Open Knowledge Maps
Free visual maps clustering the top 100 papers on any topic
Overview
Open Knowledge Maps is a free nonprofit service that clusters the top 100 results from PubMed or BASE into a visual topic map of any research field. No account needed; grant- and membership-funded, including City of Vienna basic funding for 2026.

Open Knowledge Maps turns a search query into an interactive map that clusters the top 100 documents from PubMed or BASE into visual topic groups — a fast, free way to get oriented in an unfamiliar field. It's a registered Austrian nonprofit, grant- and membership-funded, with City of Vienna basic funding secured for 2026; no account needed, no ads. The 100-document ceiling is the real constraint: maps sketch a field rather than survey it, and key papers can fall outside the cut. The AI is modest — text-similarity clustering, nothing generative — and quality depends on source-database metadata. Good for students, librarians and early-stage scoping; not a Scopus or Web of Science replacement, and not rigorous enough for systematic reviews.
What people say
Every map tops out at 100 documents. That one design decision defines Open Knowledge Maps: type a query, pick PubMed or BASE as the source, and in under a minute you get an interactive bubble chart clustering the top 100 hits into named subtopics. It's a sketch of a field, not a survey of one — important papers can fall outside the cut, and university library guides (Hong Kong PolyU among them) flag exactly that limitation.
Within that limit, it does its job well. Students and librarians use it to orient in an unfamiliar area before touching primary literature; researchers use it for early scoping. No account, no ads, instant results. The clustering is text-similarity grouping — honest, unglamorous machine learning, nothing generative — so the AI-tool label oversells it slightly.
The organisational story is unusual for this directory: a registered Austrian nonprofit since 2016, funded by grants and institutional memberships rather than a venture runway. Harvard Library lists it as a service, the City of Vienna granted it basic funding for 2026, and the VisConnect collaboration with IT:U Austria (2024–2026) is extending the technology into research assessment. Knowledge Futures Group recently became its first US institutional member. That model means no paywall creep — but also no guarantee of fast feature development, and map quality still rides on the metadata of the source databases.
Treat it as a free first step: quick orientation, a teaching aid, a scoping tool. For systematic work you'll graduate to Scopus, Web of Science or a dedicated review platform within a day, and that's fine — it never claimed to be those.

Notable facts
- Open Knowledge Maps generated over 100,000 research maps in its first 3 years with zero marketing budget — entirely through academic word of mouth.
- The platform was built by a former PhD student who was frustrated by the difficulty of finding entry points into unfamiliar research fields.
- Open Knowledge Maps won the European Commission's Open Science Prize in 2017, validating its mission to make science more accessible.
