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: 'Yes, I expect that! You need food most and I need water, so let's propose an exact trade? 3 for 3?' 'My main objective for the camp is food and firewood, since I have a large family and the amount of food they give in the camp is very small for all my family and my wife and I have to cook with firewood in the camp.' 'I understand completely. I would like to have all three water, and I'm only traveling with just me, so how about 1 firewood? The rest for you.'
Utterance: 'No me gusta mucho el trato, pero para eso debemos hablar y decidir como adultos un buen trato para los dos. Lo que queremos es disfrutar en el campamento.'
Answer:
No
