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.

Q: Context: 'You can have all the water if I can have all the extra food' 'OK, but first tell me why you need extra food' 'I have 10 people in my group'
Utterance: 'I see. I need more water because I came across some people who were lost and they are very dehydrated.'

A: Yes

Q: 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?'

A: No
