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: 'Interesting.  If I decided to forgo water completely, would you accept giving me everything else?' 'no, at the most i can do is i get 2 water, 2 food and 0 firewood or I get 1 water, 3 food and 1 firewood' 'But you get everything you wanted. You said you needed 3 water, I offered it to you.'
Utterance: 'but i can't give you 3 food and 3 firewood, thats 6 items vs the 3 water'

SOLUTION: No

PROBLEM: Context: 'Firewood, due to the area that we are going to. How about you? ' 'Oh I see. You can have all 3 firewood if you are ok with me taking all 3 food.' 'Hmm, well I'd love to get some of the food. What I took 2 firewood, 1 food and 1 water? '
Utterance: 'Sorry but I really need all 3 food. All the food I brought with me has spoiled because the AC in my car broke. ☹️'

SOLUTION: Yes

PROBLEM: Context: 'I am worried about water but also could use a little more food, just in case. I am looking forward to a nice campfire as well!' 'I know! Camping's so much fun! Where do you plan to be going?' 'We will be camping up north, nothing around for miles!'
Utterance: 'Ooh, that sounds like you're really roughing it! What kind of activities do you plan to do? I'm planning to really tire my kid out and do a lot of hiking. My husband's also excited to practice "survival skills" and wants to do a lot of fishing and foraging too.'

SOLUTION:
No
