A Milestone Blogging Anniversary

It’s hard to believe, but I’m celebrating my 10-year blogging anniversary! I’m filled with gratitude for those who have read, encouraged, and inspired me throughout this adventure. Without you, blogging would be only half the fun. Now, let’s take a moment to reflect on this incredible decade…

The Early Years: SAP and India (2007-2009)

It all started in 2007 when I decided to explore an internship abroad in India. I was studying Computer Science and decided to go for an internship abroad. China and India were on my shortlist. I decided for India, applied for a scholarship, and asked some companies for interesting project work. Before starting the adventure, I published my very first blog post to keep family and friends in the loop.

For the next seven months, I lived in Bangalore and worked for SAP Labs India to develop prototypes for mobile BI apps. I spent plenty of weekends exploring India and surrounding countries. After returning from India, I continued to work for SAP at their headquarters while finishing my degree in Karlsruhe.

CERN: Data and Discovery (2009-2012)

Surrounded by snow-capped mountains and Lake Geneva, CERN grabbed my attention at the end of my studies. CERN has tons of data: some petabytes! Challenge accepted. CERN is known for its particle accelerator Large Hadron Collider (LHC). We applied machine learning to identify new correlations between variables (LHC data and external data) that were not previously connected. This chapter was all about embracing the challenges of big data.

Capgemini and MBA: Expanding Horizons (2012-2015)

Back in Germany, my focus shifted to bringing Big Data Analytics to companies. To one company? No, to many companies! So instead of getting hired as Head of BI for an SME, I started to work for Capgemini. I had fantastic projects, designed data-driven use cases for the financial sector, and gave advice for digital transformation initiatives.

In order to keep in balance with all the project work, I dedicated many of my weekends to studies and got enrolled in Frankfurt School’s Executive MBA program. During my studies, I focused on Emerging Markets and visited a module at CEIBS in Shanghai.

Tableau and Futura: Innovation and Entrepreneurship (2015-201?)

I knew Tableau from my time as a consultant. It is an awesome company with a great product and a mission: help people see and understand their data. That’s me! Joining Tableau allowed me to assist organizations in transitioning from classic BI to modern self-service analytics by developing data strategies so that data can be treated as a corporate asset. This includes education, evangelism, and establishing a data-driven culture.

In the evenings I’m working for Futura Analytics, a fintech startup, which I co-founded in 2017. Futura Analytics offers real-time information discovery and transforms data from social media and other public sources into actionable signals.

What’s Next? A Glimpse into the Future

Currently, I’m excited to present my Data Strategy talk on TC17, accompanied by a TensorFlow demo scenario. I’m also learning Mandarin, the predominant language of business, politics, and media in China and Taiwan, for quite a while. Let’s see if that is going to influence my next steps… 🙂

Monkey Business: Always be Ready to Demo

The famous Tableau Superstore demo data set

Usually, I really don’t like looking on the screens of other passengers. On this early morning train from Frankfurt to Cologne, however, the screen of my seatmate caught my attention. Where have I seen the logo on his slide deck before? Two coffee sips later, it came to me: it was the logo of Monkey 47, a very delicious gin, distilled in the heart of the Black Forest. So I asked my neighbor: “Is that the Monkey 47 logo?”

He was happy that I recognized his brand and we had a small chat about gin and the Black Forest. Turns out his name is Thomas, and he is the head of Sales and Marketing for Monkey 47. Thomas mentioned that his team is planning a tour to promote Monkey 47 in a number of cities. That sounds similar to what we are doing with the Tableau Cinema Tour, so I showed him our Cinema Tour landing page and explained briefly who we are and what our mission is.

I asked him how he is organizing his data. Thomas revealed that he lives in Excel hell: “spreadsheets with thousands of rows and way too many columns”. This also sounded familiar. I opened up our Superstore.xlsx in Excel and asked: “Do your Excel sheets look like this?” Thomas replied: “Yes!”

Here we go! I drag’n’dropped the file on my Tableau desktop icon and paced through a 7-minute-demo ending with an interactive dashboard. Thomas was flabbergasted. To polish things off, I showed him the interactive Twitter Sentiment Dashboard embedded in my blog. Thomas grabbed his jacket and gave me a business card, saying: “We need Tableau!”

In 2013, Tableau introduced R Integration, the ability to call R scripts in calculated fields. This opened up possibilities such as K-means clustering, Random Forest models, and sentiment analysis. With the release of Tableau 10.2, we can enjoy a new, fancy addition to this feature: the Python Integration through TabPy, the Tableau Python Server.

Python in Tableau: The Perfect Blend

Python is a widely used general-purpose programming language, popular among academia and industry alike. It provides a wide variety of statistical and machine-learning techniques and is highly extensible. Together, Python and Tableau are the data science dream team to cover any organization’s data analysis needs.

In this tutorial, I’m going to walk you through the installation and connecting Tableau with TabPy. I will also give you an example of calling a Python function from Tableau to calculate correlation coefficients for a trellis chart.

Step by Step: Integrating Python in Tableau

1. Install and start Python and TabPy

Start by clicking on the Clone or download button in the upper right corner of the TabPy repository page, downloading the zip file, and extracting it.

TabPy download via GitHub web page

Protip: If you are familiar with Git, you can download TabPy directly from the repository:

> git clone git://github.com/tableau/TabPy

TabPy download via Git command line interface

Within the TabPy directory, execute setup.sh (or setup.bat if you are on Windows). This script downloads and installs Python, TabPy, and all necessary dependencies. After completion, TabPy is starting up and listens on port 9004.

2. Connecting Tableau to TabPy

In Tableau 10.2 (and later versions), a connection to TabPy can be added in Help > Settings and Performance > Manage External Service Connection:

Tableau main menu
Tableau main menu

Set port to 9004:

External Service Connection dialogue

3. Adding Python code to a Calculated Field

You can invoke Calculated Field functions called SCRIPT_STR, SCRIPT_REAL, SCRIPT_BOOL, and SCRIPT_INT to embed your Python script in Tableau:

SCRIPT_REAL('
import numpy as np
return np.corrcoef(_arg1,_arg2)[0,1]
',
SUM([Sales]), SUM([Profit]))
view raw corrcoef_python_tableau.txt hosted with ❤ by GitHub
Python script within Tableau
Python script within Tableau

4. Use Calculated Field in Tableau

Now you can use your Python calculation as Calculated Field in your Tableau worksheet:

7 Fragen, die Unternehmen helfen ihr Ergebnis mit Social Media zu steigern

Twitter Sentiment Analysis: klicken, um interaktives Dashboard zu öffnen
Twitter Sentiment Analysis: klicken, um interaktives Dashboard zu öffnen

Ist der Einsatz sozialer Netze in Ihrem Unternehmen auf Marketing beschränkt, und lässt dadurch Chancen ungenutzt?

Noch immer schöpfen viele Unternehmen in Deutschland die Möglichkeiten von Social Media nur unzureichend aus. Die meisten Firmen nutzen Social Media lediglich als Marketinginstrument, senden zum Beispiel in Intervallen die gleichen Inhalte. Wesentlich weniger Unternehmen setzen Social Media dagegen in der externen Kommunikation, in Forschung und Entwicklung, zu Vertriebszwecken, oder im Kundenservice ein.

Nachfolgend betrachten wir die Twitter-Kommunikation von vier Social-Media-affinen Unternehmen etwas näher, und zeigen anhand sieben Fragestellungen was sie anders machen und wo die übrigen Nachholbedarf haben.

1. Wann und wie werden Tweets gesendet?

Ein Blick auf das Histogram lässt auf reichlich Interaktion schließen (Tweets und Replies), während das Weiterverbreiten von Tweets (Retweets) eher sporadisch auftritt:

 

2. Wie umfangreich sind die Tweets?

Wie es scheint, reitzen die meisten Tweets die von Twitter vorgesehenen 140 Zeichen aus – oder sind zumindest nahe dran:

 

3. An welchen Wochentagen wird getweetet?

Am Wochenende lässt die Kommunikation via Twitter nach. Die Verteilung der Emotionen bleibt dabei gleich, unterscheidet sich aber von Unternehmen zu Unternehmen:

 

4. Zu welcher Tageszeit wird getweetet?

Auch nachts werden weniger Tweets verfasst. Bei Lufthansa kommt es dabei recht früh zu einem Anstieg durch Pendler-Tweets, etwas später tritt dieser Effekt bei der Deutschen Bahn ein: 

 

5. Welche Art der Kommunikation herrscht vor?

Der hohe Anteil an Replies bei Telekom, Deutsche Bahn und Lufthansa impliziert, dass diese Unternehmen Twitter stark zum Dialog nutzen. Unter den Tweets der Deutsche Bank ist hingegen der Anteil an Retweets – insbesondere bei jenen mit Hashtag – deutlich höher, was auf einen höheren Nachrichtengehalt schließen lässt:

 

6. Welche User sind besonders aktiv?

Nun betrachten wir die Twitter-User, welche die entsprechend Twitter-Handles der Unternehmen besonders intensiv nutzen:

 

7. Welche Tweets erzeugen Aufmerksamkeit?

Diese Frage lässt sich am besten interaktiv im Dashboard (siehe auch Screenshot oben) untersuchen. Entscheidend ist bei dieser Betrachtung die Ermittlung der Emotion durch eine Sentiment-Analyse.

Je nach Emotion und Kontext ist es vor allem für das adressierte Unternehmen von Interesse rechtzeitig und angemessen zu reagieren. So lässt sich eine negative Stimmung frühzeitig relativieren, und so Schaden an der Marke abwenden. Positive Nachrichten können hingegen durch Weiterreichen als Multiplikator dienen.
