Part 1. 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.
Part 2. Example
Context: 'That sounds pretty reasonable as I am in need of firewood the most. Would it be most reasonable to each take what we need most and split the water down the middle?' 'Yes, it would.' 'I think that sounds fair. The problem is that there are 3 waters and one of us would get two and the other one. How should we sort that?'
Utterance: 'You can take the two water. I am not that thirsty most days.'
Answer: No
Explanation: In this utterance, the participant does not use self-need since they do not talk about any need for themselves.
Part 3. Exercise
Context: 'Please do understand my situation its very very critical to give 2 food packages to you.Instead you can take 3 waters and firewood too.' 'No that will not work for me given that I have 4 growing children of different ages who eat like adults. I need at least 2 food packages and 1 water. That gives you 1 food package and 2 waters and 3 firewoods.' 'I too have children who eat like adults they too can't able to withstand hunger so you please show some mercy and give me 3 food packages and take all water and firewood'
Utterance: 'No I need extra food too. I cannot let my children starve and you cant let your children go thirsty. So if you cant agree to share the food i will walk away from the deal.'
Answer:
No
