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 as well. That is good to hear that you like to have bigger fires as we do not care much for that. We would much rather have some extra water.' 'Water is a little important to us too though , if possible maybe we can split that or maybe we can get some more food in replacement.' 'That may be possible.... 🙂 What did you have in mind for the food replacement? '
Utterance: 'You can have all the water if we can have all the food?'
Example Output: No

Example Input: Context: 'I ain't sure if you want 1 or 2 packages of food' 'I would like 2 packages of food' 'As you need 2 of firewood, I think we can have a fair deal like 1-2 of food and firewood or 2-1 of food and firewood.'
Utterance: 'Ok Im thinking I need plenty of food to for my small children. I have a rather large family so there is more of a need. '
Example Output: Yes

Example Input: Context: 'Hi, how are you today'
Utterance: 'Super.  So happy I can fly.'
Example Output:
No
