Here is our weekly catch-up, summarising activities discussed last week. Feel free to reach out to us if you have a topic you would like us to cover in more detail
For week ending Friday, 2019-09-13
Football/Soccer Transfers Graph Analysis. Here is an aid for comparing Graph Analytics approaches using the same source data in Neo4j (using Cypher) and in our Virtuoso (using SPARQL with Business Intelligence extension, i.e., SPARQL-BI).
How to Rebuild Virtuoso Full Text Index
New version 8.0 ODBC Drivers (Connectors) for PostgreSQL immediately available for Linux, Windows, macOS. Key features: Unicode UTF-16 & UTF-32 support; Usable via iODBC or unixODBC runtime (outside Windows).
Our new high-performance Driver/Connector supports the PostgreSQL 3.0 wire protocol and works smoothly with instances deployed via Azure or the AWS clouds.

Entity Resolution using Semantic Web. For example, when two entities have been explicitly designated as equivalent via an owl:sameAs relationship type (relation).
The LODCloud is a progressively expanding Knowledge Graph, driven by the power of Linked Data. Basically, a Digital Super Highway for Data, Information, and Knowledge, where a single Hyperlink is the entry point.
The LODCloud Knowledge Graph holds info about lots of organizations that are classified using terms from FOAF and SchemaOrg ontologies, disparately. Thus, how do you reconcile?
So you have 77 pages of information when the magic of Reasoning and Inference isn’t applied (i.e., is disabled), and when applied it jumps to 5,806 pages
Important Digital Transformation goals that you can’t achieve without a Knowledge Graph that manifests as a Semantic Web.
Is the LODCloud Live? Of course! Every Hyperlink in this cloud has the dual capability of denotation & connotation; i.e., when you click on a link it resolves to a document that describes its referent (whatever the link identifies).

If SPARQL is so bad, and GSQL is so good, producing a live demonstration of that claim should be trivial. We are still looking for a Graph Database replica of a single node in the LODCloud!
“LODCloud is the largest Knowledge Graph on the Web, by far,” might sound audacious, but in reality it’s a pretty modest claim.
The schema:mentions property has a list of values generated from NLP services that leverage the LODCloud as part of their basic operations. Net effect, a Small Data pattern for progressively creating a personalized Knowledge Graph. (You own the Analytics too!)
Thanks to SPARQL being an extension of HTTP, you can alter a query result page link such that it resolves back to a query editor (if our Virtuoso is the back-end). Even better, tweak and publish variations of original queries, etc.
