Reference excerpt

Pascal Hitzler is a German American computer scientist specializing in Semantic Web and Artificial Intelligence. He is University Distinguished Professor, endowed Lloyd T. Smith Creativity in Engineering Chair, one of the Directors of the Institute for Digital Agriculture and Advanced Analytics (ID3A) and Director of the Center for Artificial Intelligence and Data Science (CAIDS) at Kansas State University, and the founding Editor-in-Chief of the Semantic Web journal, the Neurosymbolic Artificial Intelligence journal, and the IOS Press book series Studies on the Semantic Web.

Education Hitzler received a Diplom in Mathematics from the University of Tübingen in Germany in 1998. He has a PhD in Mathematics from the National University of Ireland, University College Cork, 2001.

Career Hitzler received the title of 2018 Brage Golding Distinguished Professor of Research during his tenure at Wright State University, where he was endowed NCR Distinguished Professor. From 2004 to 2009 he was first Wissenschaftlicher Mitarbeiter (as postdoc) and then Akademischer Rat at the Institute for Applied Informatics and Formal Description Methods at the University of Karlsruhe in Germany. Between 2001 and 2004 he was a postdoctoral researcher at the International Center for Computational Logic at TU Dresden. From 1999 to 2001 he was a PhD student at the Department of Mathematics at the National University of Ireland, University College Cork, and graduated with a dissertation on "Generalized Metrics and Topology in Logic Programming Semantics." From 1992 to 1998 he studied Mathematics and Computer Science at the Eberhard-Karl University of Tübingen in Germany and graduated with a Diplom thesis on "Topology and Logic Programming Semantics". Hitzler co-founded several series of academic meetings, including the Workshop on Neural-Symbolic Learning and Reasoning (NeSy, since 2005, which since 2023 is a conference), the Web Reasoning and Rule Systems Conference (RR, since 2006), the Workshop on Applications of Semantic Technologies (AST, 2007-2011), and the U.S. Semantic Technologies Symposium (us2ts, since 2018). He also contributed to steering the Workshop on Ontology Design & Patterns (WOP, since 2017). Hitzler has published several books as author and editor, including the textbook "Foundations of Semantic Web Technologies" which was awarded an Outstanding Academic Title award in 2010 by the Choice Magazine. A scientometric publication in PLOS Biology, in October 2020, listed him among the top 1% of scientists world-wide in Artificial Intelligence & Image Processing. At the 2020 International Semantic Web Conference, he and his co-authors received the SWSA Ten-Year Award by the Semantic Web Science Association, for the publication Prateek Jain, Pascal Hitzler, Amit P. Sheth, Kunal Verma, Peter Z. Yeh, Ontology Alignment for Linked Open Data. Hitzler is also one of the authors of the OWL 2 Web Ontology Language Primer, which is a W3C standard.

Worked examples

Example 1 — a first encounter with Pascal Hitzler

Start with the simplest possible case. Write down what Pascal Hitzler claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pascal Hitzler before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pascal Hitzler ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pascal Hitzler

In research: Pascal Hitzler appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Pascal Hitzler in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Pascal Hitzler is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of the Karlsruhe Institute of Technology, Alumni of University College Cork, Alumni of the National University of Ireland, so understanding it makes those chapters shorter.
In everyday life: Look for Pascal Hitzler outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
