Evaluating Query and Storage Strategies for RDF Archives

Javier D. Fernández, Jürgen Umbrich, Axel Polleres, Magnus Knuth
2016 Proceedings of the 12th International Conference on Semantic Systems - SEMANTiCS 2016  
As novel archiving systems are starting to address this challenge, foundations/standards for benchmarking RDF archives are needed to evaluate its storage space efficiency and the performance of different  ...  RDF data.  ...  EvoGen [27] is a recent suite that extends the traditional LUBM benchmark [19] to provide a dataset generator for versioned RDF data.  ...

Evaluating Geospatial RDF stores Using the Benchmark Geographica 2

Theofilos Ioannidis, George Garbis, Kostis Kyzirakos, Konstantina Bereta, Manolis Koubarakis
2020 Zenodo  
Alongside with the ever-increasing size of linked geospatial data that semantic stores need to handle, all the above provided our group the motivation to improve our single node systems benchmark Geographica  ...  A parallel process with the above was that RDF frameworks evolved in an interesting way by presenting a more mature set of geospatial features, such as GeoSPARQL support and including the latest indexing  ...  EvoGen [24] , a LUBM derivative, is a synthetic benchmark for evolving RDF.  ...

In the first direction (chapters 2 and 3), we study the problem of representing, storing and querying evolving RDF data.  ...  To this end, we focus in three directions, namely (i) RDF data evolution, (ii) storage, indexing and query optimization in RDF/SPARQL engines, and (iii) efficient and scalable information retrieval from  ...  Ioannis Anagnostopoulos, for guiding me, completely trusting in me and granting the required autonomy to pursue the directions studied in this thesis. Furthermore, I would like to thank Dr.  ...
