KBS/Ontology Projects Worldwide

What it is This is an alphabetically indexed directory of knowledge-base, ontology, knowledge-representation, and related projects and groups. Its entries range across ontologies, languages, tools, methodologies, search and question-answering systems, lexical resources, and other collections.

Key concepts The page is a discovery list rather than a single ontology or formal specification. Representative entries include BFO as an upper ontology, Chimaera for creating, merging, and diagnosing ontologies, Common Logic as a standard language, ConceptNet as a commonsense knowledge base and NLP toolkit, UMLS as aligned biomedical vocabularies, and WordNet as a lexical reference system.

How you’d use it Use the alphabetical index to discover names and short descriptions of projects, then follow the listed pointers for deeper investigation. The page also invites readers to email the maintainer about related work that is missing.

LLM angle none stated

Pitfalls & lessons Despite the heading “Some Ongoing” projects, the page itself marks Carter as defunct and says the Twente Ontology Collection page no longer seems available. Several descriptions also preserve dated context, such as ConceptNet statistics “as of 2010,” so entries should be treated as leads rather than current-status verification.

Verdict A broad historical discovery index with useful taxonomy-by-example, but not a curated guarantee that every linked project is current or available.
