Monday, I’ll be speaking on “Linked Data” at the 49th German Market Research Congress 2014. In my talk, there will be many examples of how to apply the basic approach and measurements of Social Network Analysis to various topics ranging from brand affinities as measured in the market-media study best for planning, the
If you look at the investments in Big Data companies in the last few years, one thing is obvious: This is a very dynamic and fast growing market. I am producing regular updates of this network map of Big Data investments with a Python program (actually an IPython Notebook).
But what insights can be [...]
One of the most remarkable features of this year’s Strataconf was the almost universal use of IPython notebooks in presentations and tutorials. This framework not only allows the speakers to demonstrate each step in the data science approach but also gives the audience an opportunity to do the same – either during the session [...]
One of the most interesting Big Data companies in this network analysis of Venture Capital connections has in my opinion been Domo. Not only did it receive clearly above average funding for such a young company, but it was also one of the nodes with the best connections through Venture Capital firms and their [...]
As the data-base for the Big Data Investment Map 2014 also includes the dates for most of the funding rounds, it’s not hard to create a time-series plot from this data. This should answer the question whether Big Data is already over the peak (cf. Gartner seeing Big Data reaching the “trough of [...]
Here’s an updated version of our Big Data Investment Map. I’ve collected information about ca. 50 of the most important Big Data startups via the Crunchbase API. The funding rounds were used to create a weighted directed network with investments being the edges between the nodes (investors and/or startups). If there were multiple [...]
Once a year, the cosmopolitan digital avantgarde gathers in Munich to listen to keynotes on topics all the way from underground gardening to digital publishing at the DLD, hosted by Hubert Burda. In the last years, I did look at the event from a network analytical perspective. This year, I am analyzing the content, [...]
To fill the gap until this year’s Strata Conference in Santa Clara, I thought of a way to find out trends in big data and data science. As this conference should easily be the leading edge gathering of practitioners, theorists and followers of big data analytics, the abstracts submitted and accepted for Strataconf should [...]
A lot of people still have a lot of respect for Hadoop and MapReduce. I experience it regularly in workshops with market researchers and advertising people. Hadoop’s image is quite comparable with Linux’ perceived image in the 1990s: a tool for professional users that requires a lot of configuration. But in the same way, there [...]
One of the most intriguing tools for the Street Fighting Data Science approach is the new Google Trends interface (formerly known as Google Insights for Search). This web application allows to analyze the volume of search requests for particular keywords over time (from 2004 on). This can be very useful for evaluating product life-cycle [...]
In this blogpost I presented a visualization made with R that shows how almost the whole world expresses its attention to political crises abroad. Here’s another visualization with Tweets in October 2013 that referred to the Lampedusa tragedy in the Mediterranean.
But this transnational public space isn’t quite as static as it [...]
I am a regular visitor of Google’s research page where they post all of their latest and upcoming scientific papers. Lately I have thought whether it would be possible to statistically extract some of the meta-information from the papers. Here’s the result of the analysis of the papers’ titles produced with just a few [...]
Just a few months after Ogilvy & Mather created a new job position for a Chief Data Officer Todd Cullen, another WPP agency is following this example. Mindshare USA just appointed Bob Ivins as the company’s first Chief Data Officer directly reporting to the CEO Colin Kinsella.
Among the reasons for this [...]
In my PhD and post-doc research projects at the university, I did a lot of research on the new cosmopolitanism together with Ulrich Beck. Our main goal was to test the hypothesis of an “empirical cosmopolitanization”. Maybe the term is confusing and too abstract, but what we were looking for were quite simple examples [...]
Twitter has become an important communications tool for political protests. While mass media are often censored during large-scale political protests, Social Media channels remain relatively open and can be used to tell the world what is happening and to mobilize support all over the world. From an analytic perspective tweets with geo information are
