ConceptNet

What it is ConceptNet is a freely available, open multilingual semantic network intended to help computers understand word meanings. It combines knowledge originating in Open Mind Common Sense with other crowdsourced, expert-created, dictionary, encyclopedia, ontology, and game-derived sources.

Key concepts ConceptNet exposes relational assertions as Linked Open Data through a JSON-LD API, including relation, start and end concepts, source attribution, surface text, and weight. ExternalURL links connect terms to resources such as WordNet, DBpedia, and OpenCyc; ConceptNet also provides multilingual, cross-language-aligned word embeddings designed to avoid harmful stereotypes.

How you’d use it Browse concepts or query the REST/JSON-LD API for general relational knowledge, follow external vocabulary links for additional information, or use its published embeddings for word similarity and analogy tasks.

LLM angle none stated

Pitfalls & lessons The graph aggregates heterogeneous sources, so retain the assertion-level source metadata when provenance matters. Follow the site’s attribution guidance and review the CC BY-SA 4.0 licensing details before redistributing data.

Verdict A practical multilingual source of general word- and concept-level relationships with an accessible linked-data API.
