Abstract: Background: 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. 

Results: 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.

Conclusion: We have developed citations' prioritisation algorithm based on 
journal impact factor, forward referencing volume, referencing dynamics, 
and author's contribution level. It can be applied either to the primary 
set of PubMed search results or to the subsets of these results identified 
through key terms from controlled biomedical vocabularies and ontologies. 
NCI (National Cancer Institute) thesaurus and MGD (Mouse Genome Database) 
mammalian gene orthology have been implemented for key terms analytics. 
PubFocus provides a scalable platform for the integration of multiple 
available ontology databases. PubFocus analytics can be adapted for input 
sources of biomedical citations other than PubMed.
