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: 'Great idea, that works for me. 🙂' 'Okay, let's do that, and then split the food. Since there are only 3, do you want to flip a coin to see who gets 2 of those?' 'That sounds fair, how much food do you feel you need? '
Utterance: 'I would prefer 2 because it's really easy to underestimate how much I could need.'
Example Output: No

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 too have children who eat like adults they too can't able to withstand hunger so you please show some mercy and give me 3 food packages and take all water and firewood' 'No I need extra food too. I cannot let my children starve and you cant let your children go thirsty. So if you cant agree to share the food i will walk away from the deal.' 'There is no point in walk away. This deal should be done mutually and beneficial for both. So its better I will take 2 food packages, you can take 1 food package, 2 water and 3 fire wood .Hope this will definitely work for you.'
Utterance: 'No i absolutely need 2 food packages and 1 water. How about we do it like this... You take 1 food package, 2 waters and 2 firewoods. Does that work for you?'
Example Output:
Yes
