Organizations are already collecting altmetrics

ScienceCard

and soon…

Publishers are already displaying Article-Level metrics

Article-Level Metrics or altmetrics? What are we talking about?

We’re talking about both

Article-Level Metrics (ALM) are a comprehensive and multi-dimensional suite of transparent and established metrics at the article levelhttp://article-level-metrics.plos.org/alm-info/

Altmetrics is the creation and study of new metrics based on the Social Web for analyzing, and informing scholarshipAltmetrics Manifesto - http://altmetrics.org/about/

Altmetrics data is aggregated from many sources

Altmetrics sources can be categorized

UsageHTML views, PDF/XML downloads (various sources – journal, PubMed Central, FigShare, Dryad, etc.)

CapturesCiteULike bookmarks, Mendeley readers/groups, Delicio.us

MentionsBlog posts, news stories, Wikipedia articles, comments, reviews

Social MediaTweets, Google+, Facebook likes, shares, ratings

CitationsWeb of Science, Scopus, CrossRef, Pubmed Central, Microsoft Academic Search

Relevant to the body of knowledge

Available in machine-readable form (API)

Immune to gaming

Free to redistribute (CC-0)

Ideal altmetrics source should provide data that is

PLOS Article-Level Metrics (ALM)

• The PLOS Article-Level Metrics project started in 2009

• Tracks usage, citations and social web activity for all PLOS articles

PLOS ALM application

ALMs on PLOS articles

PLOS Reporting and Visualization prototype

Added Benefit PAAS, value-added services

What are they building?• Next generation impact analysis metrics for

scholarly research• Aggregating artifact and author level metrics into a

research reputation graph• Clicks, views, tweets, likes, links, tags, favorites,

Google+, etc. will be captured and correlated

Plum Impact Reports

ScienceCard

• Created by Martin Fenner in 2010 as part of the PLOS/Mendeley Binary Battle

• Based on PLOS ALM application• Creates a baseball card metaphor for researchers

Free Yes

API Yes

Open Source Yes – Ruby on Rails

Added Benefit Based on researcher profiles

ScienceCard for Martin Fenner

ReaderMeter

• Created by Dario Taraborelli in 2010 to estimate the impact of a research article

• Based on the article’s usage at Mendeley • ReaderMeter adapts two popular impact metrics

for authors and redefines these metrics by using bookmarks instead of citations

Free Yes

API No

Open Source No

ReaderMeter for Duncan Watts

CitedIn

• Combination of a searchable database and webservice for citations citations in the literature, biomedical databases, blogs, books and wiki's

• Created by Andra Waagmeester, Bioinformatics of Maastricht University

Free Yes

Next step for altmetrics community

Provide context to the numbers

Provide an awesome use case

Create best-practices for collecting, aggregating, normalizing and displaying altmetrics data

Create strategies to combat gaming

Getting started as a librarian

Collect and track altmetrics • For research articles published at your university• For research of interest• Display altmetrics on author bios

Tell publishers that you want Article-Level Metrics for every published research article

Tell altmetrics sources that the data should be CC-0

Join the #altmetrics and altmetrics Google Group discussions

Getting started as a publisher

Collect and display altmetrics for the articles you publish

Work with an altmetrics service provider or install an Open Source altmetrics application

• Take into account cost, technical expertise, but also who owns the data

Join the #altmetrics and altmetrics Google Group discussions
