BL-Viz4D: A Digital Twin viewer for Maintenance
BL-VIZ4D is a research project led by Berger-Levrault, dedicated to the visualization, synchronization, and interaction with digital twins applied to maintenance. Stemming from thesis work conducted in partnership with the LIRIS laboratory (Laboratory of Image Informatics and Information Systems), BL-VIZ4D explores the scientific and technological foundations of a multi-scale 3D viewer capable of aggregating heterogeneous geospatial data—attribute, 2D, and 3D—and linking it to CMMS business processes. The viewer allows for

Not all Hallucinations are Good to Throw Away When it Comes to Legal Abstractive Summarization
The extensive use of Large Language Models (LLMs) for summarization tasks brings new challenges. One of the most important is related to the LLMs’ tendency to generate hallucinations, i.e., texts that give the impression of being fluid and natural, despite their lack of fidelity and nonsensical nature. Hallucinations can be factual: a source of knowledge,

Extracting services from legacy software system
Let’s explore together the recent poster created by Soufyane Labsari and published about extracting services from legacy software systems. This work is done in collaboration with Inria.

Improved comment generation by LLMs
In the world of programming, creating efficient and functional software is a top priority, but it’s not just about writing lines of code. An essential part of the software development process is documentation, which includes the creation of explanatory comments that help to understand the operation and logic of the source code. However, writing these

Federated Learning, the security asset for local maintenance of your data
Predictive maintenance, coupled with the Internet of Things (IoT) and Artificial Intelligence (AI), represents a revolutionary approach to equipment maintenance. Traditionally, maintenance has been performed on a fixed schedule or in response to failures, leading to inefficiencies and downtime. Predictive maintenance aims to address these shortcomings by leveraging IoT sensors and AI algorithms to predict

Information extraction from Berger-Levrault books and articles
Historically, Berger-Levrault has been a publisher of legal and practical books and articles. The articles are on line and come from Légibases. Exploiting the knowledge contained in these texts is difficult. This is why it is necessary to structure the knowledge so that it can be accessed quickly. Berger-Levrault develops software solutions specialized in Automatic

A Modest first step in Test Generation
In the field of software development, code testing is a paramount task that should never be overlooked. At Berger-Levrault, we take this responsibility seriously and enforce a strict policy that includes the establishment of continuous integration (CI) and quality gates in our SonarQube server. Testing not only supports various developer activities, but also serves as

Classification of business documents to aid extraction: the use of typed and weighted lexical-semantic relations
I’ve been a member of the Berger-Levrault research team since 2020. I’m working on a CIFRE thesis on methods and models for the automated construction of multi-domain ontology databases, in collaboration with the Montpellier Laboratory of Computer Science, Robotics and Microelectronics (LIRMM). This work was presented at the PFIA (Plate-forme Intelligence Artificielle) 2023 in Strasbourg

Integrate Software Engineering into the everyday world
I have been a member of the Berger-Levrault research team for 6 years. And, one of our main challenges is integrating our innovation into the day-to-day world of the company. There are several ways to incorporate innovation: as an external code library, providing schema, teaching how to use new tools, and so on. In this
