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: 'I am good. How about you?  Yes, I love camping!' 'I am doing great! camping is super enjoyable' 'Do you bring enough stuff?'
Utterance: 'I have some stuff, but I really need a decent amount of firewood. Gets really cold at night where we camp'
Example Output: Yes

Example Input: Context: 'I can also understand your family situation. I'll give 1 package of water.🙂' 'That works for me.🙂 Are you able to share the food if I give you 1 firewood?' 'I think our dealing is going good. You take all the firewood.As I already said, I have some health issue.  Can you help me with the food?'
Utterance: 'Sounds good I will give you the 2 packages of food.🙂'
Example Output: No

Example Input: Context: 'Ooh rock climbing! I'm definitely scared of heights, so that's out for me. I'm heading to the Puget Sound to camp near the ocean.' 'My wife is from the puget sound. Was just up there a month ago.  I am looking to take the food and water.  We have a large group and will be active.  We will have some hot and dry conditions in the desert. Some are high school age students with big appetites.  What are your preferences.' 'I was definitely looking to have food and firewood most of all. There are plenty of places to collect rainwater and get fresh water in Puget Sound, but we're lacking in food and will need firewood to start a campfire at night.'
Utterance: '😮 I see.  I am wiling to give you the firewood, but I also really need the food.  I could take the waters and two food, and how about if you take the firewood and 1 food? The firewood would be helpful since we need to cook a lot of our food and there is not much to collect in the desert, but if we can take extra food, then it will help solve that problem.🙂'
Example Output:
No
