« The SPARQL query language is the standard method to access knowledge graphs (KGs). However, formulating SPARQL queries is a significant challenge for non-expert users, and remains time-consuming for the experienced ones. Best practices recommend to document KGs with competency questions and example queries to contextualise the knowledge they contain and…
« (…) In this paper, we present Q²Forge that addresses the challenge of generating new competency questions for a KG and corresponding SPARQL queries. It iteratively validates those queries with human feedback and LLM as a judge. Q²Forge is open source, generic, extensible and modular, meaning that the different modules of…
« From 13 to 14 March 2025, the OSTrails consortium convened in Athens for its first General Assembly—a key milestone that marked OSTrails’ transition from early development to integrated implementation and broader adoption. (…)

« OPERAS hosted the launch of the GRAPHIA project in Brussels earlier this year. On the 22nd and 23rd January, 2025, 21 partner institutions met in OPERAS’ office and online to celebrate the project which is funded by the European Commission for over €8 million, plus an additional €1.6 million from…
« In recent years, research integrity issues are in the limelight with the emergence of new and complex threats, such as paper mills, citation cartels, fabricated peer reviews, fake papers, artificial intelligence–generated images, among many others.1-4 A worrying feature of these emerging research integrity threats is that they often occur at…
« The current generation of artificial intelligence technologies, such as smart search engines, recommendation systems, tools for systematic reviews, and question-answering applications, plays a crucial role in helping researchers manage and interpret scientific literature. Taxonomies and ontologies of research topics are a fundamental part of this environment as they allow intelligent…
« Open Science has revolutionized scholarly communication and research assessment by introducing research data and software as first-class citizens. Scholarly Knowledge Graphs (SKGs) are expected to play a crucial role in generating research assessment indicators being able to aggregate bibliographic metadata records and semantic relationships describing all research products and their…
« (…) The paper aimed to provide a case study of how machine actionable DMPs can be contextualised and exploited in an Open Science Graph, and specifically the OpenAIRE Research Graph. ARGOS, the OpenAIRE DMP service, contributed to this work by paving the way to exposing ma-DMPs in OpenAIRE.

« The digital support for scientific reasoning presents contrasting results. Bibliometric services are improving, but not academic assessment; no service for scholars relies on logs of web usage to base query strategies for relevance judgments (or assessor shifts). Our Scientific Knowledge Graph GRAPHYP innovates with interpretable patterns of web usage, providing…
« La sélection d’articles publiés dans le présent recueil constitue les actes de la 23e édition de la conférence francophone sur l’Extraction et la Gestion des Connaissances (EGC 2023) qui s’est déroulée à l’Université Lumière Lyon 2, du 16 au 20 janvier 2023.
