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.

Q: 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 '

A: Yes

Q: 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.'

A: Yes

Q: Context: 'Me too! It will be great to finally get out of town for a few days. I mostly need more firewood to keep the wife nice and toasty. How about you?' 'oh it turns out I need firewood too!🙂' 'Ha what a surprise! ;-) What do you need second most?'
Utterance: 'I need food to feed all my friends that are coming up. how about you?'
