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 Output: No

Example Input: Context: 'I will submit a deal that might benefit us both.  '

Example Input: Context: 'That make sense. I need firewood though too because I have an autoimmune disease. When it flares up - when it gets too cold - I get very sick and have to go to the hospital. I need to make sure I have enough for the trip as well. I need food to keep my metabolism up so I can make sure my disease stays in check. Why do you want food?' 'That makes sense . I have a friend coming with me on the camping trip, and she also needs to eat, so I'd like to get an extra package of food if possible. ' 'Okay that would be fine. If I can have 3 packages of firewood, you can have 2 packages of food. Does that work?'
Utterance: 'That does not work for me. I need at least one package of firewood. I'm sure you understand, because it seems like we have medical conditions with similar effects. You can take all of the water if I can get 2 packages of food and 1 of firewood. Does that work?'
Example Output:
No
