    Papamitsiou, Z., & Economides, A. (2014). Learning Analytics and Educational Data Mining in Practice: A Systematic Literature Review of Empirical Evidence. Educational Technology & Society, 17 (4), 49-64. This paper aims to provide the reader with a comprehensive background for understanding current knowledge on Learning Analytics (LA) and Educational Data Mining (EDM) and its impact on adaptive learning. It constitutes an overview of empirical evidence behind key objectives of the potential adoption of LA/EDM in generic educational strategic planning. We examined the literature on experimental case studies conducted in the domain during the past six years (2008-2013). Search terms identified 209 mature pieces of research work, but inclusion criteria limited the key studies to 40. We analyzed the research questions, methodology and findings of these published papers and categorized them accordingly. We used non-statistical methods to evaluate and interpret findings of the collected studies. The results have highlighted four distinct major directions of the LA/EDM empirical research. We discuss on the emerged added value of LA/EDM research and highlight the significance of further implications. Finally, we set our thoughts on possible uncharted key questions to investigate both from pedagogical and technical considerations.

    Which brings us to the underlying point of the piece - we are all leaving digital trails behind us, as we make our way around our individual lives. These trails are largely considered individual - even ethereal - yet technology is making these trails more visible and more readable everyday.

    Over the last year, I've produced five data-driven pieces for Wired UK. Four of them have been for the two-page infoporn spread that can be found in every issue. I've looked at the UK's National DNA Database, used mined Twitter data to find people's travel paths, and mapped traffic in some of the world's busiest sea ports.

    With so much technology and networking available at such low cost, what wouldn't you enhance? What wouldn't you connect? What information wouldn't you mine for insight? What service wouldn't you provide a customer, a citizen, a student or a patient?

Datawocky: More data usually beats better algorithms - 0 views

  • This simple change made Google's ad marketplace much more efficient than Overture's. Notice that the algorithm itself is quite simple; it is the addition of the new data that made the difference.
  • Of course, you have to be judicious in your choice of the data to add to your data set.
  •  
    But the bigger point is, adding more, independent data usually beats out designing ever-better algorithms to analyze an existing data set. I'm often suprised that many people in the business, and even in academia, don't realize this.

Daily Kos: UPDATED: The HB Gary Email That Should Concern Us All - 0 views

  • According to an embedded MS Word document found in one of the HBGary emails, it involves creating an army of sockpuppets, with sophisticated "persona management" software that allows a small team of only a few people to appear to be many, while keeping the personas from accidentally cross-contaminating each other. Then, to top it off, the team can actually automate some functions so one persona can appear to be an entire Brooks Brothers riot online.
  • Using the assigned social media accounts we can automate the posting of content that is relevant to the persona.
  •  There are a variety of social media tricks we can use to add a level of realness to all fictitious personas

  • Really? I thought. How do we know if those are real people? Twitter has to be the easiest thing to fake and to automate with retweets and 180 characrer max sentences. To the extent that the propaganda technique known as "Bandwagon" is an effective form of persuasion, which it definitely is, the ability for a few people to infiltrate a blog or social media site and appear to be many people, all taking one position in a debate, all agreeing, for example, that so and so is not credible, or a crook, is an incredibly powerful weapon.
  • I believe there are many people though who will base their judgment on rumors and mob attacks. And for those people, a fake mob can be really effective.
