TASK DEFINITION: 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.
PROBLEM: Context: 'Hi there! How are you?' 'Hello good morning I'm well thank you.' 'Let's talk about what we need. First, I don't eat meat, so I really feel like I'd need a little extra food, as I couldn't hunt or forage for food at all. I feel like I could survive without a ton of water, but would need water, as I hike a lot and cant trust any sources'
Utterance: 'I've also planned my trip to include a lot of hiking and so I have a high priority for extra water, as like you've said you need to stay hydrated on your hike and you can't trust any source. How can we divide up the water as that seems to be the number one priority for us both.'

SOLUTION: Yes

PROBLEM: Context: 'i suggest we put excess in charge of working on proposition because prevention of excess is not a good first step.' 'I don't know what you mean by "prevention of excess." Can you clarify?' 'what i mean by prevention of excess is that we should focus on getting excess and not to limit it regardless of what we already have because if we should offer some creative approaches by excess. we can both come to an agreement if you are interested.'
Utterance: 'Okay. Lets just try to do some negotiation. I am the most interested in getting more WATER. The water I already have at the campsite looks dirty so, if it is okay with you, I would like all THREE of them. My food has also been stolen by bears and I don't make much left, so I would like TWO of the food items. You can have all the firewood and the other food item. How does that sound? 🙂'

SOLUTION: Yes

PROBLEM: Context: 'I think we'll both need each of the three items, but we can't split them evenly. How about I take 2 waters, 2 firewoods, and a food. You can have two food packages, a water, and a firewood.' 'hi bro, 2 water for 2 firewood 1 food for me'
Utterance: 'Do you need the extra water? I get super thirsty and I'd be willing to give up another firewood to get an extra water, while we still get at least one of each.'

SOLUTION:
Yes
