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.

Doesn't sound like extra water is necessary.  I am in a hot, dry climate.  I can give up all the firewood to you, if you can leave me the three packages of food.  I would also like 2 waters.  ' 'Sorry but I'm willing to give up all the water for 1 food at least. I already mentioned above that I don't plan on hunting or fishing and I plan on being out for a while. That's my final offer.'
Utterance: 'Okay, I will leave you all the firewood and 1 food, and I will take two food and three water packages. I am willing to finalize that.☹️'

Now for food, If we continue with an even split I'd much prefer getting 2 extra food. that would bring us up to a near even split overall ' 'Ok. I get it and that would be fair as I already have enough food.' 'ok thank you. I should be able to get by pretty well with this deal, extra food means I can bring more friends 🙂'
Utterance: 'I'm glad that you are happy with the deal as well.'


Output: No
