Conforme se incrementan los recursos web se evidencia la falta de sistemas de organización del conocimiento, con el consiguiente impacto en la interoperabilidad de recursos. Los sistemas de organización del conocimiento son por definición herramientas complicadas y costosas, tanto en su creación como en su gestión. La reutilización de estructuras organizativas similares es un elemento necesario en este contexto. Se analizan experiencias de reutilización de sistemas de organización del conocimiento y se señala como los nuevos estándares están incidiendo en este aspecto.

It extends the approach developed by the FUNSIEC project through a set of propositions intended to increase the quantity and the quality of semantic mappings. The evaluation of the semantic mappings targets two directions, i.e. to assess the quality of the mappings using fuzzy logic techniques and to calculate how much a specific mapping is appropriate to a user context. Conclusions and further work are also discussed here.

This paper presents a three-step approach to enhance interoperability between heterogeneous semantic resources. Firstly, we construct homogeneous representations of these resources in a pivot format, namely OWL DL, with respect to the semantics expressed by the original representation languages. Secondly, mappings are established between concepts of these standardised resources and stored in a so-called articulation ontology. Thirdly, an approach for ranking those mappings
is suggested in order to best fit users’ needs. This approach is currently being implemented in the Semantic Resources “Interoperabilisation” and Linking System (SRILS). The mapping results as well as the work to be done are discussed.

El análisis conceptual de mapeados y alineamientos de ontologías ha permitido diseñar un sistema para consensuar semántica de vocabularios de metadatos mediante una ontología de alto nivel. Para la definición del método se han seleccionado 6 vocabularios de metadatos y se han realizado pruebas de alineamiento manual y correspondencia conceptual con la ontología de referencia. PROTON ha sido la ontología de referencia seleccionada por adaptarse al dominio, extensibilidad, adecuación al sistema de recuperación y disponibilidad. El resultado del proceso es la formalización de los vocabularios y el enriquecimiento de la semántica. Estas características favorecen el uso y el funcionamiento de este tipo de recursos. La solución está basada en un sistema de formalización web basado en niveles semánticos, para evitar modificar el recurso original y facilitar la extensibilidad al reducir las dependencias entre los elementos. La principal aportación de este estudio es un método para la formalización y desambiguación de vocabularios de metadatos, donde pueden convivir e interoperar todos los elementos de los vocabularios sin tener que reetiquetar o desestimar por posibles usos minoritarios u obsolescencia de los vocabularios. Además, esta propuesta permite y facilita la reutilización de los vocabularios de metadatos, la interoperabilidad y recuperación conceptual.

Interoperability has been a basic requirement for the modern information systems environment for over two decades. How have key requirements for interoperability changed over that time? How can we understand the full scope of interoperability
issues? What has shaped research on information system interoperability? What key progress has been made? This chapter provides some of the answers to these questions. In particular, it looks at different levels of information system
interoperability, while reviewing the changing focus of interoperability research themes, past achievements and new challenges in the emerging global information infrastructure (GII). It divides the research into three generations, and discusses some of achievements of the past. Finally, as we move from managing data to information, and in future knowledge, the need for achieving semantic interoperability is
discussed and key components of solutions are introduced.

Os museus da CPLP têm a língua portuguesa como um dos seus mais importantes traços identitários. Contudo, falarmos a mesma língua não chega para que se construa uma linguagem comum. A construção de uma linguagem comum aos museus da CPLP necessita de instrumentos de normalização e controle terminológico, bem como da definição semântica de conceitos e da normalização de procedimentos na sua utilização.
As tecnologias da informação apresentam-se como um poderoso auxiliar nesta tarefa e são apresentados dois exemplos em Portugal em que a sua utilização, bem como a realização de programas de formação orientados para o seu uso, contribuíram para a criação de sistemas interoperáveis e de redes de cooperação e partilha de recursos.
Discute-se a oportunidade e o desafio que pode constituir a criação de uma rede de profissionais no âmbito da CPLP, entendida como espaço de universalização de normas e conceitos nos museus de língua portuguesa.

A vast amount of such information has been created by memory institutions in the last decades using different standard or ad hoc schemas, and a main challenge is to make this legacy data accessible as reusable semantic data. On one hand, this is a syntactic problem that can be solved by transforming to formats that are compatible with the tools and services used for semantic aware services. On the other hand, this is a semantic problem. Simply transforming from one format to another does not automatically enable semantic interoperability and legacy data often needs to be reinterpreted as well as transformed. The conceptual model in the Functional Requirements for Bibliographic Records, initially developed as a conceptual framework for library standards and systems, is a major step towards a shared semantic model of the products of artistic and intellectual endeavor of mankind. The model is generally accepted as sufficiently generic to serve as a conceptual framework for a broad range of cultural heritage metadata. Unfortunately, the existing large body of legacy data makes a transition to this model difficult. For instance, most bibliographic data is still only available in various MARC-based formats which is hard to render into reusable and meaningful semantic data. Making legacy bibliographic data accessible as semantic data is a complex problem that includes interpreting and transforming the information. In this article, we present our work on transforming and enhancing legacy bibliographic information into a representation where the structure and semantics of the FRBR model is explicit.
Comparing categories among geographic ontologies

An essential step towards their success is the ability to compare the categories involved. This paper introduces a systematic methodology for comparing categories met in geographic ontologies. The methodology explores/extracts semantic information provided by categories’ definitions. The first step towards this goal is the recognition of syntactic and lexical patterns in definitions, which help to identify (a) semantic properties such as purpose, location, cover, and (b) semantic relations such as hypernym, part of, has-parts, etc. At the second step, a similarity measure among categories is applied, in order to explore how (the) extracted properties and relations interrelate. This framework enables us to (a) better understand the impact of context in cross-ontology “mappings”, (b) evaluate the “quality” of definitions as to whether they respect mere ontological aspects (such as unambiguous taxonomies), and (c) deal more effectively with the problem of semantic translation among geographic ontologies.

Hitherto, the task of generating mappings between ontologies has focused on the intensional level of ontologies. The term intensional level herein, refers to the set of concepts that are included in an ontology. However, an ontology that has been created for a specific task or application needs to be populated with instances. These comprise the extensional level of an ontology. This particular level is generally neglected during the ontologies’ integration procedure. Thus, although methodologies of geographic ontologies integration, ranging from alignment to true integration, have, in the course of years, presented a solid ground for information exchange, little has been done in exploring the relationships between the data. In this context, this research strives to set a framework for extensional mappings between ontologies using Information Flow Theory by presenting a case study of interoperability between the thematic content of maps.
Textual representations and knowledge support-systems in research intensive networks.

To support the increased efficacy and efficiency of research intensive networks and their impact in the world, we claim there is a need to expand the context of knowledge systems associated with research intensive networks. This idea for us involves the development of a public knowledge imperative. We suggest that textual representations expressed as knowledge claims can no longer be hidden away from the eyes of public scrutiny when there are important matters of public interest either implicitly or explicitly at stake. The recent catastrophe in the Gulf of Mexico provides an example of how particular types of knowledge, for example, procedures associated with offshore oil rigs, can rise up to become of the highest public priority almost overnight. To neglect the potency of such knowledge through a lack of public scrutiny can have devastating consequences, as the whole world has found out.
In this chapter we set out to provide a rationale as to why we think a public knowledge imperative is so important. To give expression to this imperative, we think there is a need for a new type of institutional and regulatory framework to protect and enhance the role of public knowledge. We call this framework a public knowledge space. It is public by virtue of the fact that it relies on semantic technologies and web publishing principles. But more importantly, in order to understand the multiple functions of a public knowledge space, we suggest it is first necessary to develop a detailed ontology of knowledge itself. Our ontology outlined in this chapter is broadly based because we emphasise the value of experience and lifeworlds as much as we do the importance of rigorous critiquing and transparent review. By extension, our views are slightly orthogonal to prevailing perspectives of the semantic web.

A method to map heterogeneity between near but non-equivalent semantic attributes in multiple health data registries
Schuurman N., and A. Leszczynski, 2008. "A method to map heterogeneity between near but non-equivalent semantic attributes in multiple health data registries," Health Informatics Journal 14(1): 39-57
Health registries from multiple jurisdictions often include terms that are assumed to be semantically equivalent (e.g.... more Health registries from multiple jurisdictions often include terms that are assumed to be semantically equivalent (e.g. fetal death and stillbirth). Closer examination reveals that such attributes have near — but non-equivalent — semantics. Thus their degree of semantic heterogeneity is an important indicator of uncertainty associated with data integration between registries. We build an OWL-encoded ontology which formalizes the relationships between similar perinatal concepts found in different databases. We also introduce the concept of ontology-based metadata as a means of contextualizing such terms and linking context to the attribute data. This extended metadata are exported as XML from the health registries, and it — along with the OWL ontology — is interfaced via a web-based GUI accessible to health researchers. The GUI mapping serves as the basis for making ad hoc comparison and integration decisions. Uncertainty is addressed by precisely mapping semantic heterogeneity between fields.

In this paper, we discuss on the relevance and impact of the current ISU research to the semantic interoperability in general and propose an original architecture for im-plementation of the Semantic Interoperability Service Utilities (S-ISU). The proposed architecture is formalized by the S-ISU Ontology – a meta-model for the semantic interoperability of the Enterprise Information Systems. Its in-tended purpose is to be used as abstract model for design of the organizational and asset perspective of the systems interoperability in a virtual enterprise.
