The Lothbrok approach for SPARQL Query Optimization over Decentralized Knowledge Graphs
Christian Aebeloe, Gabriela Montoya, Katja Hose
While the Web of Data in principle offers access to a wide range of interlinked data, the architecture of the Semantic Web today relies mostly on the data providers to maintain acc…
Star Pattern Fragments: Accessing Knowledge Graphs through Star Patterns
Christian Aebeloe, Ilkcan Keles, Gabriela Montoya +1
The Semantic Web offers access to a vast Web of interlinked information accessible via SPARQL endpoints. Such endpoints offer a well-defined interface to retrieve results for compl…
Querying Linked Data: An Experimental Evaluation of State-of-the-Art Interfaces
Gabriela Montoya, Ilkcan Keles, Katja Hose
The adoption of Semantic Web technologies, and in particular the Open Data initiative, has contributed to the steady growth of the number of datasets and triples accessible on the…
The Odyssey Approach for Optimizing Federated SPARQL Queries
Gabriela Montoya, Hala Skaf-Molli, Katja Hose
Answering queries over a federation of SPARQL endpoints requires combining data from more than one data source. Optimizing queries in such scenarios is particularly challenging not…
Efficient Query Processing for SPARQL Federations with Replicated Fragments
Gabriela Montoya, Hala Skaf-Molli, Pascal Molli +1
Low reliability and availability of public SPARQL endpoints prevent real-world applications from exploiting all the potential of these querying infras-tructures. Fragmenting data o…
Fedra: Query Processing for SPARQL Federations with Divergence
Gabriela Montoya, Hala Skaf-Molli, Pascal Molli +1
Data replication and deployment of local SPARQL endpoints improve scalability and availability of public SPARQL endpoints, making the consumption of Linked Data a reality. This sol…
