OVERVIEW

In recent years, the explainability of complex systems such as decision 
support systems, automatic decision systems, machine 
learning-based/trained systems, and artificial intelligence in general 
has been expressed not only as a desired property, but also as a 
property that is required by law. For example, the General Data 
Protection Regulation’s (GDPR) „right to explanation“ demands that the 
results of ML/AI-based decisions are explained. The explainability of 
complex systems, especially of ML-based and AI-based systems, becomes 
increasingly relevant as more and more aspects of our lives are 
influenced by these systems‘ actions and decisions.

Several workshops address the problem of explainable AI. However, none 
of these workshops has a focus on semantic technologies such as 
ontologies and reasoning. We believe that semantic technologies and 
explainability coalesce in two ways. First, systems that are based on 
semantic technologies must be explainable like all other AI systems. In 
addition, semantic technologies seem predestined to support rendering 
systems that are not based on semantic technologies explainable.

Turning a system that already makes use of ontologies into an 
explainable system could be supported by the ontologies, as ideally the 
ontologies capture some aspects of the users‘ conceptualizations of a 
problem domain. However, how can such systems make use of these 
ontologies to generate explanations of actions they performed and 
decisions they took? Which criteria must an ontology fulfill so that it 
supports the generation of explanations? Do we have adequate ontologies 
that enable to express explanations and enable to model and reason about 
what is understandable or comprehensible for a certain user? What kind 
of lexicographic information is necessary to generate linguistic 
utterances? How to evaluate a system‘s understandability? How to design 
ontologies for system understandability? What are models of 
human-machine interaction where the system enables to interact with the 
system until the user understood a certain action or decision? How can 
explanatory components be reused with other systems that they have not 
been designed for?

Turning systems that are not yet based on ontologies but on sub-symbolic 
representations/distributed semantics such as deep learning-based 
approaches into explainable systems might be supported by the use of 
ontologies. Some efforts in this field have been referred to as 
neural-symbolic integration.

This workshop, the second workshop on semantic explainability, aims to 
bring together international experts interested in the application of 
semantic technologies for explainability of artificial 
intelligence/machine learning to stimulate research, engineering and 
evaluation – towards making machine decisions transparent, re-traceable, 
comprehensible, interpretable, explainable, and reproducible. Semantic 
technologies have the potential to play an important role in the field 
of explainability since they lend themselves very well to the task, as 
they enable to model users‘ conceptualizations of the problem domain. 
However, this field has so far only been only rarely explored.
