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: 'Ooh rock climbing! I'm definitely scared of heights, so that's out for me. I'm heading to the Puget Sound to camp near the ocean.' 'My wife is from the puget sound. Was just up there a month ago.  I am looking to take the food and water.  We have a large group and will be active.  We will have some hot and dry conditions in the desert. Some are high school age students with big appetites.  What are your preferences.' 'I was definitely looking to have food and firewood most of all. There are plenty of places to collect rainwater and get fresh water in Puget Sound, but we're lacking in food and will need firewood to start a campfire at night.'
Utterance: '😮 I see.  I am wiling to give you the firewood, but I also really need the food.  I could take the waters and two food, and how about if you take the firewood and 1 food? The firewood would be helpful since we need to cook a lot of our food and there is not much to collect in the desert, but if we can take extra food, then it will help solve that problem.🙂'
Output: 


Answer: No
