OntoQualitas is a framework to evaluate an ontology whose purpose is the interchange of information between different contexts. However, the framework does not propose acceptance thresholds of the measure values. In this paper, measures proposed in this framework are redefined in order to improve their usefulness in assessing the quality of such ontologies. These measures were calculated semi-automatically on a set of ontologies and its results were described by means of a statistical analysis as a first step to the definition of their acceptance thresholds.

Ontology evaluation methods generally quantify the quality of the final product. In this paper, based on the measures proposed in OntoQualitas, new guidelines are inferred to evaluate the quality of an ontology in different phases of its life cycle. Evaluating possible errors in these phases allows a better quality, achieved through feedback. Resumen.

Currently, more and more governments publish their data following the doctrine of Open Government. While there are several proposals of how to perform this publication, none of them are complete and, therefore, they can not be easily replicated. The aim of this paper is to be a practical guide for data publication based on a semantic model using the tools afore mentioned. Resumen.

The way in which the semantics of a domain entity is represented in an ontology may differ depending on the requirements that the ontology should satisfy. However, in general the richness is a desired quality attribute for an ontology. The contribution of this paper is a strategy for evaluating and enriching the representation of real entity semantics in a domain ontology. In addition, an application example is discussed.

OntoQualitas: A framework for ontology quality assessment in information interchanges between heterogeneous systems
Computers in Industry, 2014

In such complex networked enterprises, it is increasingly challenging to interchange, share, and manage internal and external digital information. In this context, to achieve interoperability between information systems is a challenging task. In order to solve the interoperability problem at semantic level, several ontology-based approaches have emerged. Although methodologies, methods, techniques, and tools to support the ontology building process were proposed, there are no mature models to measure this process, and the quality of implemented ontologies remains a major concern. This paper presents a framework, OntoQualitas, for evaluating the quality of an ontology whose purpose is the information interchange between different contexts. OntoQualitas includes previous and new measures to evaluate the ontology considering its specific purpose. Additionally, an empirical validation of OntoQualitas is presented.

However, in certain circumstances, they are not enough to efficiently support semantic interoperability due to the lack of context-dependent techniques.

An approach to define semantics for BPM systems interoperability

The semantic model generated allows aligning enterprise’s business processes to support cross-organizational processes by matching the business ontology of each business partner with the EBD ontology. The result is a flexible software architecture that allows dynamically defining cross-organizational business processes by reusing the EBD ontology.For developing the semantic model, a method is presented, which is based on a strategy for discovering entity features whose interpretation depends on the context, and representing them for enriching the ontology. The proposed method complements ontology learning techniques that can not infer semantic features not represented in data sources. In order to improve the representation of these entity features, the method proposes using widely accepted ontologies, for representing time entities and relations, physical quantities, measurement units, official country names, and currencies and funds, among others. When the ontologies reuse is not possible, the method proposes identifying whether that feature is simple or complex, and defines a strategy to be followed. An empirical validation of the approach has been performed through a case study.
