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: 'Well you wanted the firewood so take it or leave it.' 'Can we do 5 - 4? and 2 fire wood , 1 food and 1 water for me?' 'No😡'
Utterance: 'Please its really unfair... The items are still in your favor. My family really needs the firewood and some additional water and food would make our day so much better. You are still coming out on top with excess supplies.'
Example Output: Yes

Example Input: Context: 'i cant afford to give you all 3 waters because i would need some for myself' 'I completely understand, I have a large family coming along, I really need the extra supplies, as for the food and firewood are you okay with the amount? ' 'i am an avid water drinker. i can afford to give you 2 water for three firewood though'
Utterance: 'I have alot of children, and those little rascals can chug water like there is no tomorrow, will you allow me to get the 3 waters and you can have 2 firewood and and 3 foods, what do you think?'
Example Output: Yes

Example Input: Context: 'Hi, I will need alot of water as I need it to stay alive.' 'I agree, with camping i feel there are many uncertainties. Finding clean water would be too difficult, best to take as much water as possible. ' 'I will also need some Firewood too to start a fire'
Utterance: 'I feel for firewood we dont need as much, as we are going to be camping, with that means, in my opinion, with branches and brush available, maybe we can take 2 fire woods, what do you think?'
Example Output:
No
