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.

Example Input: Context: 'Hi 🙂 I'd like to have more water because the location that I'm going to is really dry. I'll need water to stay hydrated.' 'Sure you can give me firewood in place of water'
Utterance: 'Thank you 🙂 That works for me. I'm also in my first trimester so I'll need a bit of extra food since I'm feeding my little one. Is that alright with you?'
Example Output: No

Example Input: Context: 'Okay! You can have all the water. I want all the food.' 'yeah sure, I will share with you all the food. What is about firewood?' 'You can have two if I can have one if you're okay with that.'
Utterance: 'My place is so cold, so I want all the firewood for save my children from cold.'
Example Output: Yes

Example Input: Context: 'Splitting the food is what I was thinking as well, but I'd also like to split the firewood. We can split the water or I'm fine taking all of that.' 'I would be willing to take 2 firewood, 3 food, and 1 water if that would work for you.  ' 'Hmm I think I should take 2 food, 1 firewood, and 3 water. What do you think?'
Utterance: 'Is your first priority the water?  I'm definitely willing to split up by what is most important to us both.'
Example Output:
No
