Matching concept descriptions against concept patterns was introduced as a new inference task in Description Logics (DLs) almost 20 years ago, motivated by applications in the Classic system. For the DL EL, it was shown in 2000 that the matching problem is NP-complete. It then took almost 10 years before this NP-completeness result could be extended from matching to unification in EL. The next big challenge was then to further extend these results from matching and unification without a TBox to… 

Matching in the Description Logic FL0 with respect to General TBoxes (Extended abstract)

Matching is the special case of unification where one of the expressions to be unified has no variables and thus remains unchanged under substitutions and both matching and unification have been investigated in detail for the inexpressive DLs FL0 and EL.

Quantitative Variants of Language Equations and their Applications to Description Logics

It is shown that approximate unification in description logics FL 0 can be reduced to approximately solving language equations, and devised algorithms for solving the latter problem for particular distance measures, and acquired a tight complexity bound for the general case.

Weak Subsumption in the EL-Description Logic with Refreshing Variables (Extended Abstract)

This work supports cyclic pattern definitions and considers a new semantics for variables, called refreshing semantics in contrast to the classical (non refreshing) semantics used in the literature, which lies in the valuation of variables that appear in the scope of a terminological cycle.

Dismatching and Local Disunification in EL

It is shown that dismatching can be reduced to local dis unification, and two complementary NP-algorithms for finding local solutions of (general) disunification problems are provided.

Extending Unification in EL to Disunification: The Case of Dismatching and Local Disunification

It is first shown that dismatching can be reduced to local disunification, and then provided two complementary NP-algorithms for finding local solutions of dis unification problems.

Advanced Queries and Explanations

The advanced query faclilities for SPECIAL’s policies and compliance checking address the following two types of problems: 1. given an observed behavior, find the consent that allows that behavior;

Finding Small Proofs for Description Logic Entailments: Theory and Practice (Extended Technical Report)

An approach for generating proofs for expressive DLs based on a non-standard reasoning task called forgetting is developed and implemented and compared the obtained proofs with proofs generated by the DL reasoner ELK, finding that forgetting-based proofs are often better w.r.t. different measures of proof complexity.



Matching in Description Logics

A new approach to performing matching is proposed, based on a ‘concept-centred’ normal form, rather than the more standard ‘structural subsumption’normal form for concepts, so that matching can be performed using arbitrary concept patterns of the description language, thus removing restrictions from previous work.

Matching in Description Logics with Existential Restrictions

This work presents sound and complete decision algorithms for the solvability of matching problems and for computing sets of matchers for matching problems in description logics with existential restrictions.

Polynomial Time Reasoning in a Description Logic with Existential Restrictions, GCI Axioms, and - What Else?

It is shown that even admitting general concept inclusion (GCI) axioms and role hierarchies in ℇL terminologies preserves the polynomial time upper bound for subsumption, and implication of the first result is that reasoning over the widely used medical terminology SNOMED is possible in polynometric time.

A Goal-Oriented Algorithm for Unification in ℇℒℋR+ w.r.t. Cycle-Restricted Ontologies

A goal-oriented NP unification algorithm for EL is extended in two directions: on the one hand, general concept inclusion axioms (GCIs) are added, and on the other hand, role hierarchies and transitive roles are added.

Extending Unification in EL Towards General TBoxes

This paper makes a considerable step towards addressing the problem of unification in Description Logic EL of general concept inclusion axioms, but the GCIs the new unification algorithm can deal with still need to satisfy a certain cycle restriction.

Pushing the EL Envelope

This work will extend the positive result for EL by identifying a set of expressive means that can be added to EL without sacrificing tractability and show that basically all other additions of typical DL constructors to EL with GCIs make subsumption intractable, and in most cases even EXPTIME-complete.

“What’s not in a name?” Initial Explorations of a Structural Approach to Integrating Large Concept Knowledge-Bases

A formal framework for the integration of KBs is set up which enables us to investigate the potential and limits of using structural information (in contrast to just thesaurus information involving identifier strings).

Unification of Concept Terms in Description Logics

This work shows that this inference problem for description logics is of interest for applications, and presents first decidability and complexity results for a small concept description language.

CLASSIC: a structural data model for objects

The kind of language of descriptions and queries presented here provides a new arena for the search for languages that are more expressive than conventional DBMS languages, but for which query processing is still tractable.

Asking Queries about Frames

This paper investigates the algorithms required when answers are deduced by matching queries against a "structural normal form" of descriptions, and introduces a useful refinement of the notion of structural subsumption.
