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 other-need strategy, otherwise output No. other-need is a selfish negotiation strategy. It is used when the participants discuss a need for someone else rather than themselves. For instance, describing the need for firewood to keep the kids warm.

Context: 'I am walking away, completely unfair' 'You haven't offered anything and walking away means you get nothing so that doesn't seem like an option' 'You can have ALL the water, and 1 firewood'
Utterance: 'If you want two firewoods, i will need some of the food. My family maybe cold, we can't be cold and hungry. I need at least 1 food '
Yes

Context: 'I like firewood and water most' 'Hmm okay, I am willing to give you three waters! I was hoping to get 3 firewood though, as it's going to be really cold where I am going.' 'seems like we have same priority items. firewood. I also need firewood most because I am prone to pneumonia '
Utterance: 'Oh no, I'm so sorry to hear that ☹️ Let me ask about the food first then, would you be willing to give me the 3 packages of that? I am going to have a lot of people with me and we won't be near any stores at all.'
Yes

Context: '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.' '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? 🙂' '😮Sound good enough but since you know i can not do without having anything to sustain me whenever i am thirsty then i suggest you are free to take TWO of the water and since your food has also been stolen by bears and you don't make much left, then you can have the TWO of the food items too and leave the THREE firewood for me with ONE food. How does that sound? 🙂'
Utterance: 'I think we are getting very close to a good deal. Would you be willing to give me ONE firewood in case the stuff I have gets wet?'
No
