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.

Context: 'How many people are in your camping party?' 'i have 6, and 2 more could be joining us to make 8 ' 'Cool! 🙂  It's a good number, we are planning on 10, but you never know on these.  What I do know is this group loves to eat and hike, plus it might get a little chilly.'
Utterance: 'yeah, i understand that. we are all apart of a weigh watchers group ao we'
No

Context: 'I have managed to bring pouches of some of my favorite seasonings.  I'm hoping to find some great wild mushrooms in the forest too.  ' 'I'm a big fan of well seasoned food and mushrooms! Mmm.. 🙂 Do you think it would also be alright for me to have 2 of the 3 waters since I will be hiking a lot?' 'That would be fine.  I was hoping to have 2 but since I am only walking and you are doing more heavy duty hiking, you take them.  Agreed?'
Utterance: 'I really appreciate that. Do you think you will be okay with just 1 water since you have health issues?'
No

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.'

No
