OBJECTIVE Development of a Semantic Web technology based system for the formalization of the gross description. METHOD A system is developed using the Java-2 platform. It is based on a light-weight version of the Galen top level ontology. Web technologies like XML, SAX en DOM have been used. RESULT Three system components have been developed to support(More)
There is a growing interest on how we represent and share tagging data for the purpose of collaborative tagging systems. Conventional tags are not naturally suited for collaborative processes. Being free-text keywords, they are exposed to linguistic variations like case (upper vs lower), grammatical number (singular vs. plural) as well as human typing(More)
Clinical Practice Guidelines (CPGs) play an important role in improving the quality of care and patient outcomes. Although several machine-readable representations of practice guidelines implemented with semantic web technologies have been presented, there is no implementation to represent uncertainty with respect to activity graphs in clinical practice(More)
Tagging has proven to be a successful and efficient way for creating metadata through a human collective intelligence. It can be considered not only an application of individuals for expressing one's interests , but also as a starting point for leveraging social connections through collaborative user participations. A number of users have contributed to tag(More)
In this paper we describe the SCOT Exporter and its algorithms to create instance data based on the SCOT (Social Semantic Cloud of Tags) ontology for sharing and reusing tag data. The algorithms use tag frequencies and co-occurrence relations to represent statistical information via the SCOT ontology. We give an overview of the Exporter and the algorithms,(More)
In this paper we give an overview of the int.ere.st for a social tagging, bookmarking, and sharing service. It is based on the SCOT ontology. The SCOT ontology can represent the structure and semantics for social tagging data and provide methods for sharing and reusing them. We describe how it enables users to participate in a semantic social tagging from(More)
In this paper, we present our development of a document management and retrieval tool, which is named <i>Ontalk</i>. Our system provides a semi-automatic metadata generator and an ontology-based search engine for electronic documents. <i>Ontalk</i> can create or import various ontologies in RDFS or OWL for describing the metadata. Our system that is built(More)
