Airflow: feedback on BL.Predict and Foundation use cases
Introduction In a context where the automation of data workflows has become a fundamental pillar of project reliability and scalability, Apache Airflow has established itself as an essential tool within the technical ecosystem of our BL Research team, dedicated to Research and Technological Innovation at Berger-Levrault. Whether orchestrating text document processing chains or driving transformations on IoT data, Airflow offers invaluable flexibility when properly mastered. Two use cases embody our
Knowledge at your fingertips: Building an Ontological Knowledge Base from our Editorial database
Our times are increasingly influenced by the prevalence of large volumes of data. These data most often hide great human intelligence. This intrinsic knowledge; whatever the field; would allow our information systems to be much more efficient in the processing and interpretation of structured and unstructured data. For example, the process of finding relevant documents
Automating the Detection of Duplicates in our Databases
Today’s complex applications for knowledge extraction and data mining use heterogeneous and distributed data. In this context, the quality of any decision depends on the quality of the data used. In fact, with the lack of accurate and reliable data, bad decisions can be made. In order to provide a better understanding of the source
Designing the right way to express constraints in a Java Architecture for Optimisation problems
We are often brought to solve problems with constraints in real life, such as: shopping in several distant stores, planning and organizing vacation expenses, or packing things in boxes during a move. Resolving these problems with constraints is not always easy. More particularly, when it comes to optimizing a set of criteria such as time,
Testing the migration of Graphical User Interfaces
Technologies and frameworks are not immortal, it’s a fact. For a software editor like us, it is regularly a necessity to migrate a framework to another. When you consider, large software like e-sedit for example, migrating the entire software in one shot is almost impossible. Many companies are migrating their software systems. And so, we
The Traceability chronicles – Episode 1: How logs can help you understand what your users do?
We start here a series of articles explaining some of our most interesting results with regard to traceability of applications. We will address the issues of automatic code instrumentation to trace the system by itself and the underlying difficulties. We will also discuss what constitutes a good, useful, and usable application trace. We will also
Citizen & Digital society
After signing the “RESET manifesto” published in Le Monde, Berger-Levrault is involved in a research collaboration with the association for the Foundation of a New Internet Generation (Fing), a reference think & do tank on digital transformations. This collaboration takes the form of two projects focusing on the theme “citizens and the digital society” from
When magic happens! Making Java and Visual Basic 6 dance together.
Visual Basic is a third-generation event-driven programming language belonging to Microsoft. It is based on the Component Object Model (COM) programming model and designed for beginners. The Last Version is the 6 (1998) and the core of FirmaDoc, our Spanish product dedicated to document and file management for public administration is written in VB6. However,
A Mobile Social Robot as a tool for Nursing Homes
Over the centuries, scientific advances in medicine, pharmacology, and various surgeries have allowed the population to age healthier for longer. Our life expectancy in France has therefore now reached the age of 85.6 for women and 79.7 for men (Papon et al., 2020). This increase in life expectancy suggests an increase in the aging population
What is Robotic Process Automation (RPA)? Our Complete Report.
About Top Illustration: « Built and unveiled for the first time in 1770, the Mechanical Turk or chess-playing automaton is a famous hoax built at the end of the 18th century: it was an alleged automaton with the ability to play chess. It was partially destroyed in a fire. Nowadays a replica has been created: it
Software Traces for Detecting Frauds in BL.Enfance
Fraudulent behaviors can be detected based on the applicative traces. In this work, we used application traces from BL.Enfance, one of our software dedicated to children’s activities billing and management. We specifically focused on detecting the modification of variables such as the family quotient (Q-CAF) and period of billing, which can be modified to change
