TASK DEFINITION: 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 other-need strategy, otherwise output No. other-need is a selfish negotiation strategy. It is used when the participants discuss a need for someone else rather than themselves. For instance, describing the need for firewood to keep the kids warm.

PROBLEM: Context: '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 🙂' 'Sending good luck your way! Any items in particular you need for your trip?'
Utterance: 'Well, I'll start with a trial offer and we'll go from there'

SOLUTION: No
