This paper describes the organization of extracted risk-relevant data in a relational database created at Regulatory Data Corporation for use by security professionals. The initial effort involved creating sets of data-extraction variables around a set of risk relevant keywords. The keywords clustered around events rather than entities and the data extraction variables that were developed cen...
A common problem of ontologies is that their taxonomic structure is often poor and confusing. This is typically exemplified by the unrestrained use of subsumption to accomplish a variety of tasks. In this paper we show how a formal ontology of unary properties can help using the subsumption relation in a disciplined way. This formal ontology is based on some meta-properties built around the fun...
The paper exemplifies the application of two models for ontology description, evaluation and selection. O is a metaontology (an ontology that has ontologies and ontology elements in its domain), based on semiotics, which describes four dimensions of ontologies as communication objects: structural, formal, conceptual, and pragmatical. Starting from a large set, measures have been singled out in ...
This report is a living document of the Research Group Ontologies in Medicine (Onto-Med) which represents work in progress towards a proposal for an integrated system of foundational ontologies. It will be applied to several fields of medicine, biomedicine, and biology, and a number of applications are carried out in collaboration with the Center for Clinical Trials at the University of Leipzig...
This paper presents OntoShare, an automated ontology mapping and merging architecture for learning object retrieval and reuse. The architecture aims to offer contextual and robust ontology mapping and merging through hybrid unsupervised clustering techniques comprising of Formal Concept Analysis (FCA), Self-Organizing Map (SOM) and K-Means clustering incorporated with linguistic processing usin...
Ontology development and maintenance are complex tasks, so automatic tools are essential for a successful integration between the modeller’s intention and the formal semantics in an ontology. In this paper we present a methodology for ontology evolution specifically designed for being used in ontology design tools. It exploits the ontology graphical representation, which is closer to the modell...
One way to detect, monitor and prevent adverse events with the help of Information Technology is by using ontologies capable of representing three levels of reality: what is the case, what is believed about reality, and what is represented. We report on how Basic Formal Ontology and Referent Tracking exhibit this capability and how they are used to develop an adverse event ontology and related ...
