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.

Context: 'I need more food since I have a huge family. Can you give me all food i give you all water?'
Utterance: 'i need a little more food because i forgot that we where staying longer and i forgot some of my food. Can i give you 1 food package please? '
Yes

Context: 'Well, there has to be an item that you need the most. If you tell me what you need the most, we can try to make a deal around it.' 'Oh I see, its going to be THAT kind of negotiation 🙂  Let's just look at it this way.. I'm with a couple other Floridians so we're not really too worried about firewood as we prefer it cooler, anyway.. and we know the lake is nearby that's stocked with trout for eating if necessary (and of course some fresh water's there, too) - so.. I can tell you that I could go totally without Firewood if I needed to.. I'd rather not, but I could.' 'Do you prefer food or water more?'
Utterance: 'Since the lake is nearby enough, I think we'd be more interested in ensuring there's enough food for my people, I think 🙂'
Yes

Context: 'How much firewood and food do you think you need? ' 'Im a vegitarian so food I would like 1 food and for fire 2' 'I think that we can work it out 🙂. We could do something like 2 firewood for you, 1 for me. 2 water for me, 1 for you. And 1 or 2 foods for you, 1 or 2 foods for me. What do you think?'
Utterance: 'That is a kind offer. 🙂 The water is very vital for me. How bout 3 water for me, 0 food for me 3 for you and 1 firewood for me and 2 for you '

No
