Definition: 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.

Positive Example 1 -
Input: Context: 'I was hoping to get alot of water as well, would you be ok with me getting two waters and three firewoods if you get all the food and one water?' 'Hmm, that's not favorable for me going by the volume of items left in my arsenal. Water is more of a higher priority than food. So, I would exchange 1 pack of food for an additional water' 'So that way you would get two waters and two foods? Those are my priorities as well but i would be ok with it since that way i would get five items and you would get only four.'
Utterance: 'Those are your priorities?? Then that's not fair for you. Then I take 2 water, 1 firewood and 1 food. This is the lowest I can offer'
Output: No

Positive Example 2 -
Input: Context: 'I am doing okay but am in need of some supplies. What about you?' 'Same here. My kids are really looking forward to this. What is most important to you?' 'Firewood! I need it to cook my food and also to stay warm. What about you?'
Utterance: 'That is the same for me as well. My kids were really looking forward to making s'mores and telling stories by the campfire. That's all they've been talking about'
Output: Yes

Negative Example 1 -
Input: Context: 'Hi! How are you doing today?' 'I'm fine. And yourself?' 'Pretty good. I'm really excited about going camping though!'
Utterance: 'Me too. I haven't been camping for several years. '
Output: Yes

Negative Example 2 -
Input: Context: 'Hi, I hope we can work together to get an offer that benefits both of us.🙂'
Utterance: 'I agree! Nice to meet you... I have two boys who always eat! Any chance I canget 2 food?'
Output: No

Now complete the following example -
Input: Context: 'I'm doing fine thank you, how about you? Well for my trip I'm most interesting in socializing so a great campfire a night would be great, I'd prefer not to boil water either so want extra of that too. Food less so as I will go fishing and know wild vegetables, fruits and mushrooms I can pick. How about you?' 'Awesome.. it seems like we're kind of on the same page here then as I'm going to need food for my people since they're not real self-sufficient but I'm less neurotic about the water or the firewood.. we're from Florida so we actually kind of like the cooler weather anyway.. lol' 'Seems like we can come to good terms here. How much of the 3 food packages do you want?'
Utterance: 'So, I'd love to take 2 of the food, 1 of the water, and one of the firewood.. that would leave you 1 food, 2 water, and 2 firewood.. so technically, you're actually netting a higher item count 🙂'
Output: 


Answer: No
