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.

Ex Input:
Context: 'ME as well! we are a group of big eaters, and are looking to take lots of food.' 'That is fair as there is no showers or sinks at my campsite so I am looking to take water :) ' 'We will likely also need to take water too. Need to be able to wash up.'
Utterance: 'That is fair, I also will need a good bit of firewood to keep warm as the campsite is in a colder area.'

Ex Output:
Yes


Ex Input:
Context: 'Hello, I would like to take all of the firewood and two of the water packages. You can take all of the food and the other water package. ' 'I am not a fan of that deal'
Utterance: 'That's alright. Do you have anything you need in particular? '

Ex Output:
No


Ex Input:
Context: 'Hi There, I'm doing okay with my preparations but I am worried that I don't have enough food or water for the next few days.' 'I also worried about those two items, especially water.' 'Yes, they say it supposed to be really hot the next few days.'
Utterance: 'yes, how do you suggest we share these resources?'

Ex Output:
