We have just released LigerCat v. 2.1 – with new features and faster search. LigerCat it is a tool that allows you to search PubMed using words or even a DNA/protein sequence. The articles retrieved are processed to create a tag cloud showing an overview of important concepts and trends. The Medical Subject Headings or MeSH descriptors are combined and weighted by frequency (more frequent terms have a larger font size) to create the cloud. Clicking on one or more MeSH descriptors in the tag cloud adds it to the box on the right of the cloud and LigerCat searched PubMed for those terms instantly. Selecting more than one term finds articles tagged with all selected MeSH descriptors.
- Publication History graphs – In the Articles Search a Publication History graph is displayed in addition to the MeSH tag cloud. This is an interactive graph. Mousing over the graph will highlight years and display the number of articles from that year that your search retrieved. Clicking on the bar for that year performs the search in PubMed and takes to that result page. In the Genes Search, the graph will not take you to PubMed but you still can see how many articles related to the query sequence were published in each year.
- Code snippet available so you can put a MeSH cloud on your blog or home page
