Building a Virtual Knowledge Graph from sensor data using Ontop and the PostgreSQL ecosystem

[bcogrel]

What would you like to talk about

In this talk, we will introduce the idea of using virtual KGs (using Ontop) for dealing with sensor data. We will report our first experience with the South Tyrolean Open Data Hub, where all sorts of sensor data were stored in a normalized relational schema using standard PostgreSQL, and discuss the challenges we encountered there. As a closing perspective, we will mention TimescaleDB as the solution for time series storage from the PostgreSQL ecosystem we are now investigating.

All the systems mentioned during the talk are open-source.

Who might be interested in that (technical audience, management, data scientists, etc.)

All of them.

What would you like to know from other participants, what feedback are you looking for

How they deal with sensor data, what are their pain points. How familiar they are with virtual graphs.

What is your background (name, affiliation, etc)

Benjamin Cogrel, co-founder and CTO of Ontopic, core developer of Ontop.

Would you be open to have the session filmed & published later?

Yes
