Big Data Analytics

The research group is concerned with the possibilities of Big Data analyses: from the generation of new data sets to the combination of already existing data sets and the application of Big Data methods.

Content element with id 1034

Today, a wealth of new data is becoming available from such sources as sensors, the Internet of Things, and the use of social platforms. This geometric rise in data volumes is leading to the increasing use of big-data analyses with their ability to exploit untapped potential in many fields of business. However, generating this data and making meaningful use of it requires special technologies, approaches and systems. The IW’s Big Data Analytics Research Group deals with the different aspects of big data but with a special emphasis on economic questions.

 

Our main points of focus

  • Structured and unstructured data generated by new methods and technologies, such as Internet searches, website content, social media information and price information from Internet shops and auction platforms
  • New ways of linking data sets
  • Application of big-data methods such as machine learning to economic questions
  • Application of big data in business research
  • Identification of statistical twins by means of survey data, Internet data and machine learning (companies and households)
  • Expanding on official statistics, for example, for the labour market
  • Analysis of regional infrastructures

 

Example of current research work

The research group uses various analysis methods and approaches. In principle, Big Data methods can be applied to all relevant economic questions. One example is the network analysis based on text analysis, here exemplarily with regard to the German actors in the Covid-19 research.

The collection of regional price data by means of web scraping is another project of the research group. As an example, the prices for heating oil at zip code level in March 2021 are shown here.

The analysis of social media texts is also part of the research group's method portfolio. The following application example is a tonality analysis of tweets on the topic of artificial intelligence in 2018 and 2019.
