Dagoberto José Herrera Murillo started as an ESR on 15 March 2022 at the University of Zaragoza in Spain. In global terms, the research consists of designing user-driven UIs for finding data that fulfils different findability requirements from different domains. During this first year, Dagoberto has concentrated on identifying gaps between the needs of user groups and the current features of open data platforms. This has resulted in two lines of work: First, he has measured user involvement in open data portals in Europe and presented a paper entitled “Analysing User Involvement in Open Government Data Initiatives” at the International Conference on Theory and Practice of Digital Libraries in Padua, Italy. Second, he concludes that metadata quality issues are a major obstacle to designing better findability experiences. Dagoberto is also working on understanding the metadata model underlying the main government open data portals, DCAT. He is designing experiments where we improve the quality of sets present in data.europa.eu and then measure how this enriched metadata can enable the design of better search interfaces.

On 12 September 2022, Dagoberto started his secondment at the Spanish National Centre for Geographic Information in Madrid, Spain. His works consist of the user experience evaluation of a semantic search engine for geographic data products.
