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: 'How are you today? Did you have any preferences on the supplies we will be trading?'
Utterance: 'I am good. How about yourself? I think I would like some firewood to start off with. We like to have bigger fires. What about you?'

A: Yes

Q: Context: 'It sure is..So how much food do you need for the trip? Do you need firewood to cook the food? Thank you for understanding my issues. 🙂' 'I definitely need the food the most. I'm definitely not a "hunter", so if I were to run out, I'd be in pretty sad shape. I do need the firewood for both cooking, and keeping warm. It gets cold at night where we're going. How about youself?' 'Well since we were already given a few supplies before this deal, I was wondering if you could give me all 3 water, and I could give you all the firewood and 2 of the food packages. I only say all the water because we already have some and my medical condition sucks. lol I wish we could camp together! we seem to be a good match. lol! 🙂'
Utterance: 'I wish that too 🙂 And I 100 percent understand the need for water, but I don't know if I can go with only what I have so far. What if I only took 1 water, and you take 2? I hate to take any because I do understand you need it, but I really can't go without any  ☹️'

A: No
