Molecular sequence data have become the standard in modern day phylogenetics. In particular, several long-standing questions of mammalian evolutionary history have been recently resolved thanks to the use of molecular characters. Yet, most studies have focused on only a handful of standard markers. The availability of an ever increasing number of whole(More)
This paper presents the principles of ontology-supported and ontology-driven conceptual navigation. Conceptual navigation realizes the independence between resources and links to facilitate interoperability and reusability. An engine builds dynamic links, assembles resources under an argumentative scheme and allows optimization with a possible constraint,(More)
Ontologies are widely adopted in the biomedical domain to characterize various resources (e.g. diseases, drugs, scientific publications) with non-ambiguous meanings. By exploiting the structured knowledge that ontologies provide, a plethora of ad hoc and domain-specific semantic similarity measures have been defined over the last years. Nevertheless, some(More)
Social photos, which are taken during family events or parties, represent individuals or groups of people. We show in this paper how a Hasse diagram is an efficient visualization strategy for eliciting different groups and navigating through them. However, we do not limit this strategy to these traditional uses. Instead we show how it can also be used for(More)
Music is both a social and a personal experience. Our goal is to automatically compose music playlists that combine the personal expectations of the listener with the expertise of professional playlist composers (or DJs). This paper begins by introducing an environment in the form of a music landscape that can be used for indexing music, navigating through(More)
This paper presents an innovative integrated visual approach for indexing music and for automatically composing personalized playlists for radios or chain stores. To efficiently index hundreds of music titles by hand with artistic descriptors, the user only needs to drag and drop them onto a dynamic music landscape. To help the user we propose different(More)
