About Open Knowledge Maps

Open Knowledge Maps turns a search on a research topic into a visual map, grouping relevant outputs by concept so you can get an overview of a field and spot important areas. It searches more than 400 million outputs in over 400 languages from more than 11,000 sources via BASE, covering 25 output types including publications, datasets and software.

An AI mapping mode is in beta, with results based only on underlying metadata. It is run by a charitable non-profit and funded by supporting member organisations.

Strengths

  • Very large index of open research outputs
  • Covers datasets and software, not only papers
  • Free and non-profit

Limitations

  • AI mapping is still in beta
  • Maps are built from metadata, not full text
