PubMed Update

PubMed has announced two new updates. One is new functionality of its Automatic Term Mapping feature, and the other is a new Citation Sensor feature. Additionally, there is a new Advanced Search feature currently in beta mode that is being tested. Brief descriptions follow.

Automatic Term Mapping. The old Automatic Term Mapping was designed to recognize author names, journal titles, and MeSH terms when searched without field tags. This worked fine when an author or journal name was not the same as a MeSH term, but when that happened the search term was mapped to a MeSH heading and “Text Word” fields, not the author or journal fields – so the citation was missed. The new ATM has been modified to include author and journal field searches. Another ATM update relates to MeSH and journals translations. The new ATM now broadens these searches by searching individual words and multiple words in the “All Fields” field; multiple words are ‘ANDed’ together. Although ATM’s new design expands searches, it may provide less relevant results. Using field tags in the regular PubMed search box or doing field searches in the new (Beta) Advanced Search mode can focus strategies – and results. more

Citation Sensor. Citation Sensor displays results for searches using untagged terms that are characteristic of citation searching, e.g., author names, journal titles, and publication dates (e.g., woese c 1972). Citation(s) results are highlighted in a yellow area above the search results. more

NCBI Beta Version of Advanced Search. The Advanced Search is designed to provide more ease and flexibility to create your search strategy. It can be accessed from the main PubMed search page by a link next to the search box. The PubMed Search History, Search boxes with field options (including links to indexes when available), all PubMed Limits, and the Index of Fields / Field Values for Preview / Index search are all accessible and usable on the same page – a big and welcome change! Send your comments at the bottom of the search page via “Write to the Help Desk.” more

Online Clinic. There is a thirty minute NLM and the National Training Center and Clearinghouse (NTCC) online clinic on Thursday, July 17, 2008 (2:00 pm ET) to go over PubMed changes. It is limited to the first 300 that sign in that day, but will be recorded for viewing from the same page. more

Please let me know if I can help you with any questions about these updates.
