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: 'No, I give out only one extra package of food' 'I think you misunderstood what I said. I said that *you* would receive all of the firewood, and two extra packages of food. ' 'ok'
Utterance: 'Ok, great. It was nice negotiating with you.'

Answer: No


Question: Context: 'Wood is my highest priority. I need it to stay warm. I'm very cold-natured. What is your highest priority? 🙂' 'Oh that's good. Wood is not my highest priority since I get hot easily lol. My highest priority is probably food because I have a very high metabolism and get very hungry' 'I understand that. I also need food though, because I need the sustenance to help warm me up. So maybe 3 firewood 1 food and 2 waters for me?'
Utterance: 'I still don't think that is too fair though, since you would be getting 6/9 of the extra items and I would only be getting 3... I'm not an avid camper so I need extra amenities to make sure I survive haha. I am flexible on the water though - maybe we can compromise there. I am fine with you having all of the wood. Maybe we could give you 3 firewood, 1 food, and 1 water?'

Answer: Yes


Question: Context: 'Hello!  I'm looking forward to a big camping trip I've been planning for a long time this weekend.  How about you? Do you have any plans?'

Answer:
Yes
