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: 'I need   food and water the most . There are 3 of us.🙂' 'Your most needed item is water or food?' 'Most needed is both food and water. I guess food is my highest priority .🙂'
Utterance: 'Ok perfect, the item I need the most is water because I need to hydrate.  What do you think if I give you 2 food and I keep 2 of water. '

Ex Output:
Yes


Ex Input:
Context: 'Yah we have a few things planned. One of the things they are looking forward to is reading scary stories by the campfire and making s'mores' 'That sounds like a lot of fun. What do you think you will need for that experience?' 'We likely need a lot of firewood and some water to put out the fire when we are done lol. What are you thinking?'
Utterance: 'Yea, I'm not too into firewood because it will be quite hot when I make my camping trip. I could definitely use some more food just in case of an emergency out there.'

Ex Output:
Yes


Ex Input:
Context: 'Hello I would like to have two bottles of water and in trade will take 1 food and firewood for a higher amount of water.' 'Hello. I would consider giving you 2 waters for 3 firewood and 2 food. I have a large family so the additional firewood will help with warmth and cooking food. 🙂' 'That sounds like you could  really use the extra warmth for your family'
Utterance: 'Yes it is very much needed. My family doesn't have a lot of extra bedding so having the warmth of a fire will help make sure we don't get cold at night 🙂'

Ex Output:

Yes
