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: 'hello, how do you suggest we share the items?' 'Hi there! Well first I was wondering what item you think you'd like or need the most?'
Utterance: 'I like firewood and water most'
No

Context: 'Hi, I really need water to stay hydrated during my camping trip because my food supplies are low. Do you have any to spare?' 'Hi.  I can't do that right now.' 'Is there anything that you might need? '
Utterance: 'I would be interested in firewood.  Can I ask you, what are your primary concerns on this trip?'
No

Context: 'Yeah. Nice to get out after being inside for most of the spring. This covid-19 crap! wish it would go away.' 'I agree!  I will say it has really sparked my interest in camping and being outdoors even more though! I saw just how connected I was to technology and everything else!' 'I'm up here to do some cross training and noticed that there is some extra water around. Even though the nights are cold I could use some extra water. Do you exercise much?'
Utterance: 'It has been extremely dry in the area I will be going to so I was hoping to get a little extra water too.  I do. I love hiking and running trails!  Due to the extreme dry weather I should have plenty of wood I can scavenge for if you need all of it!'

No
