The Structure of Collaborative Tagging Systems

Posted

Fantastic article by Golder & Huberman from 2005 observing patterns of tag use on del.icio.us. All of it is good, including a great discussion of various forms of ambiguity etc in tagging and the relative merits/demerits of taxonomies vs folksonomies, but the really interesting bit comes towards the end when they observe, and attempt to account for, a remarkable and stable consensus on proportions of tags used to categorise resources. They relate this to the stochastic urn model, observing that some of the stability is the result of imitation (what I have called mob behaviour) but some of it is to do with shared and presumably independently held knowledge (what I have called multitude behaviour).

26 Reasons What You Think is Right is Wrong

Posted

A nice collection of cognitive biases that seem very relevant to social software and social navigation in particular.
I suspect that there are ways that most of these biases could be used positively in a learning context, though whether the bad habits acquired in doing so would be more harmful than the good they might engender would have to be considered carefully!

The (Bayesian) Advantage of Youth. Many-to-Many:

Posted

Typically brilliant article by Clay Shirky who once again elegantly proves a thing that, once you know it, is completely and intuitively obvious but that, before then, is just one of life’s curious puzzles. Of course – young people do interesting, creative and novel things and exploit new technologies more easily because they know less. This is the downside of wisdom – the more you know, the more you ignore the little anomalies, the more some things seem obvious and are not questioned.
Clay suggests that this is a real and unassailable advantage of young over old, but I think there is still a chance for us oldies. They key is to completely change your intellectual and/or working life every now and then. Not just a gentle shift from one job to another that is similar, or picking up another skill that draws on your existing skills (e.g. a new language), though that can probably help, but something utterly different and, on the face of it, unrelated to what you have done before.

A new twist on anti-spam tech can help digitize books

Posted

OK, this is really cool – putting the time spent on filling in CAPTCHAs to good use to harness the wisdom of the crowd in a big big way – 60 million eyes a day, solving problems that computers cannot solve. Brilliant idea, so many possible applications apart from the simple task of fixing weaknesses in OCR.
Just a little worrying that it could be a tempting target for coordinated practical jokers and maybe worse – CAPTCHA-bombing could be the next big thing 🙂

BibMe – the fully automatic & free bibliography maker (MLA, APA & Chicago)

Posted

as the title says – generates bibliographies in a small number of popular styles for inclusion in papers etc. The neat part is that the bibliographic database is generated by everyone who uses it.Simple idea, with collective intelligence.
