Riporto il post di Mark Patterson che ci aggiorna
sulle politiche di PLoS riguardanti le metriche.
Per approfondimenti rimando alla presentazione di
Peter Binfield "PLoS One: background, future
development, and article-level metrics"
pubblicata negli atti di ELPUB 2009:
L'impatto che il diffondersi di nuove metriche
puo' avere sull'Open Access e' enorme, non solo a
mio avviso. Solo la massima disponibilita' in
rete della letteratura puo' garantire la
diffusione necessaria a migliorarne le
performance. Un quadro in un museo aperto al
pubblico avra' molte piu' chances di essere visto
(e giudicato) rispetto ad un quadro di una
collezione privata dove questa possibilita' e'
data a pochi eletti (nel caso delle riviste, agli abbonati).
Article-level metrics at PLoS – addition of usage data
Submitted by Mark Patterson on Wed, 2009-09-16 11:10.
As part of our ongoing article-level metrics
program, we’re delighted to announce that all
seven PLoS journals will now provide online usage
data for published articles. With this addition,
the suite of metrics on PLoS articles now
includes measures of: online usage; citations
from the scholarly literature; social bookmarks;
blog coverage; and the Comments, Notes and ‘Star’
ratings that have been made on the article.
recently, we at PLoS feel that there is much to
be gained from assessing research articles on
their own merits rather than on the basis of the
journal (and its impact factor) where the work
happens to be published. Until recently, however,
readers have simply not had suitable tools to
give them any indication of the quality (or
‘impact’) of an individual article. With the
advent of online publishing and a burgeoning
array of third parties providing information on
scholarly articles, it has finally become
feasible to provide meaningful article-level
metrics and indicators for readers.
PLoS has therefore embarked on a program to
aggregate a range of available data about an
article and place that data on the article
itself. The data are found on the new tab called
‘Metrics’, available on all articles. A reader
can now scan the various metrics to determine the
extent to which the article has been viewed,
cited, covered in the media and so forth. With
the addition of usage data to the article-level
metrics we have taken another step towards
providing the community with valuable data that
can be used and analyzed. In order to make
article-level metrics as open and useful as
possible, we are providing our entire dataset as
and we encourage interested researchers to
download the data and perform their own analyses.
We will be updating this spreadsheet
periodically, but on launch the data it contains
are correct up to July 31st, 2009. Future
developments in our article-level metrics program
will include the provision of more data for each
metric (whenever we can locate high quality
sources) and new indicators as they arise, as
well as the development of more sophisticated
display and analysis tools on the site itself.
We believe that article-level metrics represent
an important development for scholarly
publishing. While some publishers are providing
limited data, we are not aware of any publisher
that has gone as far as PLoS in providing such a
broad range of indicators and metrics, and in
making the data openly available. We invite you
to visit our journal sites and seek out the Metrics tab for each article.
It’s also important to emphasize that online
usage should not be seen as an absolute indicator
of quality for any given article, and such data
must be interpreted with caution. To provide
additional context and to aid interpretation, we
have provided a series of
tables indicating the average usage of categories
of article (grouped by age, journal and topic
area). Users will also notice that a number of
articles do not have any usage data, because of
problems with the log files. We are working hard
to add data for these articles, and we also
encourage readers to let us know if they find any
anomalies or have any questions about the data.
More information about our article-level metrics
program can be found in our
website, as well as in this page of descriptive
text for each journal (e.g for
ONE). We look forward to your feedback, and to
further developments in article-level metrics.
