6th MEPDaW Workshop at ISWC'20, November 1st, 2020 (virtual event)
The ISWC Organizing Committee and the Semantic Web
Science Association (SWSA) have been closely monitoring
the situation evolving around Covid-19. They have
decided that ISWC 2020 together with its associated
workshops will be virtual events.
We will be providing detailed information in the following days but want to inform you about the following changes:
There are several logistical issues that have to still
be worked out and we would appreciate your patience and
support while we come up with suitable
MEPDaW 2020 needs your support to keep going so please submit papers, participate (remotely) and help us make this (virtual) workshop a success!!
There is a vast and rapidly increasing quantity of scientific, corporate, government, and crowd-sourced data openly published on the Web. Open Data plays a catalyst role in the way structured information is exploited on a large scale. A traditional view of digitally preserving these datasets by “pickling and locking them away” for future use, like groceries, conflicts with their evolution. There are several approaches and frameworks (Linked Data Stack, PoolParty Suite, etc.) that manage a full life-cycle of the Data Web. More specifically, these solutions are expected to tackle major issues such as the synchronisation problem (monitoring changes), the curation problem (repairing data imperfections), the appraisal problem (assessing the quality of a dataset), the citation problem (how to cite a particular version of a dataset), the archiving problem (retrieving a specific version of a dataset), and the sustainability problem (preserving at scale, ensuring long-term access).
This workshop targets one of the emerging and fundamental problems in the Web, specifically the management and preservation of evolving knowledge graphs.
During the past five years, the MEPDaW workshop series has been gathering researchers from the community around these challenges. So far the series successfully published more than 25 research efforts allowing more than 50 individual authors to present and share their ideas.
This workshop aims at addressing challenges and issues on managing Knowledge Graph evolution and preservation by providing a forum for researchers and practitioners to discuss, exchange and disseminate their ideas and work, to network and cross-fertilise new ideas.
Topics of interest include, but are not limited to themes related to the evolution and preservation of Knowledge Graphs:
We envision four types of submissions covering the entire workshop topics spectrum:
The proceedings of the workshops will be published in the CEUR-WS. Papers must be submitted in PDF according to the LLNCS format or in HTML. The PDF files must have all non-standard fonts embedded. Workshop submissions must be self-contained and in English.
All papers should be submitted to https://easychair.org/conferences/?conf=mepdaw2020.
MEPDaW will take place on Sunday 1st of November afternoon between 2pm and 6pm CET. The Zoom link is: https://us02web.zoom.us/j/82782853065?pwd=OG95UzBnYzJ0bmxmMUhFQjZCc1FzUT09 (Meeting Id: 827 8285 3065 - Password: 068321). All hours are Central European Time (CET). (Don't forget to register... ☺)
Sharing, Tracking, and Enhancing Highly Dynamic Knowledge Graphs
Professor Philippe Cudré-Mauroux, eXascale Infolab, University of Fribourg, Switzerland
Abstract: Knowledge Graphs are often seen as static
and complete artifacts. However, my experience with
knowledge graphs shows the exact opposite, i.e., they are
in practice highly dynamic and incomplete. In this talk, I
will give an overview of some of the recent techniques we
developed in my lab to take this fact into account and
improve the automated processing of large-scale and
evolving Knowledge Graphs. I will first describe
data-driven techniques to identify information gaps in
Knowledge Graphs (e.g., in terms of missing classes or
properties). I will then describe a series of methods to
impute missing values from the graphs, before presenting
two large-scale system deployments we were involved in:
one for Swiss open research data, and one for knowledge
tracking on Microsoft Azure.
Bio: Philippe Cudre-Mauroux is a Full Professor and the Director of the eXascale Infolab at the University of Fribourg in Switzerland. He received his Ph.D. from the Swiss Federal Institute of Technology EPFL, where he won both the Doctorate Award and the EPFL Press Mention. Before joining the University of Fribourg, he worked on information management infrastructures at IBM Watson (NY), Microsoft Research Asia and Silicon Valley, and MIT. He recently won the Verisign Internet Infrastructures Award, a Swiss National Center in Research award, a Google Faculty Research Award, as well as a 2 million Euro grant from the European Research Council. His interests are in next-generation software infrastructures for Big Data and AI.
