DKG talks: Olaf Hartig's talk "Reflections on Linked Data Querying and Other Related Topics" on Monday 07/03 18.00CET

Dear all,



Following the previous very successful talk by Ora Lassila and the panel on
20 years into ISWC, on *Monday 07/03 at 18.00 CET,* Olaf Hartig will give a
talk regarding his "Reflections on Linked Data Querying and Other Related
Topics".



The talk will be streamed at the YouTube channel of the Distributed
Knowledge Graphs (DKG) COST action:
https://www.youtube.com/channel/UCQQDtAXkngxHfqLyzr_D6Zg

You can find more information about the talk bellow and at the action’s
website: https://cost-dkg.eu/talks



Kind regards,

Anastasia



*About the speaker*: Olaf Hartig is an Associate Professor at the
Department of Computer and Information Science of Linköping University..
Additionally, he is an Amazon Scholar working with the Neptune graph
database team at Amazon Web Services. Olaf is interested in problems
related to the management of databases and knowledge, with a focus on graph
data and data that is distributed over multiple, autonomous and/or
heterogeneous sources. He received the 2019 SWSA Ten-Year Award for a paper
which pioneered the idea of traversal-based query execution as well as
querying Linked Data on the Web in general, and for his PhD thesis on the
foundations of Linked Data queries, he was honored with the SWSA
Distinguished Dissertation Award in 2015.

*About the talk*: When aiming to evolve the World Wide Web into a Web of
interlinked data ready for software agents and applications to consume and
act upon, Semantic Web researchers have advanced the state of the art of
federated data management, with novel ideas that focus on discoverability,
interoperability, and automation. While the adoption and the practicality
of these ideas did, generally, not pan out as expected or hoped for, core
aspects of the ideas have the potential to be carried over as key
ingredients of new approaches to interact with decentralized knowledge
graphs and to build decentralized data architectures. In this talk I will
reflect on these earlier ideas and describe research problems that need to
be addressed in order to carry these ideas forward.
