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.

We currently don't have enough for our trip.' 'Everything is negotiable 🙂 but if you absolutely can't budge on the food then I will need some extra firewood and water to make up for it.'
Utterance: 'We cannot budge at all on food. But are more then happy to give up all the extra fire wood for all the food. '
No

Context: 'I do require at least one water, hiking is very physical demanding. Also there are 3 firewoods?' 'yes there are 3 firewoods.  Okay I understand about the water.  then how about 2 foods for 2 waters, and we somehow divide the three firewoods? 🙂' 'Could I possibly get 2 firewoods? Assuming Water is your high value item?'
Utterance: 'Sure, we can do that'

No
