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: 'Yes I do! I was to ask you that in this conversation, will you be Okay with any agreement?' 'Let's see what we are both thinking and negotiate from there. What are your first thoughts on the additional camping packages?' 'I need all the food packing and some basic needs for the camping, may I know about your first though on which you need additional package?'
Utterance: 'I will need food packaging as well, so unfortunately I cannot agree on you taking it all. I will need 2 of the food packages, 1 of the firewood, and 2 of the water as I want to ensure to feed/hydrate my family of 5.. Does this work for you?'
Example Output: Yes

Example Input: Context: 'Sounds good I will give you the 2 packages of food.🙂' 'So nice of you !! Now can you summarize your needs?' 'I will need 3 packages of firewood. 1 package of food and 1 package of water. What are your needs?'
Utterance: 'Yes, you are absolutely right. Thank you very much !! I'll take 2 package of food and 2 package of water .'
Example Output: No

Example Input: Context: 'I would like the 3 food packages because my sister forgot to pack any food items for the trip. You can have all the water and firewood. ' 'Oh no! I have my daughter with me and she really likes to eat. I was hoping to get at least some of the food. Do you need water or firewood more?' 'I'm sure we can come to some compromise. I know my sister and I want to make s'mores in the evening. How about I get 2 food and 1 firewood, 1 water and you get the rest? '
Utterance: 'I love s'mores. Food is my number one concern though. If I'm only getting 1 of the food I really need all of the water. How does that sound?'
Example Output:
No
