Definition: 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.
Input: 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
