Definition: altmetrics is the creation and study of new metrics based on the Social Web for analyzing, and informing scholarship.
Bottom line is opening a discussion on citations vs. impact. Traditionally, hiring, tenure and promotion and general scholarly value has been enumerated and based on metrics surrounding citations.
Bibliometrics is the information science that has been built around these measurements. Traditional – based on print journals and factors developed in the 50s-60s. Measurements of quality based on patterns of use.
Discipline-dependent, slow, dependent on indexing in JCR.Created in 1961, Institute for Scientific Information, acquired by Reuters.
Invented in 2005. Few publications with many citations due to publishing in a prestigious journal, or many publications with few citations each.A scholar with an index of H has published H papers each of which has been cited in other papers at least H times. The h-index represents both the number of publications and the number of citations per publication. Problems – doesn’t account for co-authors, is bounded by total # of publications, manipulated through self-citations.
Getting closer to altmetrics because the value of the thing (the article) is being weighed as itself. Again though citations can be inflated… bad research gets cited lots as people rip it to shreds. PLoS ALM started in 2009.
Citations do not have to be the only measure of impact.

altmetrics is the creation and study of new metrics based on the Social Web for analyzing, and informing scholarship.
The web has revolutionized everything except scholarly communication.
Altmetric.combookmarkletCurrently only works with PubMed, arXiv and/or a page with a DOI.
Altmetrics offers a depth and breadth of data about research products that we can and should be paying attention to.
Altmetrics provides rich metadata (public tags for the item) not just a number. Altmetrics offers a fairer evaluation, a faster evaluation, and utilizes the web for not just sharing research, but tracking it. Possible to have a “living CV” with your impact being measured constantly and reflected in real time.
Achieve broader impact, including greater citations, by sharing work more widely, in more formats. Maximize impact through open access. Academia.edu,FigShare, ResearchGate.

Citations vs. Impact Σ Impact > Σ CitationsThe sum of “impact” is greater than the sum of citations.
Bibliometricstechniques for measuring scholarship by citationCitation analysis – determining scholarly value based on number of citations Applies to journals (impact factor) individuals (h-index) and articles (citation impact).
Citations vs. ImpactImpact Factor Reuters Journal Citation Report (JCR) − the average number of times articles from ✕ the journal published in the past two years have been cited in the JCR year. calculated by dividing the number of citations in ÷ the JCR year by the total number of articles published in the two previous years.Ex. $1980.00 Journal of Human Evolution (Academic Press/Elsevier Science) Impact factor = 3.638
Citations vs. ImpactH-index aka “Hirsch Number” Attempts to measure both the + productivity and the impact of the published work of a scholar. Compensating for disadvantages in other citation − analyses. Shows quantity and quality of scholarly output relative to the scholars own work.Ex. h-index tools Dean Falk, Anthropology – Research area(s): Paleoneurology Web of Science h-index = 28 Google Scholar h-index = 30 Scopus h-index = 12

Altmetricstechniques for measuring scholarship by impactDefinition: “altmetrics is the creation and study of new metrics based on thesocial web for analyzing, and informing scholarship.”Impact analysis – determining scholarly value based on engagement orimpressionsaltmetrics proposes that citations are not the only, or even the best, techniquefor measuring impact, relative to the new ways scholarly works move, grow andare shared.
“These new forms reflect and transmit scholarly impact: that dog-eared (but uncited) article that used to live on a shelf now lives in Mendeley, CiteULike, or Zotero–where we can see and count it. That hallway conversation about a recent finding has moved to blogs and social networks–now, we can listen in. The local genomics dataset has moved to an online repository–now, we can track it. This diverse group of activities forms a composite trace of impact far richer than any available before. We call the elements of this trace altmetrics.”Image from ‘Altmetrics: An App Review’ – Stacy Konkiel altmetrics: A ManifestoURI: http://hdl.handle.net/2022/14714
Why? Today’s journals are the best scholarly communication system possible utilizing 17th century technology. Citation metrics are slow, neglect impact outside of academia, and neglect influential but uncited work. Journal Impact Factors are easily manipulatable, a trade secret and controlled by commercial interests. Research outputs are no longer just articles. data grey literature reports software web projects
