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: 'Most needed is both food and water. I guess food is my highest priority .🙂' 'Ok perfect, the item I need the most is water because I need to hydrate.  What do you think if I give you 2 food and I keep 2 of water. ' 'Ii understand , the problem  is ctheere is 3 of us. What if  we have 2 food and 2 water and you have 2 firewood ?🙂'
Utterance: 'The object I need the most is WATER, so I cannot give you 2, I am giving you 2 FOOD since it is what you most need. Remember that we must both be satisfied for this to work🙂'
No

Context: 'Hmm.  And why do you need so much food?' 'I need an extra supply of food, as I exercise a lot! 🙂' 'Hmmm.  And the firewood?'
Utterance: 'I get cold easily. I need the firewood to get warm. I might catch a cold.🙂'
No

Context: 'I have a medical condition that causes my veins to close up when I get too cold. I will thus need the 3 firewood.' '☹️Oh, that sounds awful. Are you sure you need all three packages of firewood?' 'I might be able to get by with just two... I'm on a diet though, so I don't need as much food.'
Utterance: 'That's a relief. I actually have a friend joining me and they don't have their own food supply. I don't have enough for two people.'

Yes
