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 feel for firewood we dont need as much, as we are going to be camping, with that means, in my opinion, with branches and brush available, maybe we can take 2 fire woods, what do you think?' 'Since I got some food already, can I get 3 water, 2 firewood and 0 food then?' 'can we do at least one food? if thats okay with you? I would like to have extra food in case something happens, i will be able to have the extra supplies. '
Utterance: 'ok, so list out the amount you need'
No

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: 'Wow...what a different world' 'You got that right I can give you 2 firewood if you give me two food' 'What abou you give me two firewoods and i give you 1 food and 1 water?'
Utterance: 'two firewood 1 food and two water my little boy does not know how to ration water '

Yes
