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 elicit-pref strategy, otherwise output No. elicit-pref is a cooperative negotiation strategy. It is used to discover the preference order of the opponent in the negotiation.
Part 2. Example
Context: 'What do you think if in the camp we get together and have a meeting between your family and mine? We can have a small party to get to know each other better.' 'Sounds great!' 'Ok, my proposal is to give you all the firewood you need, on the condition that you give me all the water I need. And regarding food we can negotiate.'
Utterance: 'That sounds good. What do you propose on the food?'
Answer: No
Explanation: The primary utterance does not try to elicit information on the preference order of the participant. So this is correct.
Part 3. Exercise
Context: 'That sounds amazing and delicious! maybe we can compromise? Maybe, I can get all 3 waters and you can have all 3 Foods? what do you think? ' ' I would agree to that if I can also have two things of firewood. I am going to need a lot of wood, so I can cook the meals I am making 🙂' 'I completely understand, thank you for compromising with water and food. Wished we had 4 firewoods to divide and share it equaly, may I ask how long will you be camping for? Im afraid I need 2 firewoods as well, maybe we can see who has the greater need? '
Utterance: 'I am going to be camping for a couple of weeks, so I will need quite a bit. I also realized some additional water would be good, because I have some meals that need me to boil water. Maybe you can have 2 firewood in exchange for me having one of your waters? Then you would still have plenty of water, but also plenty of firewood 🙂'
Answer:
No
