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: 'I would love to have the Firewood the most. ' 'Unfortunately I need firewood the most too. How about I take 2 firewood, 2 food, and 1 water?' 'I feel that I am not getting a fair deal. '
Utterance: 'Then what do you think is fair?'
Example Output: No

Example Input: Context: 'That is a promising bargain but I want at least 2 firewood, it makes for a fun time for my group.' 'Interesting , because my group feels the same way though. How does your group feel about water though?' 'Water is not that important for us but the firewood is a deal breaker for us ☹️'
Utterance: 'I see.... Well we really would like the firewood too though. Could you reconsider it makes a big difference for us.'
Example Output: Yes

Example Input: Context: 'Hi! How about I receive 3 food, 2 firewood, and 1 water?' 'I can't do that. It would leave me with no food at all. How about I take 2 food, and 1 firewood, and 1 water?'
Utterance: 'I really need more food than 1. I am worried about running out. I could take 2 food, and give you 1 food, 2 firewood, and 2 water.'
Example Output:
Yes
