Beyond Static Chunking: Multimodal and Adaptive Segmentation for Improved Information Retrieval
Introduction Retrieval-Augmented Generation systems [Li et al., 2025], called RAG, rely heavily on how documents are segmented before indexing. This preprocessing step, known as chunking, directly affects retrieval quality and, consequently, the performance of downstream question-answering systems. In practice, chunking strategies [Jain et al., 2025] hardly take into account the document structure; instead, documents are usually split into fixed-size segments without considering their semantic content or modality. Some more advanced
Migrating Katalon Studio Tests to Playwright with Model Driven Engineering
Introduction Migrating automated tests from one platform to another is a common challenge for software teams. In our recent project at Berger-Levrault, we tackled the migration of functional test cases from Katalon Studio to Playwright, aiming to minimize manual effort and maximize reliability. This post shares our semi-automated approach, key results, and lessons learned. Background:

When business-oriented software meets real life: what SEDIT teaches us
In our first article, we discussed the differences between “ideal scenarios” and actual work practices, and what these differences mean for the design of business-oriented software. In this second installment, we move from theory to practice: how did we measure these differences using SEDIT, an HRIS system from Berger-Levrault used in public administrations? The general
Usage discrepancies: when business software meets real life
Do users really follow the paths carefully mapped out by designers? And when reality goes beyond the scope of the design—which happens more often than we think—how can we know this other than through intuition and assumptions? On a daily basis, business-oriented software supports very concrete activities: managing leave, processing absences, tracking careers, producing regulatory
Gabriel Darbord Ph.D. thesis defense: “Automatic test generation to help modernize our applications”
Friday 5th December at 9a.m. Paris time, Gabriel Darbord, Ph.D. Candidate has defended his thesis named “Automatic test generation to help modernize our applications”. His thesis defense took place in Lille, France. Take a look at the summary below. This thesis is fully in line with the partnership between Berger-Levrault and Inria, which aims to
Enhancing Functional Testing Efficiency in Industrial Large-Scale Applications: Pertinent Test Selection
Introduction In modern software development, application reliability relies on effective testing strategies. Altough unit and integration tests secure internal consistency, functional testing remains essential for validating user-facing behaviors. For large-scale applications like Alpha Tool, running thousands of functional tests is challenging: it consumes vast resources, slows down delivery, and complicates analysis. This article explores the
Investigating Hand-Bound Pads for AR Input Using Hand-Tracking Only
What is Augmented Reality, and how is it used for Augmented Maintenance? Augmented Reality (AR) has emerged as a powerful tool for enhancing human-computer interaction, allowing digital content to be seamlessly integrated into the physical world. Unlike traditional desktop or mobile interfaces, AR enables spatially situated interactions, where virtual content is embedded within the user’s
Making Large Numbers Count: Cognitively Informed Alternatives to Log-Scale Bar Charts
From carbon emissions to national budgets, we’re frequently asked to interpret values that span from thousands to millions and billions. These wide ranges—what we call Orders of Magnitude Values (OMVs)—are cognitively demanding for the general public and hard to represent with common charts. So, how can we make sense of large numbers in order to
Explanation of the Coruscant Mobile project
This research is the result of a collaboration between Ali Can Kocabiyikoglu, Pascal Zaragoza, and Vincent Laval, part of the AI Laboratory | BL Research Team. The Challenge of Modern Maintenance Support A maintenance technician faces an unfamiliar “Error 20” on a medical device. Their hands are busy with tools, eyes on the equipment, yet

Sophie de Thoré guest on Pari ETI on BFM Business: Innovation, Growth and Digital Transformation
The digital transformation of public and private organisations, business resilience in the face of economic change, and responsible innovation were the focus of discussions on the Pari ETI programme broadcast on BFM Business. On this occasion, Sophie de Thoré spoke on behalf of Berger-Levrault, alongside Jérôme de Lavergnolle (Saint Louis), Jean-Luc Gunéard (LPR) and Augustin
A New Milestone in Building a European AI Ecosystem for Industry
Last Friday marked a significant step forward for the European ecosystem of artificial intelligence applied to industry. After more than a year of close collaboration, the report resulting from the Franco-German dialogue on industrial AI was officially presented to French and German authorities during a dedicated forum held at the Ministry of Economy. This initiative,
