Turning Informal Thesauri Into Formal Ontologies: A Feasibility Study on Biomedical Knowledge re-Use
This paper reports a large-scale knowledge conversion and curation experiment. Biomedical domain knowledge from a semantically weak and shallow terminological resource, the UMLS, is transformed into a rigorous description logics format. This way, the broad coverage of the UMLS is combined with inference mechanisms for consistency and cycle checking. They are the key to proper cleansing of the k...
متن کاملIncorporating Annotations into Formal and Informal Ontologies: Experiences and Implications
Traditionally, and to a first approximation, annotations can be regarded as comments. In the case of the Web Ontology Language (OWL), this perspective is largely accurate, as annotations are internal constructs included with the language. As internal constructs, annotations in OWL Description Logic (DL) are also constrained to ensure, ultimately, that they do not negatively impact on the ontolo...
متن کاملA content-focused method for re-engineering thesauri into semantically adequate ontologies using OWL
The re-engineering of vocabularies into ontologies can save considerable time in the development of ontologies. Current methods that guide the re-engineering of thesauri into ontologies often convert vocabularies merely syntactically and ignore problems arising from interpreting vocabularies as ontologies, i.e. as sets of statements of facts. Current re-engineering methods also do not make use ...
متن کاملMatching Formal and Informal Geospatial Ontologies
The rapid development of crowd-sourcing or volunteered geographic information both challenges and provides opportunities to authoritative geospatial information. Matching geospatial ontologies is an essential element to realizing the synergistic use of disparate geospatial information. We propose a new semiautomatic method to match formal and informal real life geospatial ontologies, at both te...
متن کاملTurning Information into Knowledge
Lotus Notes, a broad-based software environment tailored for access to distributed databases and electronic communications, has been called the "foundation of a virtual library." Its flexibility and ability to incorporate numerous databases across domains make it a contemporary "microcosm" of how electronic resources can be a tool for organizational learning. Lotus Notes is a particularly rich ...
