  1. Mendeley Readership Altmetrics for Clinical Medicine and Engineering? Ehsan Mohammadi1, Mike Thelwall1, Vincent Larivière2, Stefanie Haustein2 E-mail: e.mohammadi@wlv.ac.uk 1University of Wolverhampton. UK. 2Université de Montréal, Montréal, Québec, Canada.

  2. Citation is incomplete Limited to authors’ perspectives.(Schloegl & Stock, 2004). More appropriate for theoretical publications. 3-5 years times are needed for receiving citation

  3. Citation indicators are not able to give the full picture of research impact

  4. Usage Metrics are tasteful but.. They mainly employed local usage data. Downloaders are unknown. Data aggregation is not easy.

  5. Altmetrics as a solution? • Altmetrics is a new movement which tries to find complementary measures for traditional metrics based on scholars’ activities in social web platforms (Priem, Taraborelli, Groth, & Neylon, 2011). • Data collection is faster. • Data is more accessible. • Data coverage is global. • Diversity in data type (not limited to authors)

  6. Why Mendeley? Massive users Diversity of users Huge size of database Open API Global coverage

  7. Research Question What proportion of Clinical Medicine and Engineering articles are covered by Mendeley database? Are there significant, substantial and positive correlations between Mendeley readership counts and citation measures in Clinical Medicine and Engineering specialties?

  8. Method

  9. Findings We considered the coverage in Mendeley for different specialties based on the available unique records in Mendeley catalogue. Clinical Medicine articles had the higher coverage (71.6%) in comparison to Engineering and Technology (33.7%) papers. 1.5% of the overall founded records of both Engineering and Clinical Medicine were subjected to duplication.

  10. Findings There is a significant correlation between Mendeley readership and citation counts in all the investigated specialities. The correlation for clinical medicine overall (r=.561) is higher than for engineering (r=.501). Cancer (r=.604) and Materials Science (r=.682) had the highest correlations among clinical medicine and engineering specialties. Surgery (r=.451) and Computers (r=.414) had the lowest correlations among Clinical Medicine and Engineering and Technology specialties.

  11. Findings The median Mendeley readership counts were higher than the median citation counts for mechanical and computer engineering papers. This is due to that mechanical and computer engineering papers were read more and citied less.

  12. Limitations Readership is limited to the individuals who choose Mendeley for their reference manager. Our studied sample is restricted to journal articles while conference papers are important document types in engineering disciplines.

  13. Conclusions In almost all disciplines, the correlation is not strong enough to conclude that Mendeley readership and citation counts measure the same aspect of research impact. A likely explanation is that Mendeley captures broader scholarly activities from a variety of readers’ perspectives in comparison to citation counts. Hence, Mendeley readership data could be a useful supplementary measure to remedy some limitations of citation analysis for some applied specialities.
