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: 'Well, we do need the water pretty badly. But I guess wanting all the water is stingy so I will pack extra water since we are not packing food. How about you guys receive 1 water and 3 food units?' 'If you feel you absolutely need the 3 waters, I will let you have them provided I can have 2 firewoods along with the 3 foods.' 'That is so nice of you. Being that you have family, you might need more firewood for cooking for the crew! Do you agree? And how many kids are you traveling with? '
Utterance: 'I have 2 kids and want to make sure they stay warm.  The firewood will go a long way in keeping them comfortable.'
Yes

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. '
Yes

Context: 'i think i should have 2 waters because i will need to put the fire out to protect the forest.' 'Well, if we can't settle on an agreement i'm going to walk away. We agreed I will get all 3 extra packages of the food but I still wish for the 2 extra wood and 2 extra waters' 'no we agree that you would get 3 food, i would get 3 waters'
Utterance: 'It's agreed, I will get 3 extra packs of food, you will get 3 waters but the extra wood for my kids is needed how about I get 2 extra firewood?'

Yes
