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: 'I get really sweaty when I hike, so I really need to get at least 2 of the waters.' 'My friend is joining me tomorrow so there will be two of us. I really need the extra water so we both can stay hydrated. You can have all the food and 2 of the firewood packs if I get 2 of the water packs. 🙂' 'I understand, but I don't need any extra firewood.  You could have 2 food, 3 firewood, and 1 water?🙂'
Utterance: 'Well I am going to have to think about this deal. Perhaps I can contact my friend and see if he can get some extra water. He is a big eater so the food may come in handy. '

A: Yes

Q: Context: 'I can give out the food in exchange for the firewood' 'Okay. I need all of the water, if you're getting the firewood. ' 'I can't give out all the water. I need to be hydrated as well. '
Utterance: 'You already have all the basics, though, so you won't lack sufficient water to be hydrated. I have a serious medical condition that requires that I have access to additional water. '

A: No

Q: Context: 'I have a big party with varying degrees of health and I'm going to need every bit of firewood and food I can get my hands on!  🙂' 'hi, we may be in luck then, i really would like water as i enjoy walking and hiking, i will require some firewood though so i can roast some s'mores' 'How many people are in your camping party?'
