- 10 sameAs 10.
- 10 abstract "Designing an ontology for a specific domain is a time-consuming process. In many cases information sources like XML Schemas serve as a basis for ontology engineers to conceptualize the intended ontologies. The ontology design process is sped up significantly when XML Schemas are transformed automatically into generated ontologies. An XML Schema Metamodel Ontology has been designed to represent the components of the XML Schema abstract data model. The generated ontologies’ classes are defined as sub classes of this ontology. The classes specified for the generated ontologies are intended to be further supplemented with additional semantic and domain specific information defined in domain ontologies. The resulting ontologies are as usable as ontologies that were constructed completely manual, but with a fraction of necessary effort.".

- 11 label "Extending Ontologies with Free Keywords in a Collaborative Annotation Environment".
- 11 sameAs 11.
- 11 abstract "Semantic web technologies have introduced the idea of annotating content in terms of concepts taken from ontologies. Since concepts are defined in terms of properties and relations to other concepts, descriptions grow up into larger RDF graphs that can be used as a basis for data integration and intelligent information retrieval. Since ontologies are typically incomplete, it is usually necessary to offer the annotator the possibility to introduce new free keywords or tags in addition to the predefined ontology concepts. The problem then is that free keywords/tags do not have ontological connections to the rest of the RDF graph, unless such relations are defined by the annotator. We present a process for integrating free keywords into the ontological framework, and a practical tool implementation of it, discussing the challenges and possibilities introduced by the system. We also describe a case study performed for the Finnish Defence Forces, where the tool is used for creating a faceted semantic search portal featuring the free keywords and the ontological concepts at the same time.".

- 12 sameAs 12.
- 12 abstract "We consider ontology evolution in a system of light-weight LinkedData ontologies, aligned with each other to form a large ontology system. Whenchanges occur in one of the ontologies, it is difficult for the human editor to keeptrack of what actually has been changed and what modifications may be needed inthe related ontologies in order to keep the system consistent. This paper presentsan analysis toolMUTU, by which such changes and their potential effects to otherontologies can be found. Such an analysis is useful for the ontology editors forundestanding the differences between ontology versions, and for updating relatedontologies when changes occur in other components of the ontology system.".
