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.

Ex Input:
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'

Ex Output:
Yes


Ex Input:
Context: 'Hello I'm interested in obtaining more of the water and food, but don't need any extra firewood🙂' 'Well I am really in the same position as you are. Suppose I take 2 waters and only 1 food? ' 'I get really sweaty when I hike, so I really need to get at least 2 of the waters.'
Utterance: '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. 🙂'

Ex Output:
Yes


Ex Input:
Context: 'Firewood is definitely important as well! Last time I went camping we ran out pretty fast, so I want to be extra prepared. 🙂' 'Oh no! I can see why that would be extra important to you! I will give you two of the firewood for two of the water' 'That sounds good to me! I think since water is pretty important on a camping trip (especially with a baby!), and since you are getting 2 extra packages of water, may I ask that I get 2 of the food packages? I have 2 (always hungry) preschoolers joining us haha! 🙂 I can never seem to keep them full'
Utterance: 'I wish there was a way to split that third package of food in half because I am so worried for my husband's diabetes, he constantly needs food as well ☹️'

Ex Output:

Yes
