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: 'okay well I will take 2 foods and 2 firewoods then ' 'Thank you so much for understanding, I'm fine with that.' 'I guess that works out good because I need firewood to cook the extra food'
Utterance: 'I get it as you will be having additional packages of food, so I will have only 1 of each'

A: No

Q: Context: 'The main thing I like to do when camping is a lot of hiking (pretty much all day), so I was hoping to get as much food as possible so I can remain active.' 'I'm sure we can come up with a compromise! I understand the need for extra food with exercise. Sometimes I get low blood sugar and need an extra snack. I'll give you 2 food if I can get 1.' 'I think that is a totally fair split for the food. And I actually don't need a lot of firewood. I would be willing to give you all of it in exchange for the water.'
Utterance: 'I think so, too. I'm glad you offered that - we got stuck in the rain and need the firewood to dry our clothes. I'd be more than happy to give you all the water for all the firewood.'

A: Yes

Q: Context: 'yes i guess you too. i will need more supplies like 3 foods, 2 firewood and1 water' 'I have not really camped before so I am looking for as many supplies as possible. What about I get 3 food, 3 firewood, and 1 water. ' 'funnny you but no. so what else will i be left with if i give you those. okay let say i get 2 food, 2 firewood and 1 water.'
Utterance: 'I am really bad at cooking so will probably need an extra good just because I'll ruin one of the 3. Plus Im bringing 2 dogs they can eat the bad food I make 😮 I dont plan on hiking much so how bought I keep all 3 foods, and you keep all 3 waters and we can split the firewood. 2 for me, 1 for you. Great deal!'

Yes
