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: 'Hi! I'm going camping soon with my family at a lake! We're looking forward to it so much since we haven't been able to get out due to Covid. Are you going camping too?' 'Yes! I am also going with my family. My husband and I are essential workers but his hours all got cut. I got laid off from my job for part of the time.' 'oh man that sucks ☹️! I know Congress is currently debating all of the unemployment stuff too. Where do you plan to be going camping?'
Utterance: 'We didn't get unemployment or a stimulus check. ☹️ We are planning a trip to Missouri, Lake of the Ozarks. Our younger children have been cooped up so long we are hoping to let them get some sun and swimming in!'
Example Output: No

Example Input: Context: 'Seems like we can come to good terms here. How much of the 3 food packages do you want?' 'So, I'd love to take 2 of the food, 1 of the water, and one of the firewood.. that would leave you 1 food, 2 water, and 2 firewood.. so technically, you're actually netting a higher item count 🙂' 'That is a very fair deal. Sure you could join us at our campfire if you wanted some heat.'
Utterance: 'That would be awesome.. I'm looking forward to it.  Glad we could come up to such an amicable and easy arrangement 🙂'
Example Output: No

Example Input: Context: 'Sending good luck your way! Any items in particular you need for your trip?' 'Well, I'll start with a trial offer and we'll go from there' 'Ok, offer away!'
Utterance: 'Well, food is high on my to do list only because I have a big family and we all know how they eat..... Wood well, I can find that along the way if necessary, and same as water so both of those are fairly low on my list... you?'
Example Output:
Yes
