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.

Context: 'I'm doing pretty well, just preparing for this camping trip.' '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 :) '
Utterance: 'We will likely also need to take water too. Need to be able to wash up.'
Yes

Context: 'Great, how are you?' 'Pretty good, planning my camping trip, checking on supplies.' 'Here too, looks like the weather has changed for us. We won't have enough water to last as we forgot it. Food, we have some snacks, but not enough to get by for our trip. I'm not overly concerned about firewood since it's so hot. But I'm really concerned about water.'
Utterance: 'Yeah, I'm going to the desert so I'm hoping to have enough water. I'm good on food and I hunt for a lot of it anyways.'
Yes

Context: 'I am doing great' 'Great! For our camping trip, I would love to take all the water and firewood. You can have all the food. ' 'I really need the firewood,  It gets very very cold at night where I go camping.'
Utterance: 'I really needed firewood also.  I have brought my whole family camping which includes my 2 and 3 year old.  They really need to stay warm'

Yes
