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: 'No, of course not. You can have the extra of those if you'd like. It is really the water that is the most important to me. ' 'Hmmm... I don't really need the firewood,just the food which you are offering and the water. ' 'Okay, can I have the 2 waters and 2 firewood then? I will give you all of the food, and 1 of the water. Do you need any firewood at all?'
Utterance: 'Since carrying the extra would could make your dehydration worse, I'll take any firewood you don't want. But I'll give you the 2 waters and firewood then for the 3 food and 1 firewood. Deal?'

Ex Output:
No


Ex Input:
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 🙂'

Ex Output:
Yes


Ex Input:
Context: 'Hmm, okay, that sounds reasonable. How does 3 water, 2 food and 1 firewood for me, and all the rest for you sound?' 'Im goign to need all the firewood I can get. They want to cook smores on it. How about you get 3 water 2 food and I get 3 firewood and 1 food. I think that is very fair and would help us both out. 🙂🙂' 'That sounds like a very reasonable deal, I understand how girls can get with their snacks haha. I'm okay with giving up all the firewood. You said you need at least some of the food, right?'
Utterance: 'Thanks. Yea they do  love their snacks LOL. Yea I just need 1 extra food. Snice I wasn't planning on her friend coming. '

Ex Output:

Yes
