Our previous Do. Data events

Context, Data Science & Restaurant Reviews | 9 March 2023

Do.DataIn this workshop, we discussed what it means to be a data scientist and what sources are available for obtaining data outside of your company. We then looked at user-generated restaurant reviews to explore Context and Domain Knowledge and the importance they play in data science and analysis. This included insight into which visualizations tell the story the best. A lively discussion and an apèro rounded out the evening.

Data Journalism & Infographics | 24 January 2019

During the evening, Priska and Simon – – data journalists from Blick – – presented and took us through their journey to tell the story of the swiss airspace. This included insight into infographics, preparing and finding the data, problems that occurred along the way, as well as the digital and visual implementation. Using Tableau, we explored data analysis and visualization, and at the end we split into groups to create our own infographics and visualizations.

KNIME & Sentiment Analysis | 21 June 2018

During the evening, Vincenzo and Rosaria – – authors of the book on text mining “From Words to Wisdom” – – presented KNIME and took us step by step through the building of our own sentiment analysis application. This covered data access, text cleaning, stemming, dictionary tagging, text visualization and machine learning techniques.

AI & Image Recognition | 19 Apr 2018

During the event, we compared the photos of celebrities to those of terrorists to show how it’s possible for organizations such as the FBI to mistake someone’s identity if using only facial recognition detection. We also focused on how artificial intelligence can be applied by any organisation in the context of image recognition/classification and social media listening in order to constantly monitor users’ posts, comments and feedback (text or pictures), evaluate the sentiment, and react in a timely manner.

Contact us to understand how to quickly get started with artificial intelligence and image recognition within just a couple of weeks. We’ll show you how to leverage existing python packages, publicly available databases of images and other open-source resources. Or learn more about our Social Media Listening training course.

Big Data & Twitter | 19 Oct 2017

We compiled Twitter and relationship data on tweets from @realDonaldTrump from Twitter, Trump’s connections from BuzzFeed, and world’s richest people / most powerful people / top 2000 companies from Forbes lists. Whether it was storing or analyzing the data, the right tool was selected for the right job. Python to download the data from Twitter APIs. A document database (MongoDB) to store the JSON files. Tableau to analyze and visualize the Tweet patterns. Finally, a graph DB (neo4j) to analyze and visualize the connections/relationships. One insight was that Trump started to use paid marketing on Twitter at a time when his approval ratings dropped significantly, from visualizations of his tweeting patterns using Tableau. Another insight was based on a K-means clustering of Trump’s Twitter friends and followers. Surprisingly, not all of his followers were conservative-leaning, gun-rights protectionists. Rather, there were five distinct groups, including urbanites/professionals.

For more insights, check out our Tableau workbook below, download our presentation, and try out some of the Cypher queries in neo4j. Contact us if you’d like a copy of the Trump World neo4j database that includes all the data from Twitter, BuzzFeed, and Forbes lists.

New York City Taxis & Uber | 18 May 2017

In New York City, with a population of roughly 8.5M, there are over 750K taxi rides every day (incl. Uber, Lyft, etc.). The market leaders are Yellow Taxis with 42% of the market, followed by Uber with 30% (as of 2017). With data downloaded from NYC OpenData/Taxi & Limo Commission, 25M records for Dec 2016 were visualized in Tableau. One surprising insight is Uber has a higher market share of rides in upper Manhattan and the outer boroughs and lower market share in lower Manhattan, likely because they face stiff competition from the Yellow Taxis in lower Manhattan (designated the “Yellow Zone” by the NYC Taxi & Limo Commission).

See our Tableau workbook below for the full story. Disclaimer: The data has been limited to Dec 16 – 31 due to Tableau Public limitation of 15M records.

Australia’s Gender-Pay Gap | 23 March 2017

The Australian Taxation Office published tax data for the years 2013-2014, with average income broken out by gender and occupation. Not surprisingly, males had higher average incomes than females for the same occupation, across almost all occupations. Exceptions included futures traders and mountain guides. While the data has some interesting insights, it doesn’t alone tell us if there’s a difference in the average hourly wage of females and males.

Peruse our Tableau workbook with different charts to inspire you. Charts include a boxplot, scatterplot, dumbbell (using female/male icons), and distribution.
