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 small-talk strategy, otherwise output No. small-talk is a cooperative negotiation strategy. It is used for discussing topics apart from the negotiation, in an attempt to build a rapport with the opponent. For example, discussing how the opponent is doing during the pandemic or sharing excitement for the camping trip.

Ex Input:
Context: 'I think that your reasons are very compelling.  I would also like to survive.' 'Oh, I want you too as well😮' 'Thank you partner!'
Utterance: 'You are welcome.  We both want to have as good an experience and outcome as possible!'

Ex Output:
Yes


Ex Input:
Context: 'No problem.🙂  So I will keep the 3 packages of water and, since I am giving you all 3 packages of the firewood I will take back the 1 food package and keep all 3 of the food packages.' 'I would still like at least 1 package of the food please.  There has been a lot of rain in the area, but I think some poisonous mushrooms maybe prevalent in the area, so to be extra cautious I would like a little spare food on hand.' 'You don't have to eat the poison mushrooms. You can catch some fish from the river or hunt for small animals.  You have all of the firewood so cooking the food should not be a problem.'
Utterance: 'I won't willingly eat the poisonous mushrooms, but it could be very hard to tell the difference from safe and toxic ones.  I understand you will be staying in your area for a few extra days, but can you catch fish or hunt for small animals in your area too?'

Ex Output:
No


Ex Input:
Context: 'That sounds fair to me! So we've got 2 water and 2 firewood for you, 3 food and 1 each water and firewood for me.' 'Yes, you're very kind. I desperately need some more water and firewood.' 'I'm glad we were able to work out something for both of us! I hope you have a great camping trip!'
Utterance: 'Sorry, just adjusting the numbers to what we agreed above! '

Ex Output:

Yes
