Can work on ontologies with Neo4j, including those based on OWL (Web Ontology Language). However, Neo4j alone is not an ontology reasoner.

Build a knowledge graph without an LLM for your RAG applications

Bridge the gap and unlock hidden potential within your unstructured data

Apache Parquet is an important part of the mainstream data stack. It provides a space-efficient, widely-supported way to exchange tabular data that can be used directly by various query engines.

New features include community summaries, local and global retrievers, running retrievers in parallel, and custom prompt instructions.

When (not) to use GraphRAG

Here is a usecase of an automated version of Sparnatural submitted as an example for Veronika Heimsbakk’s SHACL for the Practitioner upcoming book about the Shapes Constraint Language (SHACL). “ The Sparnatural knowledge graph explorer leverages SHACL specifications to drive a user interface (UI) that allows end users to easily discover the content of an RDF graph. What…
