Identifying Influencers on Twitter

April 16th, 2011 · 26 Comments

One of the perks of working at LinkedIn is being surrounded by intellectually curious colleagues. I recently joined a reading group and signed up to lead our discussion of a WSDM 2011 paper on “Identifying ‘Influencers’ on Twitter” by Eytan Bakshy, Jake Hofman, Winter Mason, and Duncan Watts. It’s great to see the folks at […]

LinkedIn Signal = Exploratory Search for Twitter

October 2nd, 2010 · 11 Comments

I like Twitter. Yes, I know that a lot of its content is noise. But I’ve found Twitter to be a useful professional tool for both publishing and consuming information. Publishing to Twitter is the easy part: I publish links to my blog posts and occasionally engage in public conversations. Consuming information from Twitter is more […]

Overcoming Spammers in Twitter

August 2nd, 2010 · 3 Comments

As I blogged a few months ago, University of Oviedo professor Daniel Gayo-Avello published a research paper entitled “Nepotistic Relationships in Twitter and their Impact on Rank Prestige Algorithms“, in which he concluded that TunkRank was the best of the measures he studied for ranking Twitter users. I recently discovered that he and David Brenes posted slides from […]

The War on Attention Poverty: Measuring Twitter Authority

July 13th, 2010 · 6 Comments

I gave this presentation today at AT&T Labs, hosted by Stephen North of Graphviz fame. The talk was recorded, but I don’t know when the video will be available. In the mean time, here are the slides. The audience was very engaged and questioned just about all of the TunkRank model’s assumptions. I’m hopeful that as […]

Are Ashton Kutcher and Puff Daddy the Most Influential Twitter Users?

March 20th, 2010 · Comments Off

In a post on ReadWriteWeb, Sarah Perez summarizes “Measuring User Influence in Twitter: The Million Follower Fallacy“, a recent research paper by Meeyoung Cha, Hamed Haddadi, Fabricio Benevenuto, and Krishna Gummadi. The punch line should hardly be surprising to regular readers here given my variety of rants on the subject: follower count isn’t great measure […]

Twitter Lists as an Influence Measure?

November 1st, 2009 · 13 Comments

In “Using Twitter Lists To Judge Influence“, Todd Zeigler of the Bivings Report writes: I think Twitter Lists will end up helping separate the men from the boys when it comes to influence.  In addition to seeing a Twitter users follower count, we can now see the number of other Twitter users who have added […]

Is Twitter Planning To Monetize The Firehose?

October 8th, 2009 · 9 Comments

A few months ago, I wrote in “The Twouble with Twitter Search“: But the trickle that Twitter returns is hardly enough. I believe this limitation is by design–that Twitter knows the value of such access and isn’t about to give it away. I just hope Twitter will figure out a way to provide this access […]

Another Project to Measure Twitter Influence

September 3rd, 2009 · Comments Off

Just noticed that the Web Ecology Project has published “The Influentials: New Approaches for Analyzing Influence on Twitter“. The blog post includes a link to their full report. Their approach strikes me as a generalization of measuring retweets, but perhaps I’m giving it too cursory a read. I did compare their results to TunkRank: we […]

An Able Grape at the Helm of Twitter Search

August 13th, 2009 · 5 Comments

While I am an avid Twitter user (and apparently a tradeable commodity in a “Fantasy Twitter” game that some friends are playing), regular readers know that I’ve offered mixed reviews of Twitter Search. I’ve link-baited Summize founder and Twitter Chief Scientist Abdur Chowdhury here once or twice, but I understand that he’s no longer running […]

Are Spammers Taking Over Twitter?

June 27th, 2009 · 4 Comments

Until recently, I’ve noticed the occasional incdent where a Twitter “trending topic” was socially engineered by a spammer, usually by an application which auto-tweets on sign-up. But the problem seems to be getting noticeably worse. Just a few days ago Habitat, a furniture store, used the trending topics as hashtags–including one associated with the disputed […]
