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.

Q: Context: 'Hello, well I really need food. Have a lot of extra people.' 'Awesome - same, I also need a ton of food. Will firewood be of interest to you as well? I'll be happy to compensate in this way' 'Firewood is not overly interesting to me, but water is somewhat enticing.'
Utterance: 'Ok, great - I can give you all of my waters in exchange for a majority of the food and half of firewood'

A: No

Q: Context: 'Hi, I am looking at extra items for my camping trip and would like to have 3 firewoods, 3 foods and 2 waters.' 'Hey, I am excited to go camping too! Would you mind sharing your top priority items with me so that we can come up with a fair deal? Ideally I would love 3 firewoods, 3 foods, and 2 waters just like you aha. But perhaps we can each get at least 3 packages of our highest priority item ' 'Hmmm, I think I really need the firewood. I brought softwoods and they burn out quickly so I don't think I'll have enough wood to keep me going through the night. I get kinda scared without the fire. What is your priority?'
Utterance: 'Okay, well firewood is also my top priority since it will be so cold tonight. But I would be willing to take only 1 firewood (and give you 2) as long as I got 2 foods and 2 waters '

A: Yes

Q: Context: 'I too have children who eat like adults they too can't able to withstand hunger so you please show some mercy and give me 3 food packages and take all water and firewood' 'No I need extra food too. I cannot let my children starve and you cant let your children go thirsty. So if you cant agree to share the food i will walk away from the deal.' 'There is no point in walk away. This deal should be done mutually and beneficial for both. So its better I will take 2 food packages, you can take 1 food package, 2 water and 3 fire wood .Hope this will definitely work for you.'
Utterance: 'No i absolutely need 2 food packages and 1 water. How about we do it like this... You take 1 food package, 2 waters and 2 firewoods. Does that work for you?'

A:
No
