چکیده
Data Cube is an effective technique for data mining. Because of the complex relationships among aggregation values of a data cube, designing an efficient method or tool to visualize the complex relationships becomes a challenging work in the data cube technique. Information visualization with computer graphics can help improving this process. Recently, we developed a Web-based interactive data cube visualization system that can be applied to visualize a single data cube or parallel data cubes conveniently on the Web. This paper presents the basic principle, structure and features of the system.

متن کاملAlignment Cubes: Towards Interactive Visual Exploration and Evaluation of Multiple Ontology Alignments
Ontology alignment is an area of active research where many algorithms and approaches are being developed. Their performance is usually evaluated by comparing the produced alignments to a reference alignment in terms of precision, recall and F-measure. These measures, however, only provide an overall assessment of the quality of the alignments, but do not reveal differences and commonalities be...

متن کاملManaging distributed statistical data in the semantic web
The RDF Data Cube Vocabulary is the W3C recommendation for publishing multidimensional statistical data in a semantic web format. A large and growing number of such data cubes is already available in the linked data cloud, but the data is distributed and isolated in many remote repositories. Having access to the data, applications can now be developed to explore and use it. To handle and correl...
