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: 'Hello! I am very excited!🙂 How about you?' 'Yes!  Would you mind sharing your highest priority item with me?  My most valued item right now is Food actually' 'I am willing to share everything.'
Utterance: 'Awesome.  I would prefer getting 3 of my highest priority item though, and maybe you could get 3 of your highest priority item?'
Example Output: No

Example Input: Context: 'I'm good to give up firewood for more water and food.' 'Thanks!  You can have all the extra food. My pockets are jammed full of munchies.  But water is something it seems we both really need.' 'I'll do 2 water and 0 firewood, 3 food.'
Utterance: 'Hey, good news!  My site is next to a vending machine.  Mostly Ding Dongs and Ho Hos, but there is a bottle of water in there.  I can go with your recommendations.  I'll take three firewood, 1 water, and no food.  But I may be by your site later to borrow toilet paper. OK?'
Example Output: No

Example Input: Context: 'Hello! I'll be camping soon and need to get my hands on some supplies. The food is what I need the most.' 'I'm glad you are joining the camp! I will be bringing my girl scout troop for some badge earning opportunities.' 'Oh my. A whole troop of girl scouts will probably be bringing lots of food with them to share, and plenty of people around to collect firewood. It is going to be just me and my son on this camping trip, his first time.'
Utterance: 'We were planning on getting our outdoor cooking badge by making  a big meal over the campfire tonight. I wll need plenty of firewood for that, but I can manage with only one food.'
Example Output:
Yes
