Applying the ONTOMETRIC Method to Measure the Suitability of Ontologies
Business Systems Analysis with Ontologies
In the last years, the development of ontology-based applications has increased considerably, mainly related to the Semantic Web. Users currently looking for ontologies in order to incorporate them into their systems, just use their experience and intuition. This makes it difficult for them to justify their choices. Mainly, this is due to the lack of methods that help the user to determine which are the most appropriate ontologies for the new system. To solve this deficiency, the present chapter proposes a method, ONTOMETRIC, which allows the users to measure the suitability of existing ontologies, regarding the requirements of their systems. ONTOMETRIC, based in the analytic hierarchy process, can be used to select the mostappropriate ontology among various alternatives. This chapter describes the main techniques and activities to apply the method.
Selection of Ontologies for the Semantic Web
Lecture Notes in Computer Science, 2003
The development of the Semantic Web has encouraged the creation of ontologies in a great variety of domains. Web users currently looking for ontologies in order to incorporate them into their systems, just use their experience and intuition. This makes it difficult for them to justify their choices. Mainly, this is due to the lack of methods that help the user to measure that the most appropriate ontologies for the new system are. To solve this deficiency, this work proposes a method which allows the users to measure the suitability of the existent ontologies, regarding the requirements of their systems.
Population of a Method for Developing the Semantic Web Using Ontologies
Advanced Topics in Database Research, Volume 4
At present, the Web offers available information to people in diverse ways. With the initiative of Semantic Web, the aim is to make the content of Web pages available in a way that allows people and computers to "understand" this information following frameworks commonly agreed upon by means of ontologies. However, users currently looking for ontologies in order to incorporate them into their systems, just use their experience and intuition. To improve the selection of ontologies, this chapter describes the ONTOMETRIC method which allows the users to measure the suitability of existing ontologies, regarding the requirements of their necessities.

A classification of methods and tools for the evaluation of ontologies for industrial practice is provided. It concerns methods and tools to:
Ontological evaluation and validation
2010
In the last few years, the Semantic Web gained scientific acceptance as the means of sharing knowledge in different domains, and the cornerstone of the Semantic Web is ontologies. Currently, users trying to incorporate ontologies in their applications have to rely on their experience to try to find a suitable ontology for their applications. Methods for evaluating ontology quality and validity, ontology characterization and ranking have been developed for that purpose.
Semantic Web, 2007
Recent years have seen rapid progress in the development of ontologies as semantic models intended to capture and represent aspects of the real world. There is, however, great variation in the quality of ontologies. If ontologies are to become progressively better in the future, more rigorously developed, and more appropriately compared, then a systematic discipline of ontology evaluation must be created to ensure quality of content and methodology. Systematic methods for ontology evaluation will take into account representation of individual ontologies, performance (in terms of accuracy, domain coverage and the efficiency and quality of automated reasoning using the ontologies) on tasks for which the ontology is designed and used, degree of alignment with other ontologies and their compatibility with automated reasoning. A sound and systematic approach to ontology evaluation is required to transform ontology engineering into a true scientific and engineering discipline. This chapter discusses issues and problems in ontology evaluation, describes some current strategies, and suggests some approaches that might be useful in the future.

Ontology evaluation is the task of measuring the quality of an ontology. It enables us to answer the following main question: How to assess the quality of an ontology for the Web? In this thesis a theoretical framework and several methods breathing life into the framework are presented. The application to the above scenarios is explored, and the theoretical foundations are thoroughly grounded in the practical usage of the emerging Semantic Web.
Evaluation of Ontologies and Ontology-based tools
Watson is a gateway to the Semantic Web: it collects, analyzes and gives access to ontologies and semantic data available online with the objective of supporting their dynamic exploitation by semantic applications. We report on the analysis of 25 500 ontologies and semantic documents collected by Watson, giving an account about the way semantic technologies are used to publish knowledge on the Web, about the characteristics of the published knowledge, and about the networked aspects of the Semantic Web. Our main conclusions are 1-that the Semantic Web is characterized by a large number of small, lightweight ontologies and a small number of large-scale, heavyweight ontologies, and 2-that important efforts still need to be spent on improving the published ontologies (coverage of different topic domains, connectedness of the semantic data, etc.) and the tools that produce and manipulate them.
A SURVEY OF ONTOLOGY EVALUATION TECHNIQUES
An ontology is an explicit formal conceptualization of some domain of interest. Ontologies are increasingly used in various fields such as knowledge management, information extraction, and the semantic web. Ontology evaluation is the problem of assessing a given ontology from the point of view of a particular criterion of application, typically in order to determine which of several ontologies would best suit a particular purpose. This paper presents a survey of the state of the art in ontology evaluation.
Redefinition and Statistical Analysis of Measures for Evaluating the Quality of Ontologies
2015
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.
