The 2019 LWDA conference has been held in Berlin from September 30th to October 2nd, 2019. This year’s venues have been the Smart Data Forum (next to the TU Berlin) in and the Berlin School of Library and Information Science (next to the main building of the Humboldt-University Berlin). The conference is organized by the German Computer Science Society (GI). The core topics of the conference are Knowledge Discovery and Machine Learning; Databases, and Information Retrieval.

CC IRML presented current research in the domain of chatbot systems. Our contribution "An Information Retrieval-based Approach for Building Intuitive Chatbots for Large Knowledge Bases" reports the experiences running the Virtual Assistant "Bobbi". Bobbi is a chatbot providing information related to services and locations of the Berlin Administration. The paper discusses how to build chatbots without training data (cold-start problem) and explains how to efficiently handle the wide variety of observed user intentions. The research uses data which we have collected in the live system deployed on the official website of the city of Berlin ( We presented the results in a 30 minutes talk. Besides, we participated in the poster session to discuss more directly with attendees.
