A software measurement task ontology

Monalessa Perini Barcellos, Ricardo de Almeida Falbo
2013 Proceedings of the 28th Annual ACM Symposium on Applied Computing - SAC '13  
Aiming at establishing a common conceptualization regarding the software measurement process, we developed a Software Measurement Task Ontology (SMTO), which is grounded on the Unified Foundational Ontology  ...  This task ontology was developed to be used for addressing semantic interoperability problems arising from the jointly use of different measurement-related standards, as well as for supporting semantic  ...  This paper presents a task ontology for the software measurement process.  ...

What Makes a Good Ontology? A Case-Study in Fine-Grained Knowledge Reuse [chapter]

Miriam Fernández, Chwhynny Overbeeke, Marta Sabou, Enrico Motta
2009 Lecture Notes in Computer Science  
Understanding which ontology characteristics can predict a "good" quality ontology, is a core and ongoing task in the Semantic Web.  ...  This task is of increasing importance for a set of novel Semantic Web tools, which perform fine-grained knowledge reuse (i.e., they reuse only appropriate parts of a given ontology instead of the entire  ...  , to task-based evaluations of a single ontology or a collection of ontologies.  ...
