  1. Drivers and Impacts of ICT Adoption on Transport and Logistics Services. An European Perspective.

    Hidalgo Nuchera, Antonio; López Rodríguez, Vicente; Albors Garrigós, José
    The availability of high quality transport and logistics services (TLS) is of paramount importance for growth and competitiveness of an economy. The objective of this paper is to describe how companies in this industry use ICT for conducting business and to assess the impact of this development for firms and for the industry as a whole. Using the Structure-Conduct-Performance (SCP) model and the bi-directional relationships of its elements, the paper identifies the links between ICT adoption and market structure, innovation dynamics and firm performance. A set of recommendations on how to further improve the actual scenario of e-business in the...

  2. Building Ontology Networks: How to Obtain a Particular Ontology Network Life Cycle?

    Suárez-Figueroa, Mari Carmen; Gómez-Pérez, A.
    To build an ontology, ontology developers should devise first a concrete plan for the ontology development, that is, they should establish the ontology life cycle. To do this, ontology developers should answer two key questions: a) which ontology life cycle model is the most appropriate for their ontology project? and b) which particular activities should be carried out in their ontology life cycle? In this paper we present a set of guidelines to help ontology developers and also naïve users answer such questions.

  3. Selecting and Customizing a Mereology Ontology for its Reuse in a Pharmaceutical Product Ontology

    Fernández-López, M.; Gómez-Pérez, A.; Suárez-Figueroa, Mari Carmen
    This paper presents our experience in reusing mereology ontologies in a Pharmaceutical Product ontology, an ontology built by the EU NeOn project. It shows a set of mereology ontologies implemented in different machine interpretable languages and analyzes them according to the different types of mereology identified by Varzi. Then, it describes the specifications of mereology modeling necessities for Pharmaceutical Product. Finally, it presents the ontology which fits best with the specifications. One of the results of this work is a procedure to reuse general (also called common) ontologies.

  4. Providing Multilinguality to Ontologies: An Overview

    Aguado de Cea, G.; Montiel-Ponsoda, Elena
    Ontologies play a decisive role in the development of the Semantic Web, since they are able to model the knowledge of a specific domain in a machine readable way. However, the need to provide multilinguality to ontologies poses new challenges in the Ontology Engineering research. In this paper we attempt to offer an overview of available strategies for the localizing process of lexical resources and ontologies. Detailed steps in the localizing process of the multilingual lexicon EuroWordNet, the multilingual ontology GENOMA-KB, and the ontology translation software LabelTranslator are presented with the aim of illustrating three different localization approaches, their main...

  5. Evaluation of RDF(S) and DAML+OIL Import/Export Services within Ontology Platforms

    Gómez-Pérez, A.; Suárez-Figueroa, Mari Carmen
    Both ontology content and ontology building tools evaluations play an important role before using ontologies in Semantic Web applications. In this paper we try to assess ontology evaluation functionalities of the following ontology platforms: OilEd, OntoEdit, Protégé-2000, and WebODE. The goal of this paper is to analyze whether such ontology platforms prevent the ontologist from making knowledge representation mistakes in concept taxonomies during RDF(S) and DAML+OIL ontology import, during ontology building and during ontology export to RDF(S) and DAML+OIL. Our study reveals that most of these ontology platforms only detect a few mistakes in concept taxonomies when importing RDF(S) and DAML+OIL ontologies. It also reveals that most of these ontology...

  6. Towards a Catalog of OWL-based Ontology Design Patterns

    Gangemi, A.; Gómez-Pérez, A.; Presutti, V.; Suárez-Figueroa, Mari Carmen

  7. Towards a Glossary of Activities in the Ontology Engineering Field

    Suárez-Figueroa, Mari Carmen; Gómez-Pérez, A.
    The Semantic Web of the future will be characterized by using a very large number of ontologies embedded in ontology networks. It is important to provide strong methodological support for collaborative and context-sensitive development of networks of ontologies. This methodological support includes the identification and definition of which activities should be carried out when ontology networks are collaboratively built. In this paper we present the consensus reaching process followed within the NeOn consortium for the identification and definition of the activities involved in the ontology network development process. The consensus reaching process here presented produces as a result the NeOn Glossary of Activities. This work...

  8. First Attempt towards a Standard Glossary of Ontology Engineering Terminology

    Suárez-Figueroa, Mari Carmen; Gómez-Pérez, A.
    In this paper we present the consensus reaching process followed within the NeOn consortium for the identification and definition of the activities involved in the ontology network development process. This work was conceived due to the lack of standardization in the Ontology Engineering terminology, which clearly contrasts with the Software Engineering field that boasts the IEEE Standard Glossary of Software Engineering Terminology. The paper also includes the NeOn Glossary of Activities, which is the result of the consensus reaching process here explained. Our future aim is to standardize the NeOn Glossary of Activities.

  9. Benefits of Ontologies to Multilingual Needs

    Aguado de Cea, G.; Montiel-Ponsoda, Elena
    The way in which multilingual information is organized and presented, accounts for its usefulness or adequacy for a specific purpose. As globalization becomes more pervasive, people all over the world need to make use of information in different languages in their everyday work. Bilingual or multilingual dictionaries have been, and still are, relevant resources for facing up multilingual issues. However, the multilingual information collected in dictionaries remains insufficient for those people who need to gain a general view of a specific parcel of knowledge in two or more languages. In LSP (Language for Specific Purposes) this issue becomes even more...

  10. LexOMV: an OMV extension to capture multilinguality

    Montiel-Ponsoda, Elena; Aguado de Cea, G.; Suárez-Figueroa, Mari Carmen; Palma, R.; Peters, W.; Gómez-Pérez, A.
    In this paper we aim at proposing metadata for expressing information about multilingual data in ontologies. Nowadays, and thanks to ontology metadata standards as the Ontology Metadata Vocabulary (OMV), ontology developers can have an effective access to all available ontological resources in the web. However, this metadata does not offer information about the linguistic properties of the resource. Our proposal comes to solve this problem by adding an extension to the current OMV that documents about the linguistic or multilingual data contained in the ontology.

  11. Helping Naive Users to Reuse Ontology Design Patterns

    Montiel-Ponsoda, Elena; Aguado de Cea, G.; Gómez-Pérez, A.; Suárez-Figueroa, Mari Carmen
    The decisive launching of the Semantic Web depends on two key factors: the design of sound methodologies for guiding users in the reuse of available knowledge resources that speed up the ontology development, and the suitability of those methodologies for an average user. In this paper we propose a method for the reuse of ontology design patterns aimed at users with little expertise in ontology development, i.e. naive users. The method workflow is explained in the light of some examples of reuse of logical ontology design patterns: the SubClassOf relation, Exhaustive Classes and Disjoint Classes patterns.

  12. Using Natural Language Patterns for the Development of Ontologies

    Montiel-Ponsoda, Elena; Aguado de Cea, G.
    The combination of certain linguistic units that recurrently appear in text genres has attracted the attention of many researchers in several domains, as they can provide valuable information about different types of relations. In this paper, the focus will be on some of these combinatory units, referred to as Lexico-Syntactic Patterns (LSPs) that provide information about conceptual relations. The aim of this research is to detect recurrent patterns that express some of the most common conceptual relations present in ontologies. The purpose of this paper is to present the different strategies we have followed to identify LSPs which correspond to some of the main ontological relations, as...

  13. Modelling Multilinguality in Ontologies

    Montiel-Ponsoda, Elena; Aguado de Cea, G.; Gómez-Pérez, A.; Peters, W.
    an impending need for institutions worldwide with valuable linguistic resources in different natural languages. Since most ontologies are developed in one language, obtaining multilingual ontologies implies to localize or adapt them to a concrete language and culture community. As the adaptation of the ontology conceptualization demands considerable efforts, we propose to modify the ontology terminological layer, and provide a model called Linguistic Information Repository (LIR) that associated to the ontology meta-model allows terminological layer localization.

  14. Natural Language-based Approach for Helping in the Reuse of Ontology Design Patterns

    Aguado de Cea, G.; Gómez-Pérez, A.; Montiel-Ponsoda, Elena; Suárez-Figueroa, Mari Carmen
    Experiments in the reuse of Ontology Design Patterns (ODPs) have revealed that users with different levels of expertise in ontology modelling face difficulties when reusing ODPs. With the aim of tackling this problem we propose a method and a tool for supporting a semi-automatic reuse of ODPs that takes as input formulations in natural language (NL) of the domain aspect to be modelled, and obtains as output a set of ODPs for solving the initial ontological needs. The correspondence between ODPs and NL formulations is done through Lexico-Syntactic Patterns, linguistic constructs that convey the semantic relations present in ODPs, and which constitute the main contribution of this paper. The...

  15. When Phraseology and Ontologies Meet

    Aguado de Cea, G.; Montiel-Ponsoda, Elena
    In the field of Languages for Specific Purposes, phraseology plays a central role since its mastering is crucial for the different users that deal with specialized languages, from professionals of a domain to linguist experts (terminologists, translators, communication mediators, etc.). According to Aguado de Cea (2007), phraseology can be defined as: “the linguistic discipline that deals with the combination of words”, (…), or “the set of phraseological units or phrasemes” of a certain specialized language. In any case, phrasemes or lexical combinations are not only necessary for an adequate specialized communication, but they are also fundamental in the understanding of a certain domain of knowledge, together...

  16. SEEMP: Meaningful Service-based Collaboration Among Labour Market Actors

    Della Valle, E.; Cerizza, D.; Celino, I.; Estublier, J.; Vega, G.; Kerrigan, M.; Ramírez, J.; Villazón-Terrazas, B.; Guarrera, P.; Zhao, G.; Monteleone, G.
    SEEMP is an European Project that promotes increased partnership between labour market actors and the development of closer relations between private and public employment services, making optimal use of the various actors’ specific characteristics, thus providing job-seekers and employers with better services”. The need for such a flexible collaboration gives rise to the issue of interoperability in both data exchange and share of services. SEEMP proposes a solution that relies on the concepts of services and semantics in order to provide a meaningful service-based collaboration among labour market actors.

  17. SEEMP: A Semantic Interoperability Infrastructure for e-government services in the employment sector

    Della Valle, E.; Cerizza, D.; Celino, I.; Estublier, J.; Vega, G.; Kerrigan, M.; Ramírez, J.; Villazón-Terrazas, B.; Guarrera, P.; Zhao, G.; Monteleone, G.
    This paper presents SEEMP, a marketplace to coordinate and integrate public and private employment services (ESs) around the EU Member States. The need for flexible collaboration in the marketplace gives rise to the issue of interoperability in both data exchange and share of services. SEEMP proposes a mixed approach that relies on the concepts of services and semantics. SEEMP approach combines Software Engineering and Semantic Web methodologies/tools in an infrastructure that allows for a meaningful service-based communication among ESs.

  18. An Ontology for Modelling Human Resources Management based on Standards

    Gómez-Pérez, A.; Ramírez, J.; Villazón-Terrazas, B.
    Employment Services (ES) are becoming more and more important for Public Administrations where their social implications on sustainability, workforce mobility and equal opportunities play a fundamental strategic importance for any central or local Government. The EU SEEMP (Single European Employment Market-Place) project aims at improving facilitate workers mobility in Europe. Ontologies are used to model descriptions of job offers and curricula; and for facilitating the process of exchanging job offer data and CV data between ES. In this paper we present the methodological approach we followed for reusing existing human resources management standards in the SEEMP project, in order to build a common “language” called Reference Ontology.

  19. EgoIR: ontology-based information retrieval intended for eGovernment

    Ortiz-Rodriguez, F.; Palma, R.; Villazón-Terrazas, B.
    The eGovernment is a field of applications for the Semantic Web. The eGovernment also is becoming an important research area and faces considerable challenges to achieve interoperability because of the semantic differences of interpretation, complexity and width of scope. It is however an open question how to apply these techniques fruitfully in the eGovernment domain. This paper addresses the importance of providing a semantic application that, within the eGovernment domain, is capable of dealing with the issue of the retrieval of government documentation in a timely and accurate way. In this paper, we present an approach ontology-based for retrieving government information.

  20. Towntology & hydrOntology: Relationship between Urban and Hydrographic Features in the Geographic Information Domain

    Vilches-Blázquez, LM.; Bernabe Poveda, Miguel Angel; Suárez-Figueroa, Mari Carmen; Gómez-Pérez, A.; Rodríguez Pascual, AF.
    This article describes the relationship between Urban Civil Engineering and other domains, specifically the hydrographic domain. The process of building HydrOntology and the portion of the model relating to urban features are described. This ontology emerges with the intent of settling as a framework in the GI domain, very closely interrelating to Towntology.
