Reference implementation of SPEAR algorithm released
I have just released the “reference” implementation of our SPEAR algorithm. The library is written in the Python programming language, and should be straight-forward to use. You can install the library via Python’s setuptools/easy_install or download it from GitHub.
Here’s a quick example on how to use it:
-
>>> import spear
-
>>> activities = [
-
… (datetime.datetime(2010,7,1,9,0,0), "alice", "http://www.quuxlabs.com/"),
-
… (datetime.datetime(2010,8,1,12,45,0), "bob", "http://www.quuxlabs.com/"),
-
… ]
-
>>> spear_algorithm = spear.Spear(activities)
-
>>> expertise_results, quality_results = spear_algorithm.run()
Publication at Journal of Computational Intelligence
I’ve just received the notification that the joint paper of Ching-man Au Yeung and me, titled “SPEAR: Spamming-resistant Expertise Analysis and Ranking in Collaborative Tagging Systems”, has been accepted for publication by the renowned Journal of Computational Intelligence. Seems like the new year 2010 is starting well!
