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.

Context: 'I am doing good. Thanks. Which item do you need the most?' 'I was thinking firewood, because the most fun I have camping is roasting marshmellows and hanging out around there. How about you?' 'Oh hmm. I really need extra firewood because I forgot to bring a sleeping bag. I will be freezing to death at night. ☹️'
Utterance: 'Okay, well tell me what you need the least of, if you don't mind.'
Yes

Context: 'Hello there I'm well. How about yourself?' 'I'm good. I'm excited for the camping trip. I have been planning this for a few weeks. I'm excited to get out into the woods.' 'Oh great! I love getting out into nature.'
Utterance: 'Do you have any preferences in regards to the firewood, food, and water? I would like us both to get what we need.'
Yes

Context: 'Hi, I appreciate your response. I would like to compromise. I will give you the bundle of firewood you requested as well as the 2 packages of food. However, I would like to get 2 jugs of water. I have 2 other adults with me on this trip and they require more water to stay hydrated than a baby would.' 'That actually sounds pretty good to me. 🙂' '🙂'
Utterance: 'So, it looks like we have reached a compromise. '

No
