Artificial intelligence: Better data processing and editing are key
In today’s age of digitalization and artificial intelligence, data is becoming an increasingly important asset for society. We live in a data-based and data-driven economy. New business models depend on the availability of reliable, up-to-date data that guarantees transparency and resilience. However, if this data is not properly processed and maintained, it is often useless. A team led by Professor Axel Polleres, head of the Institute for Data, Process and Knowledge Management at the Vienna University of Economics and Business (WU), has conducted a study to determine which data is actually important to people and developed methods to make data easier to use, for both people and machines.
Axel Polleres’ team worked with local communities to investigate the usability of data, looking at information on everything from the availability of business locations to activities for young people. This data was then compared with readily available public data. Relevant data that is precisely tailored to local needs is often difficult to find on open data catalogs, and in addition, is not available at the required level of granularity, the study found.
Algorithms filter data
To filter data more easily, Axel Polleres and his team have developed algorithms that automatically analyze these data sets and structure them using so-called knowledge graphs. This can not only support more intuitive and human-friendly search engines, but also improve the quality of the data. “For example, we can use knowledge graphs to locate individual datasets locally, then use them to build search engines that allow us to find all datasets related to a specific district, such as ‘Leopoldstadt' here in Vienna, even though the district name itself is not even explicitly mentioned in the data,” Polleres says.
