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.

Ex Input:
Context: 'Hello fellow camper! I am interested to know your preference in items?' 'Hello! Yes I'm excited for the trip. 🙂 My most important is food. How about you?' 'I am excited too. I really need food too. What other item is priority for you?'
Utterance: 'I also need water because we plan to do a lot of hiking. What about you?'

Ex Output:
Yes


Ex Input:
Context: 'I meant I would give you my firewood, what would you trade in return?' 'Oh sorry for the confusion. 😮 In that case, thank you for the generosity! 🙂 How about if I have 3 firewood, 1 food, and 1 water?' 'I can do that for 3 food and 3 water?'
Utterance: 'I think we're close. Let's shake hands on this: 3 firewood, 1 food for me, and then 2 food and 3 water for you. I'll make sure your food packages have extra doggy treats! 🙂 Is that a deal?'

Ex Output:
No


Ex Input:
Context: 'I can't swim too. I think two waters will help me to survive on this trip and I will need at least two firewood to make fish or other food items for my family. ' 'You don't need this water to swim.  You can take two of the food if you're worried about food.  I will take two water and two firewood since I have a large family to nourish and keep warm.  Your initial suggestion of 3  waters and firewood is laughable.  Please provide a realistic compromise.' 'If I take two waters, 1 firewood, and 2 food supplies, this will help me during the trip. It seems as if you are more skilled than I am on a camping trip. Please consider my request☹️'
Utterance: 'LOL - not a chance.  You're going to have to give me more than that.  I am more skilled and thus need firewood.  How about this...I will take 3 firewood and 2 food.  You can take all the water because you're so non-skilled in the wilderness. I am going to hunt for my food, but again I have a large family.  I am not considering your request  at all.  We will need to come to a decision relatively soon.'

Ex Output:

Yes
