Conjunctive Query Answering in EL using a Database System
نویسندگان
چکیده
We study conjunctive query answering in the description logic EL, the core of the designated OWL2-EL profile of OWL2. In particular, we present an approach that allows the use of conventional relational database technology for conjunctive query answering in EL. This approach is inspired by the OWL support in Oracle Database 11g, semantic technologies.

Conjunctive Query Answering in the Description Logic EL Using a Relational Database System
Conjunctive queries (CQ) are fundamental for accessing description logic (DL) knowledge bases. We study CQ answering in (extensions of) the DL EL, which is popular for large-scale ontologies and underlies the designated OWL2-EL profile of OWL2. Our main contribution is a novel approach to CQ answering that enables the use of standard relational database systems as the basis for query execution....
متن کاملA Practical Approach for Scalable Conjunctive Query Answering on Acyclic EL Knowledge Base
Conjunctive query answering for EL ontologies has recently drawn much attention, as the Description Logic EL captures the expressivity of many large ontologies in the biomedical domain and is the foundation for the OWL 2 EL profile. In this paper, we propose a practical approach for conjunctive query answering in a fragment of EL, namely acyclic EL, that supports role inclusions. This approach ...
متن کاملTractable query answering and rewriting under description logic constraints
Answering queries over an incomplete database w.r.t. a set of constraints is an important computational task with applications in fields as diverse as information integration and metadata management in the semantic Web. Description Logics (DLs) are constraint languages that have been extensively studied with the goal of providing useful modeling constructs while keeping the query answering prob...
متن کاملTemporal Query Answering in the Description Logic EL
Context-aware systems use data collected at runtime to recognize certain predefined situations and trigger adaptations. This can be implemented using ontology-based data access (OBDA), which augments classical query answering in databases by adopting the open-world assumption and including domain knowledge provided by an ontology. We investigate temporalized OBDA w.r.t. ontologies formulated in...
متن کاملQuery Rewriting for Horn-SHIQ Plus Rules
Query answering over Description Logic (DL) ontologies has become a vibrant field of research. Efficient realizations often exploit database technology and rewrite a given query to an equivalent SQL or Datalog query over a database associated with the ontology. This approach has been intensively studied for conjunctive query answering in the DL-Lite and EL families, but is much less explored fo...
