QuWeDa 2023 : 7th Workshop on Storing, Querying and Benchmarking Knowledge Graphs @ISWC2023

The constant growth of Knowledge Graphs (KGs) on the Web raises new challenges for querying and integrating massive amounts of data across multiple KGs. Such KGs are available through various interfaces, such as data dumps, Linked Data Platform, SPARQL endpoints and Triple Pattern Fragments. In addition, various sources produce streaming data. Efficiently querying these sources is of central importance for the scalability of Linked Data and Semantic Web technologies. To exploit the massive amount of data to its full potential, users should be able to query and combine this data easily and effectively.


This workshop at the International Semantic Web Conference 2023 (ISWC 2023) seeks original articles describing theoretical and practical methods and techniques for fostering, querying, and consuming the Data Web. Topics relevant to this workshop include -- but are not limited to -- the following:

Representing and Storing the Web of Data as Knowledge Graphs
Efficient representation
Indexing
Caching and replication
Storage techniques
Real-time data warehousing from Web data


Querying the Web of Data as Knowledge Graphs
