Two new search engines for searching the scientific literature are accessible free on the Web, Quertle and PubMed PubReMiner.
If you are interested in learning more about these search tools, please read on and view the examples…
Quertle provides relationship searching utilizing “Power Terms” for developing search strategies and retrieving relevant results. This provides a very unique way for locating information, as compared to the traditional method of searching for individual terms within documents. In the example below, searching with the Power Term $Diseases and the keyword penicillin, displays “Key Concepts” as relationships to the Power Term. Clicking on one of these terms (e.g., Hypersensitivity, Infection) will re-execute the search. Or selecting “Grant Applications” will provide results with links to NIH RePORTER.
PubMed PubReMiner provides results in the form of frequency tables. It is a very powerful tool for data mining based on a search strategy. One can view keywords, MeSH terms, author names and journals associated with a search. In the search example below for “peanuts and anaphylaxis,” one will notice that 73 of the journal papers in PubMed contained the MeSH term Arachnis Hypogaea with the subheading “adverse effects,” or that “Sampson HA” was an author in 25 of the 228 total results. Selecting the checkbox next to this author’s name or MeSH term, clicking “Search Again” and then “Go to PubMed with Query” will redirect the results to PubMed.
