An inclusive data driven conversation

We welcome you to the fourth edition of Ladies of Data! An inclusive event for everyone who is interested in data science & diversity.

In the 2023 version of Ladies of Data, we focus on networks, from a data science perspective but also from a personal perspective. That is why the event will end with drinks, where you can meet, mingle and join discussions around different topics.


Theme: Everything is a Network

If we think of a network, social networks such as Facebook, Twitter or LinkedIn immediately pop into our mind since they are part of everyday life. However, these social networks we use to communicate online with selected groups of people are just one of many types of networks we encounter daily. If we take a train to commute to work, we are taking advantage of the railways’ network; if we make a bank transaction, we are part of a network that connects users to banks; If we buy a product online, we are connecting ourselves to a defined set of preferences about goods that also constitute a network; companies compete with each other in a network since most market offerings are related to multiple other offerings. Data scientists are increasingly aware of how crucial networks are to making sense of the world around us. Almost everything has a relational aspect that can be modeled as a network, and the few things that don’t, are likely still embedded in a network.

Talk by Doreen: Network analytics @

In this talk, I present how we implemented network analytics to combat fraud at I begin with a short introduction about fraud in the online retail industry, before delving into how we started using network analytics to detect big fraudsters who use multiple accounts. I will discuss the graph data model that we utilized, how we apply graph queries, and which algorithms can be run on these graphs. By the end of my presentation, you will have a better understanding of how network analytics can be a powerful tool for identifying and preventing fraud in the e-commerce industry.
