HowTos

• Solving Product Management Challenges via a Product Knowledge Graph

• How to build Data Analytics dashboards using @PowerBI that target any public or private Knowledge Graph via our Virtuoso and its high-performance and secure ODBC Driver.

• How to build @tableau reports using HTTP, ODBC, or JDBC connections to a Knowledge Graph, courtesy of our Virtuoso and its powerful Data Access Driver offerings.

• Here is how to install and configure AmazonEKS Kubernetes and deploy a Virtuoso Docker container within it.

• Demo re: how a Knowledge Graph is derived in virtual form by transforming data associated with Tables attached to Virtuoso via ODBC. The end product is a navigable Knowledge Graph comprising #LinkedData derived from the Northwind Database

• This is how the power of Identity enables recalibration of Privacy using Attribute-based Access Controls (ABAC), that scales to both the Internet and Web networks.

• If SPASQL is the answer, what is the question?

• Great example of what’s possible when applying the Data Access and Data Connectivity power of SPARQL to a COVID19 oriented Knowledge Graph.

• I’ll never stop being amazed by the power of Data. Here’s how its gathering provides historic perspective for future guidance re human enslavement.

• We’ve loaded this Linked Data to our LOD Cloud cache instance. Our VirtuosoRDBMS includes a uniquely scalable DBMS-hosted Faceted Browsing engine for Knowledge Graph exploration using the Follow-Your-Nose pattern

• There are quite a few Ontology developments associated with COVID19.
  Here’s a SPARQL query results page that provides an index of what’s made its way into the LODCloud Knowledge Graph via our URIBurner service.

• A nice HTTP URL or URI explainer By @DanielMiessler
  This doc also includes coherent use of schema:sameAs for Identity assertion that can be verified logically (e.g., using a SPARQL query).

• A Wikipedia doc now includes Linked Data that creates THE critical segue from plain text to a Knowledge Graph via RDF – using terms from the SchemaOrg vocabulary

• What is the Virtuoso Sponger Middleware Layer and why is it important?

• Some really cool Solid use-cases presented during this event. BBC – at 16:33 Natwest Bank: at 29:37

• OpenLink Structured Data Sniffer (@datasniff) has also found an Offers and Pricing Knowledge Graph embedded within the iPadAir “Buy” Page.

• As each of these pages from @apple is a Knowledge Graph in its own right, constructed using RDF statements, I can also issue SPARQL queries directly targeting these pages to obtain specific info.

• Courtesy of our @datasniff, I can see that @apple has RDF embedded in their HTML docs that describes the new Apple Watch using terms from SchemaOrg.

• If the answer is Virtuoso JDBC or ODBC Drivers, what is the question?

• Our VirtuosoRDBMS anchors the LOD Cloud Knowledge Graph via DBpedia and a majority of nodes in said cloud. That said, how big is an actual binary?
  Sizes in Megabytes:
  macOS 19.6
  Linux 54.0
  Windows 18.2

• Covid-on-the-Web: Knowledge Graph and Services to Advance COVID-19 Research" a dataset comprising two main knowledge graphs, including named entities linked to @DBpedia, @Wikidata and other @BioPortal vocabularies.

• You take control over you Identity (and by effect Privacy) by getting yourself a WebID derived from a Profile Knowledge Graph. Increasingly, this can start from Profile pages created using @carrd, @glitch, @github etc…

• Might help you understand why the domain and range of a relationship type (relation) is important etc.
