About LigerCat

LigerCat was created as part of the Biology of Aging project at the MBLWHOI Library at the Woods Hole Marine Biological Laboratory.

LigerCat is a search tool for NCBI's PubMed that uses tag clouds to provide an overview of important concepts and trends. LigerCat aggregates multiple articles in PubMed, summing their MeSH descriptors and presenting them in a cloud, weighted by frequency.

Medical Subject Headings (MeSH) is a large controlled vocabulary created and maintained by the National Library of Medicine to categorize and index journal articles in the life sciences. MeSH descriptors are akin to tags in a blog post, but scientific articles are tagged with MeSH descriptors by respected librarians and scientists.

In addition to providing a visual overview of a set of PubMed articles, LigerCat can search PubMed in realtime. Simply click on one or more MeSH descriptors in a tag cloud to search PubMed for those terms instantly.
