The problem

The problem we are addressing originates at a transportation company. When analyzing the results of their shipments, they would like to break this down into categories. For example, how many packages contain clothing and how many contain laptops, and does different content lead to different results during shipment. Instead of having to manually label all these packages, we look for a more efficient solution. The goal of this blog post is to show you the steps we took to solve this problem using machine learning. Steps that can be followed when you undertake your own machine learning projects.

The world of education is changing more than ever. Since the emergence of the internet, platforms for e-learning are becoming omnipresent. The use of video lectures and other online learning materials are rapidly replacing traditional lectures and textbooks. As learning is occurring more and more online, teachers are facing new challenges. The increasing distance between student and instructor asks for new tools to track and adjust learning activities.

From relational database to valuable event logs for process mining – A procedure

Posted on by

The huge potential of process mining applications is -luckily- already discovered in a variety of business settings. In industry, more and more companies are learning about its potential value. In meanwhile, academic researchers continue their quest to the best algorithm, the most meaningful metrics, the most understandable visualisations, etcetera. Whatever ‘best’, ‘meaningful’, and ‘understandable’ may be… These are food for thought and discussion on their own. But I’d like to address a different mini-research-topic-on-its-own: the event log.

An implicit assumption in process mining (both research and applications), is the existence of an event log.

Should everything that happens within your company be represented as an activity?

The picture above shows a list of possible actions that might be going on in an organization. As a process modeler, would you include all of them as activities in your diagram? Or do you think some are too detailed or rather not detailed enough to be considered an activity? Maybe you even argue that some of them are not relevant enough to figure in a process at all…

Students Business Informatics organized their first Service Jam

Three weeks ago, the students from ‘business and information systems engineering (BI)’ at Hasselt University organized a service jam #servicejamhasselt.

“A service jam resembles a musical jam session: you take your instruments and start to experiment. The idea is to make fun and start creating, not only brainstorming.” says Geert Tewissen, service designer at Boondoggle.

Many times the creation of new products starts from the possibilities these products can offer: the solution. Yet ideally, a new product should stem from a problem. This is certainly the case for IT-driven products and services. The stream of design thinking provides counterweight to this solution-based approach. A solid service design pulls you back to the origin of your business: which problem of which person(s) are we going to solve?
