Descriptions: From the website: "The purpose of NLM's Unified Medical Language System® (UMLS) is to facilitate the development of computer systems that behave as if they "understand" the meaning of the language of biomedicine and health. To that end, NLM produces and distributes the UMLS Knowledge Sources (databases) and associated software tools (programs) for use by system developers in building or enhancing electronic information systems that create, process, retrieve, integrate, and/or aggregate biomedical and health data and information, as well as in informatics research."

Descriptions: GoPubMed is an innovative, powerful search tool that combines the MeSH (Medical Subject Headings) and GO (Gene Ontology) terminologies to optimize the effectiveness of queries to PubMed- for everyone, but for molecular biologists in particular. Searching elicits results presented very quickly (maximum display: the most recent 1,000 citations), along with a sidebar presenting the full results in categorized, hierarchical groups of terms that help the user to focus in further- the producers of this search engine refer to it as a "knowledge-based semantic search." There are many more features to this search tool than can be described here.
