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.

Example Input: Context: 'How about if I give you 3 food for 3 waters, and then we split the firewood?' '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? 🙂'
Utterance: 'Could I possibly get 2 firewoods? Assuming Water is your high value item?'
Example Output: No
