    After visualizing chat room dialogue earlier this week, I thought it might be neat to try and visualize some Twitter dialogue from the #LAK11 course.  For some reason I thought it would be simple to extract tweets from Twitter for analysis.  It wasn't!  So if you happen to know an easier way please leave a comment.

    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.

    NodeXL is a template for Excel 2007 and 2010 that lets you enter a network edge list, click a button, and see the network graph, all in the Excel window. You can easily customize the graph's appearance; zoom, scale and pan the graph; dynamically filter vertices and edges; alter the graph's layout; find clusters of related vertices; and calculate a set of graph metrics. Networks can be imported from and exported to a variety of data formats, and built-in connections for getting networks from Twitter, Flickr, YouTube, and your local email are provided.

  • Curation is an important component in the process.
  • Curation is important – yes, it’s biased, yes it misses contributions, but it’s personal

  • I think we need to also focus on the human aspect of data, sensemaking, curation, and trust.

  • la falta de archivos y la integración de las conversaciones en otros espacios en el correo electrónico diario. Hay dos razones principales para ello: Queremos demostrar que si alguien quiere ofrecer un curso en línea abierta, que no es necesario para ejecutar su propio servidor o escribir su propio software. Nosotros no pedimos Stephen si podría funcionar este curso en su sitio

      programa que soluciones esto?
  • Lo que perder - y todavía estoy inquieto acerca de esta compensación - es el archivo integrada de la actividad en el curso. Puedo enviar un correo electrónico diario al grupo de Google. Yo enlaces agregados / deliciosa / diigo / enlaces Twitter y comentarios sobre mi página de Netvibes . El problema, sin embargo, es que Netvibes es más bien tonto. Simplemente deja el contenido de la página hasta que algo nuevo ha sido publicado. Si usted es el seguimiento de la actividad en Netvibes, es probable que gran parte del encuentro el mismo contenido hasta que se ha actualizado con nuevo contenido. La actividad no se archivan por fecha.
  • Para CCK11 (a partir del lunes), vamos a experimentar con la realización del curso sin un LMS y el uso de gRSShopper sólo para la interacción. En LAK11, una de las adiciones clave parece ser el papel de "Defensor curso" que Dave Cormier está cumpliendo.
  • Tony Searl está empezando a desempeñar un papel similar al agregar los blogs del curso y contenido en función de sus intereses.
  • Curación es un componente importante en el proceso.
  • Si bien la información está creciendo en la abundancia y las herramientas y algoritmos (minería de datos, visualización) se están desarrollando como soluciones, no podemos pasar por alto la importancia de la señalización y la construcción de sentido en los sistemas sociales

  • which data is more appropriate - BIG or small
  • most discussion about big data centres on quantity
  • other elements you mention – implication, new models, new decision making approaches – all flow from this abundance of data.
  • ...15 more annotations...
  • Increased data quantity requires new approaches
  • Is small beautiful? Look at the following links. Big Data, Small Data New Age of Innovation (Prahalad) So you like Big Data
  • reading on Insurers and the work done by Levitt and Dubner on Freakonomics tells us clearly that data not earlier thought relevant or causal can be an efficient predictor.
  • Secondly, strategies designed on BIG data
  • may overpower small data strategies
  • Thirdly, BIG data also has BIG impacting factors.
  • Fourthly, actions taken on BIG data will have big consequences,
  • Lastly, if everybody, big or small, started using BIG analytics, to make decisions
  • companies would anyway lose the competitive differentiator that analytics brings to them.
  • Corresponding to the question, how big does BIG need to be, the question I have is - how small really is small.
  • defining patterns that emerge from very small pieces of data (e.g. synchronicity)
  • how tools for SNA and analysis of BIG data can apply to Learning and Knowledge Analytics
  • at the other end it embraces how small changes can cause long term variations
  • not easy to analyze the small data
  • data that is small enough not to be generalizable

    De hecho cualquier persona puede poner el nombre de otra y observar las estadísticas de comportamiento de esa otra persona. Es por tanto, una herramienta de doble filo, permite comparar tu actividad con la de otros, pero por otra parte están controlando a qué horarios te conectas, a quien retuiteas, cuales son las palabras que más utilizas, etc. A mí personalmente me ha sorprendido mis propias acciones. A veces piensas que vas en una dirección y sin embargo estás performando otra. Si alguna persona lo prueba, me gustaría saber su opinión. Saludos

  • 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.
