==================

We are pleased to announce the workshop Logical approaches to handling INconsistent DAta (LINDA), which will take place on July 24, 2026 in Lisbon, as part of KR 2026 and thus of FLoC 2026.

CONTEXT AND MOTIVATION

It is widely acknowledged that real-world data is plagued with quality issues, including false and/or outdated information. A common method for detecting erroneous facts is to employ database constraints or domain knowledge, typically expressed in some logic-based formalisms. Once inconsistencies have been detected, one may either modify the data in order to restore consistency or reduce the level of inconsistency, and/or employ inconsistency-tolerant semantics in order to be able to return meaningful answers to queries despite the contradictory information. There is an extensive body of work on handling inconsistent data, which was developed initially within the database community but has subsequently grown into a prominent topic among knowledge representation and reasoning (KR) researchers, particularly in the context of ontology-based data access. However, despite notable advances, there still remains much to be done to obtain practical and robust inconsistency-handling methods and to develop scalable implementations. Moreover, there is a real need to bring together different groups and subareas working on the topic to exchange experiences. Indeed, there is much to gained from bridging research conducted in the database, KR, and Semantic Web communities, as well as across different KR subareas. The interest in doing so can be witnessed by several recent results showing how repairs of databases and knowledge bases can be related to argumentation and belief change, as well as by transfers of results between the database and KR settings. Furthermore, the development of effective tools will necessarily rely upon advances issuing from the automated reasoning community, notably, SAT solvers, answer set programming systems, rule engines, and ontology reasoners.

AIMS AND SCOPE

The LINDA workshop aims to bring together groups of researchers from different communities who are interested in developing principled logic-based methods for tackling inconsistent data, in order to share recent advances, discuss open challenges, and exchange experiences. A non-exhaustive list of topics in the scope of the workshop is the following:

- database and knowledge base repairs
- inconsistency-tolerant semantics (e.g. repair-based and paraconsistent semantics)
- inconsistency measures
- explanations of inconsistencies or query answers over inconsistent data
- incorporating qualitative or quantitative preferences
- probabilistic, possibilistic, and neuro-symbolic approaches to handling inconsistent data
- inconsistency handling for temporal and/or spatial data
- handling other forms of imperfect data (e.g. incompleteness, imprecision, uncertainty, entity resolution)
- connections to other KR areas (e.g. argumentation, logic programming, non-monotonic reasoning)
- implementations of inconsistency handling approaches

We also welcome contributions and participation from researchers working on closely related topics, whose experience may contribute to achieving robust methods for handling inconsistent data.

WORKSHOP FORMAT

The program will feature two invited talks, given by:

* Leopoldo Bertossi, Carleton University, Canada & IMFD, Chile
* Thomas Eiter, TU Wien, Austria

as well as number of contributed presentations, which will be selected by the program committee.

SUBMISSIONS

We invite extended abstracts (2-5 pages long, excluding references, in CEURART style) related to the aforementioned topics. Note that as the main aim of the workshop is to promote discussion, we welcome not only contributions reporting on unpublished results or ongoing work, but also extended abstracts that summarize previous publications that fall within the workshop scope.
