Use Open Knowledge Maps to find useful literature and visualise related topics and research areas with AI.

Open Knowledge Maps (OK Maps) is a web-based visualisation tool that facilitates exploratory research by mapping  literature using AI. It reveals related but often overlooked research topics, giving you an at-a-glance picture of multiple bodies of literature. 

Enter your research topic on the OK Maps search page to generate an interactive knowledge map of 100 journal articles from two major academic databases (PubMed or BASE).

• Articles are identified by relevance to your search term and arranged by similarity.
• Bibliographic citations are provided to the right of a map, with links to open access versions of the articles whenever possible.
• Searches BASE and PubMed:
  • BASE: is one of the world's most voluminous search engines especially for academic web resources. The index contains more than 400 million records from more than 11,000 content providers. You can access the full texts of about 60% of the indexed records for free (Open Access). 
  • PubMed: comprises more than 37 million citations for biomedical literature from MEDLINE, life science journals, and online books.

A digital library portal for researchers in fields like astronomy, earth science, heliophysics, physics, and planetary science, operated by the Smithsonian Astrophysical Observatory under a NASA agreement. It maintains four collections covering these disciplines, with over 20 million records, including refereed publications and preprints from arXiv, ESS Open Archive, and EarthArXiv. SciX provides searchable access to abstracts and full texts, and tracks citations and usage to enhance research discovery and evaluation.
