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: '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.' '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!' 'i too i am bad at cooking and i will spend a longer time in the woods so i will need atleast 2 foods, 2 firewood and 1 water'
Utterance: 'But I have more mouths to feed here so I will give you one of the foods, but then need 2 firewood and then take back 1 of the waters.  '
Example Output: Yes

Example Input: Context: 'hello' 'Hello, there. Should we discuss how to divide up the items for the camping trip?' 'yeah. i need 2 firewood, 1 water and 1 food'
Utterance: 'I need to have 2 or 3 pieces of firewood because I did not pack any way to heat up my food without firewood.'
Example Output: No

Example Input: Context: 'I would be willing to take 2 firewood, 3 food, and 1 water if that would work for you.  ' 'Hmm I think I should take 2 food, 1 firewood, and 3 water. What do you think?' 'Is your first priority the water?  I'm definitely willing to split up by what is most important to us both.'
Utterance: 'Food is actually my first priority but since it seems to be first priority for us both I thought we could split that. Water doesn't seem to be a priority for you so thought I could take that'
Example Output:
No
