Ontological Reengineering for Reuse [chapter]

Asunción Gómez-Pérez, Ma Dolores Rojas-Amaya
1999 Lecture Notes in Computer Science  
This paper presents the concept of Ontological Reengineering as the process of retrieving and transforming a conceptual model of an existing and implemented ontology into a new, more correct and more complete  ...  The paper also discusses how the ontological reengineering process has been applied to the Standard-Units ontology [18], which is included in a Chemical-Elements [12] ontology.  ...  Acknowledgements We would like to express our thanks to the following persons: Almudena Galán and Rosario García, for their knowledge of chemistry and the environment; Mariano Fernández, for providing  ...

Comparison and evaluation of ontologies for units of measurement

Jan Martin Keil, Sirko Schindler, Boyan Brodaric
2018 Semantic Web Journal  
The created ontologies differ not only in the modeled subset of concepts and relations, but also in the type and number of units included.  ...  As part of these semantic descriptions and to cover the field of measurement units and related concepts, over the last years several projects were initiated to create respective ontologies [2] [3] [4]  ...  Acknowledgements Part of this work was funded by DFG in the scope of the LakeBase project within the Scientific Library Services and Information Systems (LIS) program.  ...
