer:
No

question:
Context: 'I think they went to Chicago. I really needing replace our lost water and sleeping bags. I see there are some extra supplies to share. I could really use the water and firwood. 🙂' 'oh yeah, you definitely do. we have all of our stuff and mostly wanted to hike and have picnics during our camping trip ' 'Great. If you mainly doing picnics do you want 3 Food? I could use the the supplies. 🙂'
Utterance: 'Sure, I'll take 3 food and 1 water would be nice. you can have 2 waters and all of the firewood '
answer:
Yes

question:
Context: 'The main thing I like to do when camping is a lot of hiking (pretty much all day), so I was hoping to get as much food as possible so I can remain active.' 'I'm sure we can come up with a compromise! I understand the need for extra food with exercise. Sometimes I get low blood sugar and need an extra snack. I'll give you 2 food if I can get 1.' 'I think that is a totally fair split for the food. And I actually don't need a lot of firewood. I would be willing to give you all of it in exchange for the water.'
Utterance: 'I think so, too. I'm glad you offered that - we got stuck in the rain and need the firewood to dry our clothes. I'd be more than happy to give you all the water for all the firewood.'
answer:
Yes
