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 Q]: Context: 'I am running low on firewood. I need more to keep the fire going and cook food. '
Utterance: 'Yeah I need firewood too. It's only 50 degrees at night on the mountain, even in the summer.'
[EX A]: Yes

[EX Q]: Context: 'Hello, are there any of the three items that you want to be sure you have enough of? 🙂' 'I want to be sure that I have enough firewood.  I want to relax, sit around the campfire, and roast hot dogs and marshmallows.  What about you?' 'That sounds great! I like all three items, but I definitely want to make sure I have enough water, especially to drink and stay hydrated and full of as much energy as possible. I require a lot of liquid as a 6-foot-4, 260-pound guy!'
Utterance: 'I don't think the weather is going to be that hot, and I don't plan on doing any hiking.  So, I should need much extra water.'

[EX Q]: Context: 'Don't be nervous. What can go wrong?' 'Well, I haven't gone camping in a number of years, and unfortunately my health has declined a bit. This might actually be my last trip for a while, and I'm afraid of something going wrong. ' 'I'm headed to the mountains. How about you?'
Utterance: 'It's in Upstate New York, near a gorgeous lake. I like it because it's secluded and very peaceful. '
