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.

Ex Input:
Context: 'Food is the most important to me because I need to eat more often so that I can take my medications. ' 'Yeah, that is important. I do not have a problem letting you have more food than me.' 'Would it be possible to get an extra water also? How do you feel about the firewood? I wish we could split everything evenly.🙂'
Utterance: 'Me too. Firewood is the most important thing to me. We will be somewhere cold and we could use the extra warmth.'

Ex Output:
Yes

Ex Input:
Context: 'Nice to meet you! I definitely like the idea of having all of the firewood, but water is very important to me. Let's see if we can come to and agreement on how to split up the water.' 'I typically drink a lot of water every day. So I can't agree with much less on that!' 'Alright, I'm sure we can something that works for both of us. The location I'm camping in is only accessible by foot, so I anticipate that I'll need a little more water than normal to feel completely safe. Is there any water source nearby your campsite?'
Utterance: 'Nothing that I would trust. Additionally, I have a dog that will need water as well.'

Ex Output:
Yes

Ex Input:
Context: 'I hear that. What do you think of if I take 3 of the food supplies and you can have two waters? ' 'That sounds like a fair compromise. I can get food by hunting animals, old school style. That would give you 4 total items. In that case it's only fair if I take all 3 of the firewood. 4 for me and 4 for you sounds like a good deal to me. 🙂' 'That sounds fair to me! I don't know the first thing about hunting so that would be a relief on me. We took a bunch of blankets so we'll be good on firewood. 🙂'
Utterance: 'Yep and I need all 3 firewood because I'm hunting. Meat absolutely needs to be cooked. The same cannot be said about pepperoni pizza and chips for example.'

Ex Output:
No
