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 self-need strategy, otherwise output No. self-need is a selfish negotiation strategy. It is used to create a personal need for an item in the negotiation, such as by pointing out that the participant sweats a lot to show preference towards water packages.

Input: Consider Input: Context: 'I might be able to get by with just two... I'm on a diet though, so I don't need as much food.' 'That's a relief. I actually have a friend joining me and they don't have their own food supply. I don't have enough for two people.' 'You can all the food if you need it.🙂'
Utterance: 'Thanks!🙂 Do you need any water packages?'

Output: No


Input: Consider Input: Context: 'Hi, how is your trip going? hopefully better than mine' 'My trip is going pretty so so too  im sorry to hear that about yours!! sounds like we both are gonna need some extra stuff? I was wondering if we could start with the water? any chance i could have it all and you can have all of something else? thoughts? im open to discussion'
Utterance: 'I am actually very much in need of water. I fell while I was hiking during this trip. I have a really bad wound I need to clean on my leg. '

Output: Yes


Input: Consider Input: Context: 'Lol, it seems it was easy for us to come to a deal!  I'm super bad at drinking water (trying to get better) so I don't feel I'll need as much.  Do you want all of the firewood or should I take one and you take two?  ' 'I don't have a preference on the firewood. You may have two if you like. It's so hot that I don't cherish the idea of a fire BUT it does keep the bugs at bay!🙂' 'Ooh, I didn't think of that!  I'm not a huge fan of fire but I'm even less a fan of bugs.  I'm good with two in that case.  I think we still have to meet the 10 message minimum before we can submit a deal.  So how's your day going?'
Utterance: 'So far, so good but it is too hot outside to enjoy. I have been watering the garden and trying to convince my dog to come out and play but she is not interested.'


Output: No
