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: 'It's nice to know the firewood is not important to your camping trip. I'm glad I can have all the firewood to myself. How do we get to share the other resources. ' 'Actually, I think I may need more food than water. How about I take the food and we can split the water. You may have 2 waters, if you need them.' 'Sure then. You can take all the food. It's not really a priority to me. '
Utterance: 'Great. So if I have three food and one water, you can have three firewood and two water. Would that work for your trip?'
No

Context: 'Yeah I'm hoping to relax with my family and enjoy the outdoors ' 'Same, i do ask though as i have a medical condition if i can have all the water, it is really hard for me to stay hydrated' 'oh that is tough. I am also looking for water. I need it to cook our food and it is going to be extra hot and I need to keep my family hydrated'
Utterance: 'May i atleast have 2? I can get siezures if i dont get enough hydration'
Yes

Context: 'Hello, I am very cold and need food and wood to remain warm. How about I get 3 firewood, 3 food and 1 water?' 'That doesn't really work for me because then I would get only 2 waters and nothing else ☹️. What do you think is your highest priority?' 'Wood is my highest priority. I need it to stay warm. I'm very cold-natured. What is your highest priority? 🙂'
Utterance: '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'

Yes
