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.

Question: Context: 'Hmm, okay, that sounds reasonable. How does 3 water, 2 food and 1 firewood for me, and all the rest for you sound?' 'Im goign to need all the firewood I can get. They want to cook smores on it. How about you get 3 water 2 food and I get 3 firewood and 1 food. I think that is very fair and would help us both out. 🙂🙂' 'That sounds like a very reasonable deal, I understand how girls can get with their snacks haha. I'm okay with giving up all the firewood. You said you need at least some of the food, right?'

Question: Context: 'Yes, I am! I can't wait. I'm going on a 3 week trip to this gorgeous lake.' 'Wow, 3 weeks is a long camping trip! I don't know if I have enough supplies to go for a trip that long. Are you doing a cabin-style or really roughing it? My husband and son want to do a lot of hiking so we're thinking of moving camp daily.' 'that's awesome! I know, I'm a little worried about my food supplies but I think I can figure everything else out. No, we're roughing it, my boyfriend's huge on camping.'
Utterance: 'Lol, at least it sounds like you've got an expert with you. My husband is really gung-ho but he tends to fly by the edge of his seat when it comes to stuff like planning. He's says he wants to travel light and that he got these water filter straws so that we could drink lake water but I'm super sketched out... I don't want us getting something like schistosomiasis. And I want to make sure everyone stays hydrated with all of the hiking they want to do'
