TASK DEFINITION: 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.
PROBLEM: Context: 'I really need water because I take medication that requires drinking a lot of water. The firewood I dont need to much off and I need very little food as I am dieting. lol 🙂' 'I totally understand that. And it's pretty important, lol ' 'It sure is..So how much food do you need for the trip? Do you need firewood to cook the food? Thank you for understanding my issues. 🙂'
Utterance: 'I definitely need the food the most. I'm definitely not a "hunter", so if I were to run out, I'd be in pretty sad shape. I do need the firewood for both cooking, and keeping warm. It gets cold at night where we're going. How about youself?'

SOLUTION: Yes

PROBLEM: Context: 'Happy birthday to your dad!! You can have all of the food if I can have all of the water. 🙂' 'That' 'Will that work for you? If so, we can talk about the firewood. 🙂'
Utterance: 'Sorry, submitted too early! That sounds good to me! If I can have all the food, you can take 2 of the firewood and I'll take one. Plus you take all of the water.'

SOLUTION: No

PROBLEM: Context: 'Okay that is a deal. I would like 3 water as well because my campsite water is very dirty. I would like to have bottled water to take my medicine with and we forgot to pack it.' 'I may consider 2 waters as we are going to be hiking up the tallest mountain in North Carolina and they say temps may reach 100, I must have some have at minimum of 1 package of water.' 'okay, two waters would be great. So its a deal.'
Utterance: 'So let me recap, I will get two fire woods, 1 food and 1 water, You would get 1 fire wood, 2 food and 2 water. You know you really are getting a fantastic deal, you are so lucky that I am desperate for that wood.'
