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.

Example Input: Context: 'Yes, we are all looking forward to it. Thanks for being amenable and trying to make this work. That might be okay, but could we take take the 3 packages of food? Since we won't be doing as big of a bonfire, I am sure we'll hike more or swim and need the extra energy' 'I was hoping to take at least some of the food with me.  As you know, those teenagers seem to hungry ALL the time.  It's like feeding fuel into a bottomless pit.  So I'm definitely going to need some of the food for my trip as well.' 'Hm okay. Would 1 packet of food be sufficient? I know they are growing but my friends are ex football players and can eat 3x the normal person'
Utterance: 'Those ex-football players can eat way more than the average person.  I would be OK with that deal.  I will get 2 firewood, 1 water and 1 food.  You'll get 1 firewood, 2 water and 2 food.  I'll go ahead and submit this deal for you to agree to.  Thanks for negotiating and have a great camping trip!'
Example Output: Yes

Example Input: Context: 'Hi, how are you today?' 'I'm good! I'm looking forward to my camping trip this weekend. How about you?' 'I'm good as well, I hope the weather works with me 🙂'
Utterance: 'Sending good luck your way! Any items in particular you need for your trip?'
Example Output: Yes

Example Input: Context: 'Being that you're getting 2 of 3 of the item (food) that for me is the highest value, I think it's only fair that I get all 3 of the medium value items (firewood) and one of the low value item (water). That would give me 5 packages and you 4 packages, but 2 of 4 of your packages are the high value items.' 'Okay then. I agree with you.. Shall we finalize our deal. I will take the 2 packages of food and 2 packages of water.r.🙂' 'Yes, I find that an acceptable deal.'
Utterance: 'Okay. Nice to meet you. Have a nice day🙂'
Example Output:
Yes
