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 no-need strategy, otherwise output No. no-need is a cooperative negotiation strategy. It is used when a participant points out that they do not need an item based on personal context such as suggesting that they have ample water to spare. no-need can directly benefit the opponent since it implies that the item is up for grabs.

Q: Context: 'I'm a big fan of well seasoned food and mushrooms! Mmm.. 🙂 Do you think it would also be alright for me to have 2 of the 3 waters since I will be hiking a lot?' 'That would be fine. I was hoping to have 2 but since I am only walking and you are doing more heavy duty hiking, you take them. Agreed?' 'I really appreciate that. Do you think you will be okay with just 1 water since you have health issues?'
Utterance: 'That would be very nice, but I worry about you not having enough on the trail. Dehydration would not be good. I am pretty sure I can ration my supply to make it last. 🙂'

A: Yes

Q: Context: 'Understood! My top two priorities are food and water! Am hoping we can reach a compromise on the items so that we're both happy!' 'That sounds great, I'm the most flexible on food. How many of the extra packages of food do you want?' 'I am hoping to receive 2 packages of food so that way you also have 1. '
Utterance: 'That sounds great to me. I'm hoping to get 2 firewood, 1 water, and 1 food out of the deal. I'm amicable to more discussion though.'

A: No

Q: Context: 'Hello! I am happy to give you two of the waters and one of the fire wood. Would that work for you?' 'I could go for 2 of the waters-I get dehydrated easily so must have those. Would you consider 2 waters and 1 firewood?🙂' 'I would be okay with that, if I can have extra of the food?'
Utterance: 'I really don't need a lot of food when camping so I would be happy to agree to that!🙂'

A:
Yes
