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.

We are scared of fires so we don't want to make campfires.' 'Well maybe we can work something out between us. Our food and water was in the bags they loss so I really need those. Do you think you could make do with 1 food and some water?' 'I really need 2 foods. I can do with 1 water or if you are in a giving mood then maybe I can have 2 waters? 🙂'
Utterance: 'Looks like we both really need the food. If you get 2 food I would need 1 food, 2 water and 3 firewood. '

Answer: No

Question: Context: 'I was more thinking 2 Firewood for me , 1 food and 1 water? The rest would be yours.'

Question: Context: 'Yes, I am! I can't wait. I'm going on a 3 week trip to this gorgeous lake.' 'Wow, 3 weeks is a long camping trip! I don't know if I have enough supplies to go for a trip that long. Are you doing a cabin-style or really roughing it? My husband and son want to do a lot of hiking so we're thinking of moving camp daily.' 'that's awesome! I know, I'm a little worried about my food supplies but I think I can figure everything else out. No, we're roughing it, my boyfriend's huge on camping.'
Utterance: 'Lol, at least it sounds like you've got an expert with you. My husband is really gung-ho but he tends to fly by the edge of his seat when it comes to stuff like planning. He's says he wants to travel light and that he got these water filter straws so that we could drink lake water but I'm super sketched out... I don't want us getting something like schistosomiasis. And I want to make sure everyone stays hydrated with all of the hiking they want to do'

Answer:
Yes
