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: 'I should be fine, thank you. 🙂 It will be a little bit of work hauling all of my gear and supplies but after I set up camp, it will be smooth sailing.

Utterance: 'Everything looks good.  I'm glad we both got what we wanted.'
[A]: No


[Q]: Context: 'How are you today? Did you have any preferences on the supplies we will be trading?' 'I am good. How about yourself? I think I would like some firewood to start off with. We like to have bigger fires. What about you?' 'I am good as well. That is good to hear that you like to have bigger fires as we do not care much for that. We would much rather have some extra water.'
Utterance: 'Water is a little important to us too though , if possible maybe we can split that or maybe we can get some more food in replacement.'
[A]: No
