Horizon 2020 and Horizon Europe are key EU initiatives fostering collaborative research and innovation across Europe. The data about Horizon programmes can be explored via the CORDIS Data Lab at https://cordis.europa.eu/datalab/  and can be accessed trough https://data.europa.eu/data/datasets/cordish2020projects for Horizon 2020 and https://data.europa.eu/data/datasets/cordis-eu-research-projects-under-horizon-europe-2021-2027 
for Horizon Europe..

The Horizon projects network dataset is a collection of case studies created with the Horizon intelligence software [DOI: 10.5281/zenodo.11276687]. Its purpose is to provide an additional method for analyzing the impact of Horizon projects, specifically in terms of collaborations among European organizations, leveraging network analysis and community detection techniques. The dataset has been enriched with NUTS3 geolocation data and name tags for Italian organizations and is segmented by year, covering the period from 2015 to 2029.

The dataset includes 3 case studies, each focused on a specific topic, selected using the EuroSciVoc taxonomy: hydrogen energy, electron microscopy, and pandemics. For each case study, the dataset includes:

• A set of CSV files:

  • O.csv: Contains organisation unique identifier and attributes.
  • P.csv: Contains project unique identifier and attributes.
  • W.csv: Describes the participation of each organization in a project for each specific year. The participation is weighted according to the "total cost" of the project, shared proportionally based on the project's duration within that year.

• An additional CSV file, activity_type.csv, which provides a description of the codes used to define the activity types associated with each organization.

• A set of network files representing the collaboration between organizations in any given year (from 2015 to 2029), in interoperable format .graphML. These yearly graphs include centrality measures (degree, strength, coreness) and community labels. More details on .graphMLformat are provided in format-info.txt file.
