GoPubMed

An interesting use of facets based on an ontology. Sorting abstracts according to the concept hierarchies of GO and MeSH enable a combined search in molecular biology and medicine. The “What” categories help to systematically explore the results. The tree displayed to the left of results serves as table of contents in order to structure the millions of articles of the PubMed/MEDLINE data base. By navigating the tree users can narrow down from thousands of search results to a few in seconds.

GoPubMed retrieves PubMed abstracts for a search query and sorts relevant information to the 4 top level categories:

• What
• Who
• Where
• When
