SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Queries the Semantica knowledge graph to retrieve information using SPARQL, Cypher, and keyword search.

Core Features & Use Cases

  • Flexible query modes: SPARQL, Cypher-like, and keyword search to access graph data.
  • Structured graph patterns: support for common graph query patterns to model traversal and filtering.
  • Use Case: data discovery and analytics across linked entities with explainable results.

Quick Start

Ask the AI to run a SPARQL query against the knowledge graph to retrieve information for a given entity.

FAQPage Schema
How do I query a knowledge graph using SPARQL and Cypher?

You can query a knowledge graph using SPARQL, Cypher, and keyword search to retrieve information across linked entities. This Skill supports multiple query modes and structured graph patterns to model traversal and filtering for data discovery.

What is graph data discovery and when do I need SPARQL queries?

Graph data discovery is the process of retrieving information across linked entities using query languages like SPARQL. You need it for decision-support workflows requiring traceable, expressive queries and explainable results from a knowledge graph.

Can I use keyword search instead of SPARQL to find entities in a knowledge graph?

Yes, you can use keyword search as an alternative to SPARQL or Cypher. The Skill supports flexible query modes including keyword search, SPARQL, and Cypher-like patterns to access and retrieve graph data.

How do I model graph traversal and filtering patterns for linked data?

You model graph traversal and filtering by applying structured graph patterns within your SPARQL or Cypher queries. This approach supports common graph query patterns to retrieve and filter linked entities with readable, extensible outputs.

Does this graph query approach work for decision-support workflows?

Yes, querying the knowledge graph with SPARQL and Cypher directly supports decision-support workflows. It provides traceable, expressive queries that deliver explainable results for analytics and data discovery.

What are the limitations of using keyword search for graph analytics?

Keyword search retrieves graph data but lacks the structured graph patterns available in SPARQL and Cypher. For complex graph analytics requiring specific traversal, filtering, and traceable query outputs, structured query languages provide more expressive and extensible results.
