Joining linked open data cubes

Abstract

The subject of this thesis is “Joining Linked Open Data Cubes” and deals with the investigation of applying traditional join types found in relational algebra to Linked Data Cubes. The investigation is based on a review of the multidimensional structures, of Linked Data and the join types defined in relational algebra. All the details of these three areas are used to conceptualize the way a join can happen between two Linked Data Cubes. The concepts that are established to achieve the join of Cubes are proven by implementing a program and using it against a dataset with Linked Open Data Cubes. The results of the program execution are analyzed revealing some interesting findings.
