Data4Good Hackathon: Solve interesting Data Science challenges and do good along the way

Data Science and Artificial Intelligence are creating a lot of buzz at the moment, and increasingly they are expected to contribute to the big challenges of our time – for example advancing the Sustainable Development Goals formulated by the UN. At the Data4Good Hackathon, we want to put the theory into practice, and we are looking for NGOs/social enterprises and Data Scientists, Designers and Developers to join us!

The Idea

In an intense, 2-day hackathon interdisciplinary teams of data scientists, developers and designers will work together with domain experts from NGOs and social enterprises to create new insight about their work, solve complex challenges and identify new social impact opportunities. This may be in form of statistical analyses and machine learning models, data visualizations or by linking existing data with new data sets – the teams have no boundaries on their creativity!

Participate as an NGO or social enterprise

Are you working in an organisation whose primary goal is to create positive social impact? Are you curious about better leveraging your data? Do you want to increase your impact through machine learning technologies? Then join the Data4Good Hackathon as a partner organisation.

We invite NGOs and social enterprises, as well as think-tanks and government agencies, etc to participate. You will need to nominate a contact person, who will liaise with the Data4Good team and participate in the hackathon.

Participate as Data Scientist

You want to hone your skills on real-life problems and create positive social impact at the same time? Then join the Data4Good Hackathon as a data science mentor.

Your role will be to develop a deeper understanding for the data and goals of an NGO, social enterprise or similar organisation, and to guide a team of 4-6 volunteer data scientists, designers and developers during the hackathon.


  • End of May 2018: Applications for the Data4Good Hackathon
  • End of June 2018: Selection of the 4-6 Hackathon projects
  • October/November 2018: 2-day Data4Good Hackathon (precise date to be announced)

Organised by the Vienna Data Science Group

We want to demonstrate that Data Science can be a major force for creating social impact.  By means of the Data4Good Hackathon, we want to foster a dialogue between NGOs, social enterprises, and Data Scientists. We will provide organisational and logistical support, and, in the run-up to the Data4Good Hackathon, help with shaping the problem and the required data.

Data Science for Social Good – Practical Examples

Dieser Artikel wurde im Original auf Deutsch von Daniel Kirsch von Data Science for Social Good Berlin veröffentlicht, und hier mit freundlicher Genehmigung und kleinen Anpassungen auf Englisch.

This article gives an overview of use cases and examples how civil society organisations can utilize modern analytical techniques (“Data Science”) for their goals. It was originally published in German by Daniel Kirsch of “Data Science for Social Good Berlin” and is translated and slightly adapted here with kind permission.

Big Data and Data Science have only recently caused significant public controversy. The large newspapers mainly discuss data protection and ethical issues of algorithms – certainly important topics. However, the potential for positive impact through a social-good oriented use of data analysis does not attract much attention.

Which is unfortunate: In many other parts of the world organizations like DataKind, BayesImpact or the “Data Science for Social Good”-Fellowships create social innovation. These initiatives enable NGOs to utilize predictive methods that are usually available only in an online advertisement or algorithmic trading. They also create attractive environments for data scientists to tackle problems of civil society. Data Scientists analyze and visualize for example the success of poverty reduction programmes or help to manage scarce fire protection resources more efficiently.

What exactly is Data Science? And with what kind of problems can Data Scientists help? In our talks with prospective partners, we noticed one common theme: Data Science is a very abstract and vague term. Many organizations we’d like to support don’t know where to start or how to make good use of modern data analysis in their daily work. For this reason, I collected and categorized a range of examples, to give interested readers from civil society organizations a better understanding of Data Science.

If you find yourself in one of the examples and want to know more, don’t hesitate to contact us! We’d like to support you.

Use cases

The use cases follow this structure: Problem, Solution, Example. Afterwards, there is a list with additional examples, many from DataKind or Data Science for Social Good Chicago.

Analyzing or Predicting Demand

Problem: You want to know how you can reach your target group, but you don’t have the required data to identify potential recipients.

Solution: Data Science helps to find alternative data sets that strongly correlate with previously undetected characteristics of the target group. A model then statistically predicts the demand for a certain group/region.

Example: GiveDirectly needed information about poverty in Kenya, but was lacking official statistics. Data Scientists helped to create a system that automatically detects the roof type in satellite images so that poverty levels could be estimated automatically.

Other examples:

Predicting Outcome

Problem: Data Science helps to estimate the results of your service for each individual case, so you can prioritize cases by impact or urgency. The model can also inform which factors contribute most to the outcome.

Solution: Amnesty International combats human rights abuses. Data Scientists were able to identify patterns in incoming requests for help from the Urgent Action Network. These patterns indicated which cases historically escalated to crises. New cases can now be assigned with an indicator of urgency.


Other examples:

Analyzing Impact

Problem: You want to understand whether your program/campaign/service leads to the desired results.

Solution: Data Scientists can conduct statistical analysis on existing data sets to analyze and visualize results. They can also advise which additional data sets may be useful, in cases where data on the results is not available directly.

Example: The Chicago Alliance to End Homelessness wanted to know which of their programs had the best successes. Data Scientists first defined the success metrics and then visualized the results.

Other examples:

Early Warning Systems

Problem: You want to find out, why recipients of a service or volunteers unexpectedly quit a program.

Solution: Data Science helps to detect patterns in this behaviour so that measures can be taken proactively to re-integrated persons into the program.

Examples: DC Central Kitchen also offers vocational training programs for socially deprived persons. An analysis of their data showed that participants quit the training just shortly before the training officially ends. Further analysis showed that participants with certain characteristics have a higher probability of quitting early. With this knowledge participants at risk can now be approached proactively to keep them in the program.

Other examples:

Fraud Detection / Detecting Misuse

Problem: You want to detect and prevent fraud or misuse of your services.

Solution: Data analysis of usage of your service identifies anomalous or suspicious behavior which may indicate fraud, waste, or misuse.

Examples: The local government of Los Angeles checks applications for social welfare benefits with the help of data analysis for anomalies, to pick cases where an extra review should be conducted.

Other examples:

Enriching Data

Problem: Your organization collects large amounts of data, however, this data is only available in unstructured form (e.g. PDF-documents or images).

Solution: Machine Learning (a method of Data Science) or Crowdsourcing, or a combination of both, enriches your data by automatically classifying images or documents or extracting data from them. The information gained here can then be used for other analysis, for example impact prediction.


Examples: UN OCHA works in the field of disaster recovery. In a case of a natural catastrophe they wanted to tag images from social media, if they show damages to infrastructure. Due to limited resources they could only tag a small amount of images. When the Typhoon Bopha struck the Philippines in 2012, the Digital Humanitarians re-used this small number of images to train an algorithm which in turn could tag a much larger number of images in a shorter amount of time.

Other examples:


Problem: Fundraising is another area where Data Science can help. Segmentation of donors and A/B-Testing are only two examples.


Data Science has a lot of potential for civil society organizations – which currently often stays unused. The use cases shown here hopefully make that potential more concrete and explain how data science can be used for the social good.

Out initiative is looking for partner organizations to work on concrete problems and demonstrate how to realize the potential.

The hackathon we are aiming for is modelled after the initial DataKind concept of a DataDive. In an intense, 2-day hackathon interdisciplinary teams of data scientists, developers and designers will work together with domain experts from NGOs and social enterprises to create new insight about their work, solve complex challenges and identify new social impact opportunities. This may be in form of statistical analyses and machine learning models, data visualizations or by linking existing data with new data sets.

Hints and further reading

Another source for ideas and examples is datalook – a portal where data-driven projects with a social-good goal can be published and discussed. The aim is to inspire readers to replicate projects.

DataKind categorizes the use cases differently – into descriptive insights, predictive insights and prescriptive insights. You can read their blog here.

The Nominet Trust (UK) published a report on the topic of Big Data and Social Organizations which is a good addition to this article.


A big thank you to Daniel Kirsch and DSSG-Berlin for writing the original article in German and the permission to adapt and re-use it here!
