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 no-need strategy, otherwise output No. no-need is a cooperative negotiation strategy. It is used when a participant points out that they do not need an item based on personal context such as suggesting that they have ample water to spare. no-need can directly benefit the opponent since it implies that the item is up for grabs.

Ex Input:
Context: '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?' 'Since the lake is nearby enough, I think we'd be more interested in ensuring there's enough food for my people, I think 🙂'
Utterance: 'Hmm. I really need food too. I don't care much for water either. How about I take all 3 firewood, 2 food, and 1 water?'

Ex Output:
Yes


Ex Input:
Context: 'hello' 'Hey! How are you? My bestie and I were going to be going on a camping trip, but my other friends heard about it and wanted to come along so we're going to need more supplies than I initially though which has got me a little worried. ☹️' 'Yes!!! I need some water pretty bad.  I am good on food because I fish and I have been able to catch some catfish from the lake.  How about I take 2 water 2 firewood and 1 food'
Utterance: 'I need a lot of food, because of how many people are coming now (like 3 times as many). Also, there's only one stream in the area and it's really far from our campsite, so it would be super inconvenient to have to hike there everyday to refill our canteens. We are in a forest though, so we should be good for wood. Since you can easily fish, what if I take 3 food and 2 water? You can keep all the firewood. 🙂'

Ex Output:
Yes
