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.

Question: Context: 'Good!  How are you?  Ready to go camping?' 'I'm doing well. I can't wait to go camping' 'I am usually not much of a camper!  I will start with an offer if that is ok with you.'
Utterance: 'sure'

Answer: No


Question: Context: 'Yes I do! I was to ask you that in this conversation, will you be Okay with any agreement?' 'Let's see what we are both thinking and negotiate from there. What are your first thoughts on the additional camping packages?' 'I need all the food packing and some basic needs for the camping, may I know about your first though on which you need additional package?'
Utterance: 'I will need food packaging as well, so unfortunately I cannot agree on you taking it all. I will need 2 of the food packages, 1 of the firewood, and 2 of the water as I want to ensure to feed/hydrate my family of 5.. Does this work for you?'

Answer: Yes


Question: Context: 'We can work a deal out. How's your day? 🙂' 'It's good, thank you 🙂 Which package is the most important for you to have on your trip do you think?' 'That would be firewood. Even though is really hot there, it gets cold at night. How's the weather for you? 🙂'
Utterance: 'Ah yes, you'll definitely need some extra wood then! It's also pretty cold here, especially during the night. But I would definitely be willing to let you take 2 firewood in exchange for 3 food. We have a lot of people going and will be out in the middle of nowhere.'

Answer:
Yes
