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.

Q: Context: 'Same here haha. Is water your lowest priority item too?' 'Yes. We think we have enough water for now.' 'Same here! I am in need of food more than firewood however as I am very hungry. '
Utterance: 'Me too. We have a bigger family and we will run out of food if we don't get some more.'

A: Yes

Q: Context: 'I hear that. What do you think of if I take 3 of the food supplies and you can have two waters? ' 'That sounds like a fair compromise. I can get food by hunting animals, old school style. That would give you 4 total items. In that case it's only fair if I take all 3 of the firewood. 4 for me and 4 for you sounds like a good deal to me. 🙂' 'That sounds fair to me! I don't know the first thing about hunting so that would be a relief on me. We took a bunch of blankets so we'll be good on firewood. 🙂'
Utterance: 'Yep and I need all 3 firewood because I'm hunting. Meat absolutely needs to be cooked. The same cannot be said about pepperoni pizza and chips for example.'

A: No

Q: Context: 'Sure then. You can take all the food. It's not really a priority to me. ' 'Great. So if I have three food and one water, you can have three firewood and two water. Would that work for your trip?' 'That's perfect for my camping trip. '
Utterance: 'Great! Let's make a deal!'

A:
No
