CALL FOR PAPERS
2nd Workshop on Machine Ethics and Explainability-The Role of Logic Programming
July 31, 2022 (ICLP Workshop)
Affiliated with 38th International Conference on Logic Programming (ICLP),
July 31–August 8, 2022, Haifa, Israel
AIMS AND SCOPE
Machine Ethics, Explainability are two recent topics that have been attracting a lot of attention and concern in the last years. This global concern has manifested in many initiatives at different levels. There is an intrinsic relation between these two topics. It is not enough for an autonomous agent to behave ethically, it should also be able to explain its behavior, i.e. there is a need for both ethical component and explanation component. Furthermore, an explainable behavior is obviously not acceptable if it is not ethical (i.e., does not follow the ethical norms of the society).
In many application domains especially when human lives are involved (and ethical decisions must be made), users need to understand well the system recommendations, so as to be able to explain the reasons for their decisions to other people.One of the most important ultimate goals of explainable AI systems is the efficient mapping between explainability and causality. Explainability is the system ability to explain itself in natural language to average user by being able to say, “I generated this output because x,y,z”. In other words, the ability of the system to state the causes behind its decision is central for explainability.
However, when critical systems (ethical decisions) are concerned, is it enough to explain system’s decisions to the human user? Do we need to go beyond the boundaries of the predictive model to be able to observe a cause and effect within the system?
There exists a big corpus of research work on explainability, trying to explain the output of some blackbox model following different approaches. Some of them try to generate logical rules as explanations. However, It is worth noting that most methods for generating post-hoc explanations are themselves based on statistical tools, that are subject to uncertainty or errors. Many of the post-hoc explainability techniques try to approximate deep-learning black-box models with simpler interpretable models that can be inspected to explain the black-box models. However, these approximate models are not provably loyal with respect to the original model, as there are always trade-offs between explainability and fidelity.
On the other side, a good corpus of researchers have used inherently interpretable approaches to design and implement their ethical autonomous agents. Most of them are based on logic programming, from deontic logics to non-monotonic logics and other formalisms.
Logic Programming has a great potential in these two emerging areas of research, as logic rules are easily comprehensible by humans, and favors causality which is crucial for ethical decision making .
Anyway, in spite of the significant amount of interest that machine ethics has received over the last decade mainly from ethicists and artificial intelligence experts, the question “are artificial moral agents possible?” is still roaming around.There have been several attempts for implementing ethical decision making into intelligent autonomous agents using different approaches. But, so far, no fully descriptive and widely acceptable model of moral judgment and decision making exists. None of the developed solutions seem to be fully convincing to provide a trusted moral behavior. The same goes for explainability, in spite of the global concern about the explainability of the autonomous agents’ behaviour, existing approaches do not seem to be satisfactory enough. There are many questions that remain open in these two exciting, expanding fields.
This workshop aims to bring together researchers working in all aspects of machine ethics and explainability, including theoretical work, system implementations, and applications. The co-location of this workshop with ICLP is intended also to encourage more collaboration with researchers from different fields of logic programming.This workshop provides a forum to facilitate discussions regarding these topics and a productive exchange of ideas.
Topics of interest include (but not limited to):
• New approaches to programming machine ethics; • New approaches to explainability of blackbox models; • Evaluation and comparison of existing approaches; • Approaches to verification of ethical behavior; • Logic programming applications in machine ethics; • Integrating logic programing with methods for machine ethics; • Integrating logic programing with methods for explainability.
The workshop invites two types of submissions:
• original papers describing original research. • non-original paper already published on formal proceedings or journals.
Original papers must be formatted using the Springer LNCS style available here:
• regular papers must not exceed 14 pages (including references) • extended abstract must not exceed 4 pages (excluding references)
Authors are requested to clearly specify whether their submission is original or not with a footnote on the first page. Authors are invited to submit their manuscripts in PDF via the EasyChair system at the link:
Paper submission deadline: 10 May 2022
Author Notification: 15 June 2022
Camera-ready articles due: TBA
Authors of all accepted original contributions can opt for to publish their work on formal proceedings. Accepted non-original contributions will be given visibility on the workshop web site including a link to the original publication, if already published.
Accepted original papers will be published (detailes will be added soon).
