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: 'I need a minimum of 2 firewood. You can have 2 water. I would now like 2 food.' 'It seems we both have a big need for firewood. 😮 If you insist on 2 firewood, then I insist on getting 2 water AND 2 food along with 1 firewood.' 'I insist on 2 firewood 🙂. I would be happy to let you have 2 water. Are you sure you need 2 food?'
Utterance: 'Yes. If I'm letting you have more firewood (of which I would like to have more) then I'm going to need more of the other supplies. 🙂'

Ex Output:
No


Ex Input:
Context: 'Well hopefully it will be cooler up in the mountains. What supplies are you in need of?' 'I am a big eater. I tend to eat a lot throughout the day. You? 🙂' 'Ha I get that! I'll need that too, but mostly water because my family wants to do a lot of hikes.'
Utterance: 'Thirty I see. No problem, we'll work something out. 🙂'

Ex Output:
No


Ex Input:
Context: 'Hi. I'm most interested in water. What's your highest priority?'
