Search PubMed using words or even a DNA/protein sequence to create a tag cloud showing an overview of important concepts and trends. LigerCat aggregates multiple articles in PubMed, combining the associated MeSH descriptors into a cloud, weighted by frequency.
Medical Subject Headings (MeSH) is a controlled vocabulary created and maintained by the National Library of Medicine and applied to categorize and index journal articles in biomedical science.
Simply click on one or more MeSH descriptors in a tag cloud to instantly search PubMed for those terms instantly. Selecting more than one term finds articles tagged with all selected MeSH descriptors.
