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: 'Hello, well I really need food. Have a lot of extra people.' 'Awesome - same, I also need a ton of food. Will firewood be of interest to you as well? I'll be happy to compensate in this way' 'Firewood is not overly interesting to me, but water is somewhat enticing.'
Utterance: 'Ok, great - I can give you all of my waters in exchange for a majority of the food and half of firewood'

SOLUTION: No

PROBLEM: Context: 'That doesn't really work for me because then I would get only 2 waters and nothing else ☹️. What do you think is your highest priority?' 'Wood is my highest priority. I need it to stay warm. I'm very cold-natured. What is your highest priority? 🙂' 'Oh that's good. Wood is not my highest priority since I get hot easily lol. My highest priority is probably food because I have a very high metabolism and get very hungry'
Utterance: 'I understand that. I also need food though, because I need the sustenance to help warm me up. So maybe 3 firewood 1 food and 2 waters for me?'

SOLUTION: Yes

PROBLEM: Context: 'Food of course, always snack more when relaxing.  Agree on the hiking.  Out in the woods, we won't have to wear masks!' 'Well we don't want to make all the bears sick though haha. Okay so let's try this... one of us gets 2 waters with 1 firewood and 1 food. I think that's as close as we'll get to equal. You can choose.' 'awe, that's true,  Now I fell bad for the bears.  I'll take 2 waters and 1 food, you can have all the firewood.'
Utterance: 'Okay that sounds great. Have fun!'

SOLUTION:
No
