A-tree: Distributed indexing of multidimensional data for cloud computing environments

Papadopoulos, A.; Katsaros, D. (2011)

Efficient querying of huge volumes of multidimensional data stored in cloud computing systems has become a necessity, due to the widespread of cloud storage facilities. With clouds getting larger and available data growing ...

Computational methods and optimizations for containment and complementarity in web data cubes

Meimaris M., Papastefanatos G., Vassiliadis P., Anagnostopoulos I. (2018)

The increasing availability of diverse multidimensional data on the web has led to the creation and adoption of common vocabularies and practices that facilitate sharing, aggregating and reusing data from remote origins. ...

Efficient computation of containment and complementarity in RDF data cubes

Meimaris M., Papastefanatos G., Anagnostopoulos I., Vassiliadis P. (2016)

Multidimensional data are published in the web of data under common directives, such as the Resource Description Framework (RDF). The increasing volume and diversity of these data pose the challenge of finding relations ...

A New Topology-Preserving Distance Metric with Applications to Multi-dimensional Data Clustering

Delibasis K.K. (2019)

In many cases of high dimensional data analysis, data points may lie on manifolds of very complex shapes/geometries. Thus, the usual Euclidean distance may lead to suboptimal results when utilized in clustering or visualization ...
