Peter F. Patel-Schneider on Apr.17 in DKG/SWSA talk series

Dear all,

I am happy to announce the next talk in the online talk series [1] of
the COST Action on Distributed Knowledge Graphs (DKG) [2], in
collaboration with the Semantic Web Science Association (SWSA) [3].

On April 17 at 18:00 CEST / 12:00 EDT, Peter F. Patel-Schneider will
talk about:

 "Does the Semantic Graphs community care about semantics?"


There has been considerable academic progress in providing formal
model-theoretic semantic foundations for Semantic Web languages and
other graph-based formalisms, which all can be characterized as
Semantic Graphs. This work often provides both a well-specified meaning
a particular graph-based formalism and a specification of how to query
this formalism. Nonetheless most work using Semantic Graphs pays little
attention to this body of literature.  Common queries against graph-
based formalisms produce results that are either incomplete or unsound
with respect to either formal or intended semantics of the formalism.
The inadequacy of standard SPARQL to query RDFS data and the common use
of restrictive qualifiers in Wikidata are prime examples of this lack
of attention to even the simplest of semantic foundations.


Peter F. Patel-Schneider received his Ph.D. in Computer Science from
the University of Toronto in 1987. From 1983 to 1988 he was a member of
the Fairchild Laboratory for Artificial Intelligence Research and
Schlumberger Palo Alto Research. Peter then joined Bell Laboratories
and remained there until 2012 when he joined the Nuance Artificial
Intelligence and Language Laboratory. In 2019 he joined the Artificial
Intelligence Center in Samsung Research America. From 2020 until he
retired in 2023 Peter worked at PARC.

Peter's research interests center on representing large-scale knowledge
and information, particularly taking large amounts of data and turning
it into knowledge. He has made long-term contributions to description
and ontology logics, particularly the W3C OWL Web Ontology Language. He
developed much of OWL, as well as SWRL, the Semantic Web Rule Language,
and RDF, the W3C language for representing data in the Semantic Web.

Peter has been working on extracting semantic information from data
sources, allowing data to be more easily integrated into the Semantic
Web. His current life goal is to put Wikidata on a firm semantic
