DESCRIPTION
Altmetrics attempts to provide timely measures of an impact through the use of metrics from HTML views and downloads of scholarly articles, blog posts, tweets, bookmarks, etc. Publishers of scientific research have enabled altmetrics on their articles, open source applications are available for platforms to display altmetrics on scientific research and subscription models have been created to measure the use that research articles receive online. This presentation reviews some of the current models for providing altmetrics along with information on a selection the providers that have made altmetrics available for general use.

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

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
