DARE Lab | Apostolos Glenis

I am a PhD candidate at the Department of Digital Systems at the University of Piraeus. From 2019, I will work as a research associate in the Athena Research Center, where part of my responsibilities includes the development of systems for data exploration. This work is part of the INODE European project, funded by the EU's H2020 programme.

I have obtained a Bachelor of Science in Computer Science from the University of Piraeus, followed by a Master of Science in the same field from the University of Crete.

My research interests are primarily focused on Clustering, Data Streams, Machine Learning, and Recommendation Systems.

In this demonstration, we present DatAgent, an intelligent data assistant system that allows users to ask queries in natural language, and can respond in natural language as well. Moreover, the system actively guides the user using different types of recommendations and hints, and learns from user actions. We will demonstrate different exploration scenarios that show how the system and the user engage in a human-like interaction inspired by the interaction paradigm of chatbots and virtual assistants.
