DBpedia ontology enrichment for inconsistency detection

Gerald Töpper, Magnus Knuth, Harald Sack
2012 Proceedings of the 8th International Conference on Semantic Systems - I-SEMANTICS '12  
In order to enable the detection of inconsistencies this work focuses on the enrichment of the DBpedia ontology by statistical methods.  ...  Taken the enriched ontology as a basis the process of the extraction of Wikipedia data is adapted, in a way that inconsistencies are detected during the extraction.  ...  However, in this work the detection of inconsistencies within DBpedia is highlighted, which is achieved by automatic semantic enrichment of the underlying ontology.  ...

ORE - A Tool for Repairing and Enriching Knowledge Bases [chapter]

Jens Lehmann, Lorenz Bühmann
2010 Lecture Notes in Computer Science  
In this article, we present ORE, a tool for repairing and enriching OWL ontologies.  ...  ORE supports the detection of a variety of ontology modelling problems and guides the user through the process of resolving them.  ...  In [28] and [8] , methods for the detection and repair of inconsistencies in frequently changing ontologies were developed.  ...

Based on the PatchR ontology a framework is suggested that allows users to efficiently report and data publishers to handle change requests for their datasets.  ...  Indeed, we see Linked Data consumers equally responsible for the quality of the datasets they use. PatchR provides a vocabulary to report incorrect data and to propose changes to correct them.  ...  Based on an ontology enriched with assertions deduced from statistical evaluation of DBpedia entities (Töpper, have been able to identify inconsistent facts in DBpedia.  ...

Likewise, Inconsistency Checker [4] detects logical inconsistencies in DBpedia using a reasoner based on an enriched ontology model with strict type constraints.  ...  Crowdsourcing is a valuable (and high quality) mean to detect inconsistency of data to the real world. TripleCheckMate [5] have collected erroneous triples in DBpedia.  ...

Collaboratively Patching Linked Data [article]

Magnus Knuth, Johannes Hercher, Harald Sack
2012 arXiv   pre-print
The feasibility of our approach is demonstrated by example of a collaborative game that patches statements in DBpedia data and provides notifications for relevant changes.  ...  Since erroneous data often is duplicated and (re-)distributed by mashup applications it is not only the responsibility of a few original publishers to keep their data tidy, but progresses to be a mission for  ...  Furthermore, inconsistencies for single entities of the DBpedia dataset can be displayed. Patching DBpedia can be regarded as a special case, since this data is based on editable Wikipedia pages.  ...

Universal OWL Axiom Enrichment for Large Knowledge Bases [chapter]

Lorenz Bühmann, Jens Lehmann
2012 Lecture Notes in Computer Science  
This allows to semiautomatically create schemata, which we evaluate and discuss using DBpedia.  ...  In this article, we present a light-weight method to enrich knowledge bases accessible via SPARQL endpoints with almost all types of OWL 2 axioms.  ...  Clearly, in those cases data errors cause problems and our enrichment tool can be used to detect those.  ...

Enriching Wikidata with Linked Open Data [article]

Bohui Zhang, Filip Ilievski, Pedro Szekely
2022 arXiv   pre-print
We evaluate our enrichment method with two complementary LOD sources: a noisy source with broad coverage, DBpedia, and a manually curated source with narrow focus on the art domain, Getty.  ...  We present a novel workflow that includes gap detection, source selection, schema alignment, and semantic validation.  ...  Ontology enrichment deals with noise, incompleteness, and inconsistencies of ontologies, by discovering association rules [8] , or by extracting information from WWW documents [13] .  ...

Detecting hidden errors in an ontology using contextual knowledge

Mehdi Teymourlouie, Ahmad Zaeri, Mohammadali Nematbakhsh, Matthias Thimm, Steffen Staab
2018 Expert systems with applications  
While current ontology debugging methods can detect logical errors (incoherences and inconsistencies), they are incapable of detecting hidden modeling errors in coherent and consistent ontologies.  ...  Our experiments show that adding general ontologies like DBpedia as contextual knowledge in the ontology debugging process results in detecting contradictions in ontologies that are coherent.  ...  Since the dataset enriched the DBpedia ontology, it has the same signature as DBpedia ontology. Therefore, there is no need to use alignment between them.  ...
