“…Topic maps establish an associative network between subjects, which represent information objects, and provide navigation paradigms that allow them to be searched. By applying topic maps to large sets of heterogeneous information repositories, reusable and structured semantic link networks are created on a level above those resources (Rath & Pepper, 1999). The key concepts of topic maps are topics, which represent real-world subjects, occurrences of topics, and relationships between topics (topic associations).…”

For a company to be consistently oriented toward its customers and their processes, it needs to customize its intra-corporate processes and systems. Customer process-oriented portals that integrate companies' systems and provide transparent access to information objects stored in these systems seem to offer a solution. However, one key problem is finding relevant information objects in systems that are not only growing, but also being disseminated. There is the additional challenge of making knowledge available at the right time and the right place. Companies' competitive advantage is rooted in this knowledge advantage as well as in the capability to transform this superior knowledge into market-driven business processes. The research questions addressed in this article are how the value of information objects is affected by the context in which it is considered, and how associated contexts can be uncovered for given situations. We introduce a continuum of context explication comprised of the relationships between data, information objects, and knowledge, and their contexts, according to their degree and ease of context explication. The extremes of the continuum would therefore be data with no context to explicate and knowledge with rich, person-specific context. We conclude that discovering implicit meanings and expressing those meanings explicitly increases the potential value of information objects. In addition, we evaluate the full-text search, attributebased search, and topic maps as approaches for knowledge discovery through customer processoriented portals as well as providing patterns that indicate when to apply which approach. Two small case studies of knowledge discovery through such portals are presented. We conclude with suggestions for future research based on our final deductions in respect of the study.

“…Esta norma internacional aporta los signos estandarizados necesarios para representar la información de los diferentes recursos desde la definición de los conceptos y las relaciones que existen entre ellos 10 . Así, un conjunto de uno o más documentos que utiliza la notación definida por este estándar origina un mapa conceptual o temático (topic map).…”

RESUMENEl sustantivo crecimiento del número de tesauros no ha servido para responder a la necesidad de trabajar en entornos multidisciplinares. Para responder a esta situación, se fomentó, en un primer momento, la fusión de tesauros con objeto de adaptar los preexistentes a las necesidades planteadas por los nuevos dominios. Más tarde, en el afán de atender precisamente a un mundo de información cambiante y en crecimiento, se empezó a trabajar en los mapas conceptuales de navegación. Hasta desembocar en los Topic maps surgidos de la necesidad de fusionar índices para incorporar así la utilidad de los hiperenlaces. Su éxito se plasmó en la norma ISO/ICE 13250:1999, que motivó la hipótesis de su uso en la elaboración de tesauros, proceso en el que se manifestaron las contradicciones entre ambos sistemas. Por lo que se analizan los elementos conceptuales esenciales en la arquitectura de los topics maps para hallar su correlato en los tesauros. Este estudio comparativo permite señalar como límites de los topics maps, su indefinición conceptual, sus innumerables relaciones y su ambigüedad, lo que no oculta sus ventajas como una mayor riqueza semántica, la consecución de un nuevo marco conceptual para dominios fusionados, las asociaciones determinadas por verbos y la capacidad de organizar recursos informativos de distinto tipo.

INTRODUCCIÓNEl sustantivo crecimiento del número de tesauros no ha servido para responder a la necesidad de trabajar en entornos multidisciplinares, por lo que en un primer momento se fusionaron tesauros con objeto de adaptar los preexistentes a las necesidades planteadas por los nuevos dominios 2 . Más tarde, en el afán de atender precisamente a un mundo de información cambiante y en crecimiento, se empezó a trabajar en los conocidos mapas conceptuales de navegación. El estudio de los mapas temáticos se originó en la necesidad de crear índices en torno a algún concepto o materia.

Abstract. Topic Maps are a standardized modelling approach for the semantic annotation and description of WWW resources. They enable an improved search and navigational access on information objects stored in semi-structured information spaces like the WWW. However, the according standards ISO 13250 and XTM (XML Topic Maps) lack formal semantics, several questions concerning e.g. subclassing, inheritance or merging of topics are left open. The proposed TMUML meta model, directly derived from the well known UML meta model, is a meta model for Topic Maps which enables semantic constraints to be formulated in OCL (object constraint language) in order to answer such open questions and overcome possible inconsistencies in Topic Map repositories. We will examine the XTM merging conditions and show, in several examples, how the TMUML meta model enables semantic constraints for Topic Map merging to be formulated in OCL. Finally, we will show how the TM validation process, i.e., checking if a Topic Map is well formed, includes our merging conditions.
