The Rhizomer platform is a Content Management System (CMS) based on a Resource Oriented Approach (RESTful) and Semantic Web technologies. It achieves a great level of flexibility and provides sophisticated content management services. All content is described using semantic metadata semi-automatically extracted from multimedia content, which enriches the(More)
Semantic Web applications take off is being slower than expected, at least with respect to " real-world " applications and users. One of the main reasons for this lack of adoption is that most Semantic Web user interfaces are still immature from the usability and accessibility points of view. This is due to the novelty of these technologies, but this also(More)
In order to make Semantic Web tools more appealing to lay-users, a key factor is their Quality in Use, the quality of the user experience when interacting with them. To assess and motivate the improvement of the quality in use, it is necessary to have a quality model that guides its evaluation and facilitates comparability. The proposal is based on the(More)
In order to make a Semantic Web dataset more usable to a wider range of users, specially Linked Data ones, Rhizomer constitutes a tool for data publishing in the web that in addition to common data browsing mechanisms based on HTML rendering, provides a set of components that facilitate awareness of the dataset at hand borrowed from Information(More)
Quality Management has become a strategic issue for organisations and very valuable to produce quality software. However, Quality Management Systems (QMS) are not easy to implement and maintain. Our experience shows the benefits of developing a QMS by first formalising it using Semantic Web ontologies and then putting them into practice through a semantic(More)
Semantic Web applications tests show that their usability is seriously compromised. This motivates the exploration of alternative interaction paradigms, different from the "traditional" Web or desktop applications ones. The Rhizomer platform is based on the object-action interaction paradigm, which is better suited for heterogeneous resource spaces such as(More)
Thanks to Open Data initiatives the amount of data available on the Web is rapidly increasing. Unfortunately, most of these initiatives only publish raw tabular data, what makes its analysis and reuse very difficult. Linked Data principles allow for a more sophisticated approach by making explicit both the structure and semantics of the data. However, from(More)
LINNEO + is the implementation of a classiica-tion methodology for concept acquisition from non-classiied examples in ill-structured domains. In order to achieve this aim LINNEO + uses incremental conceptual clustering and domain knowledge expressed by means of expert's rules. The nal target is to build knowledge bases or libraries of cases after expert's(More)
Rhizomer addresses the exploration of semantic data by lay users by applying the data analysis mantra of overview, zoom and filter. These interaction patterns are implemented using information architecture components users are already familiar with but that are automatically generated from data and ontologies. This approach makes it possible to obtain an(More)
AbstrAct Newspapers in the digitalisation and Internet era are evolving from mono-channel and static communication mediums to highly dynamic and multi-channel ones, where the different channels converge into a unified news editorial office. Advanced comput-erised support is needed in order to cope with the requirements arising from convergent multimedia(More)
