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.

[EX Q]: Context: 'I am doing quite well myself. Why are you camping today?' 'Well my sister and her husband are celebrating their anniversary this weekend so we volunteered to watch her daughters. We decided it would be fun to take her kids and ours camping! What about you? 🙂' 'That is really nice of you! I hope they have fun! My family had this trip planned for quite awhile. We have an extra person with us because my son begged me for his friend to come. I couldn't say no. 🙂'
Utterance: 'I have definitely been there before! With taking all the kids I'm worried about them getting dehydrated. I also have a 7 month old that needs water to make her bottles! I was hoping to get 3 extra packaged of water for sure. '
[EX A]: Yes

[EX Q]: Context: 'Hmmm...I'm pretty muddy due to clumsiness, so I may need one extra. I could give you two waters and all of the firewood. What do you think? 🙂' 'So are you suggesting that I would get 2 waters, 3 firewood, and no food?' 'Right! Well, beyond the food you already have. '
Utterance: 'I have an extra person camping with us that I didn't expect when I bought food, so I could use one if you're willing 🙂'
[EX A]: Yes

[EX Q]: Context: 'Hello there.' 'hi' 'So I plan to go hiking a lot this trip and I would appreciate a majority of the water and firewood if possible.'
Utterance: 'I want to go on hiking too. Since I don't go alone I need food and water.'
