Emerging Media Roles

many-to-many pattern

For the first time, media is natively good at supporting these kinds of conversations

carriage

Media is not just a source of information, it is increasingly more a site of coordination

producers

Members of the former audience can now also be producers and not just consumers

Citation Counting

Slow and uncited

Peer-review

Slow, encourages

conventionality, and fails to hold

reviewers accountable.

Scientific Reach and Range

Each day, scholarly articles receive

about 12.000 new mentions across

social media, news and blogs

Mentions renge in complexity, from quick shares to comprehensive

reviews

That’s 1 mention

every 7 seconds

Each week, about 20.000 unique

articles are shared

Alternative Metrics

“Altmetrics”

#Traditional Metrics

ALTMETRICS

Jason Priem (2009)

Non-Traditional Forms of Impact

Complementary to Traditional Citation-Based Analysis

Not ”alternative to citations”

“Bibliometrics mined impact on  the first scholarly Web.

Altmetrics mines impact on the next one.”

research questıons

Is the impact of an article on the Internet sensitive enough to forecast an increase in citations?

Are “impact factors” and “total citation numbers” of the journals in which there are articles, having high impact (Altmetrics values) values higher?

Do metric statistics show changes over the years?

Can Tweets Predict Citations?

Articles in top quartile by tweets after one week are 17 times more likely to be in top quartile of citations later.
