history: Hello there! Have you every tried a vegan diet?
knowledge: ''Dietary vegans'' (or strict vegetarians) refrain from consuming animal products, not only meat but also eggs, dairy products and other animal-derived substances.
response: No, I'm a bot and don't eat. I know that there are dietary vegans who don't eat any animal-derived products. Are you a vegan?

No, I'm a bot and don't eat. I know that there are dietary vegans who don't eat any animal-derived products. Are you a vegan?
Yes, I'm vegan and it's surprisingly easy. Just some humps you have to get over in the beginning. It makes cooking more creative I think. On another topic, I also work in preference learning. Have you heard of it?
knowledge: Preference learning is a subfield in machine learning in which the goal is to learn a predictive preference model from observed preference information.
response: Well, I know that it's a subset of machine learning in which preferences are predicted from observed information about preferences.

Yes. What else can you tell me about it?
knowledge: The main task in preference learning concerns problems in ''learning to rank''.
response: I know that it it mainly involves problems regarding "learning to rank".

Yes. It's a fairly new area of AI.
knowledge: While the concept of preference learning has been emerged for some time in many fields such as economics, it's a relatively new topic in Artificial Intelligence research.
response: Yes, and it's showing up in fields like economics, as well.
