Budapest, December 12, 2016 18:00

This weekend Telekom organized the Leading Data Hackathon developer contest with the total prize of two and a half million HUF where everything was revolving over Big Data (huge data pools). The participants were given an anonymized customer database comprised of 150.000 lines and based on this database they had to create apps in “data visualization”, “data representation interface”, and “database apps” categories. There were 25 contesting teams of 80 university students and Big Data experts.  One of the category winners provides a solution for Telekom to avoid calling customers with marketing offers at inconvenient times.

In the last 15 years the fixed line and mobile network infrastructures have been continuously expanding while there is a revolutionary increase of the number of equipment connected to the network through sensors and various applications. A huge amount of data is generated on a daily basis that requires stronger technologies and devices that can cope with the task of storing and processing this bulk amount of data. As a joint effect of these factors new business applications have been created on the basis of the data that collect and analyze information on a given enterprise or institution thereby helping to understand the day-to-day business activities from a new perspective. From the view of corporate and organizational competitiveness Big Data solutions, focusing on the interpretation and re-use of company and institutional data, are becoming increasingly important.

“We would like to become a key player of the Hungarian Big Data ecosystem and this is why it is important for us to provide an opportunity for data experts to meet each other at inspiring events, like this year’s Hackathon. During this weekend's contest we saw numerous very high quality solutions that the company would like to develop further” - said Mátyás Dobó, Magyar Telekom’s product development director.

The participants were given the data at the beginning of the contest and they had to prepare their solution within 24 hours. The winners of the categories were given 500.000 HUF whereas the second place was awarded with 200.000 HUF. Those who won the special awards were given 100.000 HUF.  The jury was comprised of experts from Telekom, T-Systems Hungary, Eötvös Loránd University and Kitchen Budapest.
