For the fun: PubMed and the End of the World!!!

leave a comment »

To read this nice post by the KraftyLibrarian:

If you haven’t heard about the  Mayan civilzation’s calendar predicting the end of the world on December 21, 2012, then you have been living under a rock.  Personally I believe the Mayans were on to something.  Instead, I believe the end of the world will happen on January 1, 2013.  Why?

As of January 1st NCBI will no longer support Internet Explorer 7 and all the hospitals that haven’t upgraded will begin to have problems searching PubMed. (…)

Reading: Is Google Scholar better than PubMed ?!

with 2 comments

According this study, PubMed searches and Google Scholar searches often identify different articles. In this study, Google Scholar articles were more likely to be classified as relevant, had higher numbers of citations and were published in higher impact factor journals.

PubMed: A few recent changes… (by Intellogist)

leave a comment »

Joelle Mornini, from the great Intellogist webiste, has listed a few recent changes that happened in PubMed.

In a few words, nothing revolutionary… Her conclusion is:

The filters sidebar replaces a cumbersome “limits” page that took a few extra clicks to access and apply to the search results.  Now, users can instantly refine their search directly from the results list.  The “sorted by computed author” search and the versioned citations both help users more quickly rank and identify the most relavent results or versions of a result.  The “Save items” portlet and “Citation manager” option allow the user to quickly compile and export the most relevant results into a concise list that can be manipulated through any type of citation manager software.  These subtle changes to the PubMed interface may not seem like enormous improvements, but they can save a prior art searcher time when every second counts

See the full article at:

Mornini, Joelle. 5 recent changes to the PubMed interface, Intellogist, 19 June 2012. Available from: http://intellogist.wordpress.com/2012/06/19/5-recent-changes-to-the-pubmed-interface/ [Accessed 20 June 2012]

Personaly, I would rather say that switching to great alternatives such as GoPubMed, PubGet or Biblimed, instead of using this poor PubMed will save precious minutes!!! See my previous post

iPubSci: an alternative to expensive science journals?

leave a comment »

iPubSci is a new concept for the downloading and purchasing of science articles on a per-article basis.

It could be a real-world solution to the access and affordability problem faced by scientists in both biotech and academia.  iPubSci would meld two already well-designed types of programs in search (PubMed) and the sale of individual pieces of content (iTunes). This concept arose out of numerous brainstorming sessions with Seattle biotech librarian Molly Bernard.

This initiative is developped by Stewart Lyman, a science-for-free activist, that I have already mentioned when he wrote in Nature Biotechnology.

Steward is looking for support of end-users at  biotechnology, pharma, medical devices, and in academia. He hopes to put additional pressure on commercial publishers to low the cost of articles.

With a librarian, it is better!!!

with one comment

A recent study has has found quantitative evidence of a significant difference in search performance between paediatric residents or interns assisted by a librarian and those searching the literature alone.

Each participant searched PubMed and other online sources, performing pre-determined tasks including the formulation of a clinical question, retrieval and selection of bibliographic records. In the assisted group, participants were supported by a librarian with ≥5 years of experience. The primary outcome was the success of search sessions, scored against a specific assessment tool.

Semantic MEDLINE: the next PubMed?

with one comment

The NLM works on a new interface for PubMed, including latest advances of semantic search (NLP and connected graphs).

Semantic MEDLINE is a prototype Web application that summarizes MEDLINE citations returned by a PubMed search. Natural language processing is used to analyze salient content in titles and abstracts. This information is then presented in a graph that has links to the MEDLINE text processed.

Currently, the results from 35 PubMed searches (including a variety of disorders and drugs) are available to be processed. The 500 most recent citations (from the date of the search) are available for further processing by Semantic MEDLINE”.

The prototype can be tested at:

Laser medicine: Scopus and Pubmed are the best sources

leave a comment »

Summary
The four most popular search engines PubMed/MEDLINE, ScienceDirect, Scopus and Google Scholar are investigated to assess which search engine is most effective for literature research in laser medicine. Their search features are described and the results of a performance test are compared according to the criteria (1) recall, (2) precision, and (3) importance.
As expected, the search features provided by PubMed/MEDLINE with a comprehensive investigation of medical documents are found to be exceptional compared to the other search engines. 

However the most effective search engine for an overview of a topic is Scopus, followed by ScienceDirect and Google Scholar. 

With regard to the criterion “importance” Scopus and Google Scholar are
clearly more successful than their competitors.

All in all Scopus is the most effective search engine if one requires only an overview of the topic.  For a widespread and in-depth investigation in the area of life science and closely related topics, PubMed/MEDLINE is more  appropriate
