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.

Q: Context: 'You drive a hard bargain. I could really use that firewood. It's going to get cold tonight and these sleeping bags are not worth the price I paid ;)' 'Haha, I know but I am in the same situation! ☹️ and since I am getting less food I feel like it is fair I get on more firewood since I truly need that 🙂' 'Some extra water for coffee might keep us warm, would you consider taking 1 food, 2 wood, 1 water?'
Utterance: 'Sure I can do that 🙂'

A: No

Q: Context: 'I would give you all of the additional food if you gave me all of the additional water. ' 'That sounds like a deal' 'Shall we divide the firewood two to one? '

Q: Context: 'Ok, although I was thinking that I could probably find some firewood, but would prefer more water so I don't get dehydrated and can use it to wash and cook.  How about I take 1 firewood, 2 water, and 1 food' 'Good thought on finding your own firewood.  I appreciate the offer of 2 firewood.  I can cut back on water for washing/cooking.  So how about I take 2 firewood, 1 water and 2 food' 'ok that sounds fine🙂'
Utterance: 'Great, thanks for understanding and working with me....and enjoy your first time camping🙂'

No
