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: 'No me gusta mucho el trato, pero para eso debemos hablar y decidir como adultos un buen trato para los dos. Lo que queremos es disfrutar en el campamento.' 'I do not understand spanish. Please speak to me in English.' 'Sorry I'm practicing my Spanish for the camp. I do not like the deal very much, but for that we must talk and decide as adults a good deal for both of us. What we want is to enjoy in the camp.'
Utterance: 'By giving you all three food and 2 of the three firewood, you're definitely getting much more than I am.'
Example Output: No

Example Input: Context: 'Hello! I'll be camping soon and need to get my hands on some supplies. The food is what I need the most.' 'I'm glad you are joining the camp! I will be bringing my girl scout troop for some badge earning opportunities.'
Utterance: 'Oh my. A whole troop of girl scouts will probably be bringing lots of food with them to share, and plenty of people around to collect firewood. It is going to be just me and my son on this camping trip, his first time.'
Example Output:
Yes
