Ontology Functional Dependencies

چکیده
We extend traditional functional dependencies (FDs) for data quality purposes to accommodate ontological variations in the attribute values. We begin by formally defining a novel class of dependencies called ontological FDs, which strictly generalize traditional FDs by allowing differences controlled by an ontology database. The ontology databases contain information about synonyms. We then focus on designing the efficient algorithm for data verification over ontology FDs as well as discuss current and future work.

Extending OWL with Explicit Dependency
Functional Dependency has been extensively studied in database theory. It provides an elegant formalism for specifying key constraints and is the basis for normalization theory used in Relational database design. Given its known axiomatization through logical implications it is expected that the ontology community would be interested in investigating its applicability to conceptual modeling. Th...
متن کاملFunctional Dependencies in OWL ABOX
Functional Dependency (FD) has been extensively studied in database theory. Most recently there have been some works investigating the implications of extending Description Logics with functional dependencies. In particular the OWL ontology language offers the functional property property allowing simple functional dependency to be specified. As it turns out, more complex FD specified as concep...
متن کاملFunctional Dependencies in OWL ABoxes
Functional Dependency has been extensively studied in database theory. Most recently, there have been some works investigating the implications of extending Description Logics with functional dependencies. As it turns out, more complex functional dependencies at the type-level can lead to undecidability, which thus restricts its usage in the TBox. This paper therefore focuses on enhancing its a...
متن کاملDiscovering Ontology Functional Dependencies
Functional Dependencies (FDs) are commonly used in data cleaning to identify dirty and inconsistent data values. However, many errors require user input for specific domain knowledge. For example, let us consider the drugs, Advil and Crocin. FDs will consider these two drugs different because they are not syntactically equal. However, Advil and Crocin are synonyms as they are two different drug...
متن کاملSemi-Automatic Ontology Construction by Exploiting Functional Dependencies and Association Rules
This paper presents a novel semi-automatic approach to construct conceptual ontologies over structured data by exploiting both the schema and content of the input dataset. It effectively combines two well-founded database and data mining techniques, i.e., functional dependency discovery and association rule mining, to support domain experts in the construction of meaningful ontologies, tailored...
