Workshop Chairs

Heiko Paulheim

Heiko holds the chair for Data Science at University of Mannheim. His research topics include the creation of large Semantic Web Knowledge Graphs and their use in intelligent applications, as well as ontology matching and learning, intelligent user interfaces for linked data. He leads the development of the RapidMiner Linked Open Data extension, a toolkit for using LOD in Data Mining. For DBpedia, he is working on automatic methods for filling missing statements and removing erroneous statements with heuristic methods. Heiko has co-organized various workshops, including the Know@LOD (Knowledge Discovery meets Linked Open Data) and the LD4IE (Linked Data for Information Extraction) series, has been part of the organizing committee at ISWC and ESWC in various roles, and served as a PC member at major conferences in the field, such as ISWC, ESWC, ACM Hypertext, AAAI, ECAI, WIMS, and I-SEMANTICS, among others.

Harald Sack

Harald is Full Professor of Information Service Engineering at FIZ Karlsruhe, Leibniz Institute for Information Infrastructure as well as at the Institute of Applied Computer Science and Formal Representations (AIFB) at Karlsruhe Institute of Technology (KIT). His main research interests are semantic technologies and knowledge graphs, deep learning, and knowledge mining. He has served as General Chair, PC Chair, Senior PC member or PC member of numerous international conferences and workshops. Harald Sack has published more than 130 scientific papers in peer reviewed international journals and conferences including several standard textbooks. He is founding member of the German IPv6 council and serves as its general secretary since 2009. He has initiated the academic video search engine yovisto.com and is CEO at yovisto. Since 2014 he complements his university teaching with MOOCs on Semantic Web and Linked Data technology at OpenHPI.

Juan Sequeda

Juan is the co-founder of Capsenta, a spin-off from his research, and the Senior Director of Capsenta Labs. He holds a PhD in Computer Science from the University of Texas at Austin. His research interests are on the intersection of Logic and Data and in particular between the Semantic Web and Relational Databases for ontology based data access/integration and semantic/graph data management. Juan is the recipient of the NSF Graduate Research Fellowship, received 2nd Place in the 2013 Semantic Web Challenge for his work on ConstituteProject.org, Best Student Research Paper at the 2014 International Semantic Web Conference and the 2015 Best Transfer and Innovation Project awarded by Institute for Applied Informatics. Juan is the General Chair of 2018 Alberto Mendelzon Workshop on Foundations of Databases (AMW2018), was the PC chair of the ISWC 2017 In-Use track, is on the Editorial Board of the Journal of Web Semantics, member of multiple program committees (ISWC, ESWC, WWW, AAAI, IJCAI) and co-creator of the Consuming Linked Data Workshop series at ISWC. Juan is a member of the Linked Data Benchmark Council (LDBC) Graph Query Languages task force and has also been an invited expert and standards editor at the World Wide Web Consortium (W3C). 

Sebastian Rudolph

Sebastian obtained a PhD in Mathematics from TU Dresden in 2006, before joining Rudi Studer’s Knowledge Management Group in Karlsruhe, where he received his habilitation in Computer Science in 2011. Since 2013, he is a full professor for computational logic at TU Dresden. His main research interests comprise Artificial Intelligence (especially Knowledge Representation and Reasoning), Database Theory, NLP and others. Research stays have led Sebastian to places as diverse as Oxford, Montpellier, Rennes, Santiago de Chile and Vienna. Sebastian is vice president of the Web Reasoning and Rule Systems Association which organizes the RR conference series and the Reasoning Web summer school series. He co-authored several textbooks on Semantic Web technologies. He recently received an ERC Consolidator Grant to support his research on the decidability boundaries of logic-based Knowledge Representation.
