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: 'Hi there, good to connect with you. How are you today?' 'I am good, thank you.  What are your preferences? I really need the extra food packages.  We are doing a lot of hiking and mountain biking and there are no grocery stores for at least 50 miles.🙂' 'Oh wow that is quite a lot of hiking! I think we will be hanging out a lot overnight and so I am looking for more firewood if possible. My kids can't hike very far and want to do more with smores and marshmellows. '
Utterance: 'I can work with that.  I am willing to give you all of the firewood.  We are in a hot climate and won't need too much.  Being in a hot climate and with a lot of exercise, I am hoping to take the three water packages. '
answer:
Yes


question:
Context: 'ME as well! we are a group of big eaters, and are looking to take lots of food.' 'That is fair as there is no showers or sinks at my campsite so I am looking to take water :) ' 'We will likely also need to take water too. Need to be able to wash up.'
Utterance: 'That is fair, I also will need a good bit of firewood to keep warm as the campsite is in a colder area.'
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
