This page gives a good, quick idea what PubFocus does.

From BMC:

Understanding research activity within any given biomedical field is important. Search outputs generated by MEDLINE/PubMed are not well classified and require lengthy manual citation analysis. Automation of citation analytics can be very useful and timesaving for both novices and experts.

PubFocus web server automates analysis of MEDLINE/PubMed search queries by enriching them with two widely used human factor-based bibliometric indicators of publication quality: journal impact factor and volume of forward references. In addition to providing basic volumetric statistics, PubFocus also prioritizes citations and evaluates authors impact on the field of search. PubFocus also analyses presence and occurrence of biomedical key terms within citations by utilizing controlled vocabularies.

  1. Hi Michelle-

    Well, I think that most people will call a web-based application a mashup if it makes use of another party’s API. PubFocus clearly makes use of the NCBI Entrez API, so I think it could be called a mashup by this definition.

    The article mentions some other interfaces for PubMed data that might be called mashups in the same way because they use this API (though it could be argued that the ones that run on Java aren’t “web-based”, so it depends how loose you want to be with the definition of “mashup.”):

    SLIM (
    MedKit (
    PubMed Assistant (
    XplorMed (

    I think you already know about GoPubMed ( and ClusterMed (

    The article also mentions PubFinder (, but I haven’t been able to reach it today. I did reach its google cache, though:

    Best always,
