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.

Ex Input:
Context: 'I'm interested in hearing more about why you want a 2/1 split: Is the food worth more to you than the third firewood? If so, I'm happy to do that split, but I'd like 3 water in return.' 'Okay, like I said I have two growing boys with a very healthy appetite.  They will make my life miserable if they don't have enough to eat.  I would be willing to give you the 3 water.' 'ok, that sounds like a deal. 🙂'
Utterance: 'cool - thank you!  I guess we can submit that then'

Ex Output:
No


Ex Input:
Context: 'Then How about I get two foods, 1 firewood and 1 water?' 'Like i said food is my top priority so i will not do well with less than 2.' 'Then you get two food and no firewood here.😮'

Ex Output:
No


Ex Input:
Context: 'Ah, okay, I could use some of that too! Which one do you need most?' 'water. How about you?' 'I could use water, too, but I'd be willing to give some up if you give me more items overall'
