Special Session on

Argumentation-based Query Answering

at FQAS 2019 (Flexible Query Answering Systems)

July 2-5, Amantea, Italy

Real-world knowledge-based systems must typically deal with information coming from different sources, which leads to uncertain content due to:

Instead of considering such uncertain knowledge useless, knowledge engineers face the challenge of putting it to its best possible use when solving a wide range of problems.

Argumentation is a very useful approach in this setting; essentially, reasons for and against a specific claim are analyzed in order to decide on an outcome. A valuable byproduct of such an analysis is that the conclusion can be accompanied by an explanation, which can be leveraged by users to decide if there is information that should be used differently (i.e., with higher or lower weight, or with different probability), discarded completely, or if there is further information that should be contemplated (i.e., new information, or information that was previously thought to be irrelevant).

Argumentation-based approaches are therefore ideal for flexible query answering systems that contemplate human-in-the-loop models to tackle the challenges of incompleteness and inconsistency in data. Topics of interest include, but are not limited to, the following:

The session is open to contributions generated by specialists in related areas in order to promote interdisciplinary collaborations and cross-fertilization.


Matthias Thimm (University of Koblenz-Landau, Germany)

Talk Title: Algorithmic Approaches to Computational Models of Argumentation


Papers must be submitted through the system found at the conference site, where the name of the session will be found. The length of the papers is up to 12 pages including figures and references, and must follow the template specified at the conference web page (following the LNCS/LNAI format guidelines). See more details at http://www.fqas2019.units.it/#M3

Before submitting their contributions, authors are encouraged to send to the session organizers a statement of interest including full author list, abstract and presenting author.

Important notice: After submitting the paper via Easychair, please notify FQAS PC chairs and session organizers by email of the submission to the special session. In your email, please specify the title and the submission number of the paper submitted to the special session Argumentation-based Query Answering.



Accepted contributions will be published by Springer-Verlag LNAI series and they will be disseminated through the Springer Digital Library Springer Link. Papers will be also indexed by DBLP and Scopus. A selection of the best FQAS 2019 papers will be invited to be revised and extended for the post-conference publication in several special issues of top-quality journals.
