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.

Example Input: Context: 'What is it that you need?' 'I need food and firewood' 'I need water and then firewood'
Utterance: 'You can have all the water if I can have all the extra food'
Example Output: No

Example Input: Context: 'Okay, I need firewood to stay warm and cook food. I'm willing to give up some water for more firewood.' 'Unfortunately i need the firewood. My body has trouble maintaining heat. I need as much as i can get ☹️' 'Okay, well if you need water and firewood, that only leaves food. If you can part with extra food, here's what I'm proposing'
Utterance: 'Yes you can definitely have all the food. Maybe 2 firewoods and 2 waters for me?'
Example Output: No

Example Input: Context: 'We place a premium on the water.  That's the same amount of water, do you mean we take 3?' 'I do need some extra water.  So I will need to take 1, but our preference is food and we would need firewood to cook it on.  if you're OK with this, I will submit it.  Its a great deal I think and we'll both get what we need' 'my counter then is 2 water, 1 food, and 2 firewood for us and we are set 🙂'
Utterance: 'We're really going to need that extra firewood.  We'll need the heat source, but also for cooking.  It a big deal that I get the extra wood, I hope you will understand why I need it.'
Example Output:
Yes
