Boom!

The OpenLink Software #AI Layer (#OPAL) now supports AnthropicAI's #Claude language models.

See comments for a #DataTwingler AI Agent demo executing #SPARQL and #SQL queries via a live #VirtuosoRDBMS instance.

Remember, query scope is SPARQL, #ODBC, or #JDBC accessible data sources.

Here's the #screencast demo of Grok generating a #SPARQL query results page for a #DBpedia #KnowledgeGraph query.

#Grok (v2) just passed my #SPARQL query generation test on the #DBpedia #KnowledgeGraph! It can now generate a link resolving to all movies directed by Spike Lee from my test prompt. x.com/i/grok/share... Links are shareable too—this is HUGE for #GenAI & #SocialMedia posts! #AI #LinkeData

Q: Can I fine-tune #ChatGPT using #SPARQL such that it basically becomes a #SmartAgent capable of querying across the massive #LODCloud #KnowledgeGraph, using natural language?

Yes!

Read: https://community.openlinksw.com/t/howto-chat-gpt-and-dbpedia-sparql-query-generation-from-natural-language-prompts/3823 -- which covers a basic example using #DBpedia (#Wikidata content in machine-computable and queryable form).

#SPASQL is how our #VirtuosoRDBMS enables declarative operations on data organized as tables or graphs via #SPARQL inside #SQL.

What are the benefits?

[2] Fine-grained entity relationship graph comprising clickable edges and nodes that function as #SuperKeys

#ChatGPT knows SPASQL too!

Problem:
How do I utilize the #DataAccess and #DataConnectivity that's already provided by #DBpedia using ChatGPT?

#LinkedData #SemanticWeb

For many years I've observed the following in parallel:

1. General confusion (and in some cases disdain) about the notion of a #SemanticWeb

2. Steadfast effort by a community to keep the vision going, stealthily, as exemplified by the #LODCloud (#DBpedia,, #Wikidata, #Uniprot etc..) and Schema.org (#SchemaOrg)

3. #DataSilos and all the impedance they inflict on the agility of individuals and enterprises alike on the rise i.e., #DataAccess and #DataFlow are still challenging, unnecessarily.

@openlink A new #DBpedia snapshot release available for service-specific and/or personal use from the @awscloud cloud.

In this age of #ChatGPT, the #LODCloud #KnowledgeGraph offers powerful #LinkedData gems that showcase the utility of a #SemanticWeb.

Enjoy!

Woot!

A brand new cut of #DBpedia that places #HTTP client apps and services right at the core of the massive #LODCloud #KnowledgeGraph.

Also note, in this revitalized #SemanticWeb era, #ChatGPT understand DBpedia -- pretty well :)

Wow!

Serious rollout flowing going here!

In 24 hrs we've been able to rollout on-premise installers comprising traditional installer programs (for #Windows, #macOS [including #AppleSilicon ports), and #Linux) and docker containers; ditto virtual machine bundles comprising a preconfigured and preloaded #DBpedia #KnowledgeGraph, what next?

You can also leverage benefits of the latest Virtuoso release combined with a preloaded and pre-configured DBpedia Knowledge Graph from the
Amazon AWS cloud.

@jonny ,
That’s the entire #LinkedData landscape to you?

I suggest you look a little differently, since it’s been working pretty well for a long time 😀

What do you need from a tool specifically?

A #DBMS (see #VirtuosoRDBMS that’s serves up #DBPedia and most of the #LODCloud nodes).

Browser enhancement, see @datasniff.

#Identity #Authenticity, see @youid.

I made two corrections:

1. corrected the content-type (changed text/rdf to text/turtle)

2. added missing xsd: prefix declaration

I used our #OSDS browser extension for view the embedded DBpedia Knowledge Graph.
