In this Computer Science course, you will study conversational agents. You will learn about the history and different types of chatbots, their status quo and applications, and the challenges associated with building a powerful conversational agent. You will build your own chatbots using an open-source framework, evaluate its performance, and improve it by contributing your own software components. Over the course of the semester, we will meet both creators and customers of conversational agents throughout Berlin, one of Europe's tech startup capitals.
