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.

Input: Consider Input: Context: 'I am too.  I am so looking forward to this.  ' 'Yes! I am so on the same page as you. I want to be sure I'm set and prepared. 🙂' 'Would you consider letting me have 2 of the 3 extra firewood?  I have health issues and I get really cold sometimes.☹️'
Utterance: 'Yes, I think that would be very fair, since I don't have health issues myself. Would you allow me to have 2 of the 3 food items? I need energy for hiking. 🙂'

Output: Yes


Input: Consider Input: Context: 'That would work for me if I get all 3 water still' 'How about you get 2 of the waters an i would take 1 of them? I need some water to stay hydrated ' 'If you get two foods then I need more items overall'
Utterance: 'you will have more because you will be getting 2 firewood and i will get ! and you will get 2 waters and i get 1 and i will get 2 foods and you get one'

Output: No


Input: Consider Input: Context: 'Great idea, that works for me. 🙂' 'Okay, let's do that, and then split the food. Since there are only 3, do you want to flip a coin to see who gets 2 of those?' 'That sounds fair, how much food do you feel you need? '
Utterance: 'I would prefer 2 because it's really easy to underestimate how much I could need.'


Output: Yes
