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.

Example Input: Context: 'okay how about if i only get 2 food packages and i give you 2 firewood. So we both gets something to help us/ Because i to at least 1 firewood' '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 '
Utterance: 'If you get two foods then I need more items overall'
Example Output: No

Example Input: Context: 'I have a medium amount of water so I would like some more. I wish we had lots of supplies to split up evenly but I'm sure we can work it out🙂' 'I agree! We can figure out working out a deal! What if I gave you 2 food and 2 waters and you gave me your wood and one of food/water? If that doesn't work for you we can also figure something else out.' 'I think that sounds reasonable. Of course, I could counter with I take 2 food, 2 waters and 1 firewood. What do you think of that?'
Utterance: 'That is also good. This is hard to work out since it's uneven haha. What about if I give you all my food, you give me all your firewood, and then I can give you 2 waters? I think that'd be more fair for you. '
