Abstract HCI systems are often equipped with gestural interfaces drawing on a predefined set of admitted gestures. We provide an assessment of the fitness of such gesture vocabularies in terms of their learnability and naturalness. This is done by example of rivaling gesture vocabularies of the museum information system WikiNect. In this way, we do not only provide a procedure for evaluating ge...

One of the major barriers to the deployment of Linked Data is the difficulty that data publishers have in determining which vocabularies to use to describe the semantics of data. This systematic report describes Linked Open Vocabularies (LOV), a high-quality catalogue of reusable vocabularies for the description of data on the Web. The LOV initiative gathers and makes visible indicators such as...

Recent work analyzing changes on the Linked Open Data (LOD) cloud on fine-grained weekly snapshots shows that vocabularies published on the cloud are highly static. While this result is quite expected, there is another kind of schematic information that can be observed on the LOD cloud: the use of the vocabularies in the cloud. With use, we mean the combinations of sets of properties and sets o...

During the past few years, many consumer-oriented vocabularies have been developed to reflect the multitude of ways consumers express health topics, in order to help lay users access health information and manage their personal healthcare data. To address problems such as interoperability, ambiguity, and heterogeneity of medical information, the lay expressions from consumer vocabularies need t...

The Linked Data standard — which is based on the publication of data in the Web as RDF triples — is gaining increasing attention as a way to promote open data interoperability. The publication of data originally stored in relational databases as RDF is known as the RDB-to-RDF approach. The first step in this process requires the mapping of database concepts to RDF vocabularies, used as the base...
