Résumé du contexte et des objectifs généraux du projet

SciLake is a Horizon Europe project that leverages Scientific Knowledge Graphs (SKGs) to establish the concept of the Scientific Lake: an interoperable ecosystem for the creation, integration, enrichment, management, and exploitation of scholarly knowledge. The project addresses key challenges faced by the European research ecosystem, including the fragmentation of scholarly information, limited interoperability among research infrastructures, difficulties in assessing research impact and reproducibility, and barriers to cross-disciplinary knowledge discovery.
In alignment with the objectives of the European Open Science Cloud (EOSC), SciLake promotes open, interoperable, and reusable research infrastructures. Its objectives were to: (i) overcome the heterogeneity of scholarly content, (ii) democratise the creation and use of SKGs, (iii) facilitate the identification of research trends and valuable research outputs, (iv) support reproducibility assessment, (v) validate the developed services in real-world pilots, and (vi) contribute to the EOSC ecosystem through standards and reusable assets.
The project delivered a two-tier ecosystem consisting of the Scientific Lake infrastructure and a set of value-added applications for impact-driven scientific knowledge discovery and reproducibility assistance. Its technologies were deployed and validated through five pilot-specific SKGs covering Cancer, Neuroscience, Energy, Transport-CCAM, and Transport-Maritime research, demonstrating their applicability across diverse scientific communities.

Travail effectué depuis le début du projet jusqu’à la fin de la période considérée dans le rapport et principaux résultats atteints jusqu’à présent

SciLake designed, developed, integrated, and validated a complete ecosystem for the creation and exploitation of Scientific Knowledge Graphs. A major achievement was the delivery of the Scientific Lake service, a suite of interoperable components supporting data acquisition, knowledge graph creation, graph interlinking, multilingual processing, graph analytics, querying, and unified access to heterogeneous scholarly knowledge.
The project contributed to the Scientific Knowledge Graph Interoperability Framework (SKG-IF) and delivered the Lake API, providing a common interoperability and access layer across multiple scientific knowledge graphs. Significant advances were achieved in graph generation and profiling, entity resolution, graph analytics, large-scale graph processing, impact assessment, topic analysis, research artefact identification, citation-context analysis, and reproducibility assessment.
Building on this infrastructure, SciLake delivered two advanced applications: the Smart Impact-driven Discovery Service and the Smart Reproducibility Assistance Service. These services support the identification of influential research outputs, emerging trends, reproducibility signals, and relationships among publications, datasets, software, and other research artefacts.
The project deployed and evaluated five pilot-specific Scientific Knowledge Graphs covering Cancer, Neuroscience, Energy, Transport-CCAM, and Transport-Maritime research. The outcomes include five reusable SKG datasets, a portfolio of software components and services, the Lake API, contributions to SKG-IF, the two value-added applications, and 19 scientific publications (6 journal articles, 12 conference/workshop papers, and 1 magazine contribution).

Progrès au-delà de l’état des connaissances et impact potentiel prévu (y compris l’impact socio-économique et les conséquences sociétales plus larges du projet jusqu’à présent)

SciLake delivered a comprehensive set of scientific, technical, and infrastructure results centred on interoperable Scientific Knowledge Graphs. Key outcomes include the Scientific Lake service, the Smart Impact-driven Discovery Service, the Smart Reproducibility Assistance Service, the Lake API, five domain-specific SKGs, contributions to SKG-IF, and a portfolio of reusable software, datasets, and publications.
The project generated advances in knowledge graph creation, graph analytics, graph query optimisation, entity resolution, large-scale graph processing, impact assessment, and reproducibility analysis. Novel results include field-normalised impact indicators, indicators for datasets and software, topic-evolution analytics, research artefact recognition, citation-context analysis, and reproducibility indicators.
Beyond its technical contributions, SciLake strengthened the open science and EOSC landscape through interoperable datasets, open-source software, reusable services, and contributions to emerging interoperability standards. The project produced 5 SKG datasets and 19 scientific publications.
To maximise long-term impact, further efforts should focus on adoption by research infrastructures, EOSC initiatives, and scientific communities. Key needs include the sustained operation of the developed services and datasets, continued evolution of SKG-IF, integration with EOSC infrastructures, and follow-up initiatives building on the project’s exploitable results. The exploitation strategy developed with support from the Horizon Results Booster identified concrete pathways for sustaining and further developing the project’s key assets.
