Semantic HMC for Big Data Analysis [article]

Thomas Hassan, Aurlie Bertaux, Nuno Silva
2014 arXiv   pre-print
Analyzing Big Data can help corporations to im-prove their efficiency.  ...  In this work we present a new vision to derive Value from Big Data using a Semantic Hierarchical Multi-label Classification called Semantic HMC based in a non-supervised Ontology learning process.  ...  SEMANTIC HMC PROCESS Our Semantic HMC process is generic for a large Variety of unstructured data items (e.g. text, images) and scalable for a large Volume of data.  ...

Semantic big data for tax assessment

Stefano Bortoli, Paolo Bouquet, Flavio Pompermaier, Andrea Molinari
2016 Proceedings of the International Workshop on Semantic Big Data - SBD '16  
Semantic Big Data is about the creation of new applications exploiting the richness and flexibility of declarative semantics combined with scalable and highly distributed data management systems.  ...  Further, we introduce the concept of Entiton as a flexible and efficient data model suitable for large scale data inference and analytic tasks.  ...  We believe that thanks to this combination of Semantic and Big Data technologies we are now walking the last mile for the creation of real world semantic applications.  ...

Knowledge cubes — A proposal for scalable and semantically-guided management of Big Data

Amgad Madkour, Walid G. Aref, Saleh Basalamah
2013 2013 IEEE International Conference on Big Data  
Knowledge cubes support the five pillars of Big Data also known as the five V's, namely Volume, Velocity, Veracity, Variety, and Value.  ...  In this paper, knowledge cubes are proposed as a semantically-guided data management architecture, where data management is influenced by the data semantics rather than by a predefined scheme.  ...  Discovery of Data Sources Each knowledge cube can have its own discovery mechanism for the list of Big Data sources relevant to its semantic aspects.  ...
