SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill solves the challenge of finding, navigating, and mapping concepts across hundreds of disparate controlled vocabularies and thesauri, which are otherwise difficult to query in a unified way.

Core Features & Use Cases

  • Unified Search: Perform full-text searches across 648 international concept schemes including AGROVOC, EuroVoc, and Getty AAT.
  • Semantic Mapping: Bridge terms across different vocabularies using skos:exactMatch and skos:closeMatch links.
  • Use Case: A researcher can tag parliamentary documents against the UK Parliament thesaurus and simultaneously map those tags to international standards like EuroVoc or GEMET for broader interoperability.

Quick Start

Use the skosdex skill to search for the term climate change and retrieve its corresponding concept URI and scheme information.

Frequently Asked Questions about skosdex

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I search across multiple SKOS controlled vocabularies at once?

Search across multiple SKOS controlled vocabularies using a unified Solr full-text index that queries 648 international concept schemes simultaneously. You retrieve corresponding concept URIs and scheme information for metadata tagging.

Can I map terms between different thesauri like EuroVoc and AGROVOC?

Map terms between different thesauri like EuroVoc and AGROVOC by traversing skos:exactMatch and skos:closeMatch links. This bridges terms across disparate vocabularies for broader metadata interoperability.

What's the best way to run SPARQL queries for SKOS concept hierarchy traversal?

Run SPARQL queries for SKOS concept hierarchy traversal via an integrated Oxigraph SPARQL endpoint. This supports complex graph-based queries to navigate parent-child relationships and semantic similarity matching.

Does skosdex work with linked-data standards for document tagging?

skosdex works with linked-data standards for document tagging by indexing SKOS concept schemes. You can tag documents against specific thesauri and map those tags to international standards for broader interoperability.

What controlled vocabularies are included for semantic similarity matching?

Controlled vocabularies for semantic similarity matching include 648 international concept schemes such as AGROVOC, EuroVoc, Getty AAT, and GEMET. These cover broad domains for metadata tagging and information retrieval.

Why use a Solr full-text index for thesaurus label lookups?

Use a Solr full-text index for thesaurus label lookups to perform rapid text searches across hundreds of controlled vocabularies. This enables fast retrieval of concept URIs before executing complex graph-based queries.
