However, this potential can be frustrated if these data remain unused. Although the literature suggests that OGD data sets\u2019 metadata quality is one of the main factors affecting their use, to the best of our knowledge, no quantitative study provided evidence of this relationship. Considering about 400,000 data sets of 28 national, municipal and international OGD portals, we have programmatically analysed their usage, their metadata quality and the relationship between the two. Our analysis has highlighted three main findings. First, regardless of their size, the software platform adopted, and their administrative and territorial coverage, most OGD data sets are underutilised. Second, OGD portals pay varying attention to the quality of their data sets\u2019 metadata. Third, we did not find clear evidence that data sets\u2019 usage is positively correlated to better metadata publishing practices. Finally, we have considered other factors, such as data sets\u2019 category, and some demographic characteristics of the OGD portals, and analysed their relationship with data sets\u2019 usage, obtaining partially affirmative answers.", "eprint" : "https://doi.org/10.1177/01655515211027775", "doi" : "10.1177/01655515211027775", "bibtexKey": "doi:10.1177/01655515211027775" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/25d791fe76a865e8a09b6764d3df16ed7/diglezakis", "tags" : [ "forschungsdaten","opendata","metadata","metrics","quality" ], "intraHash" : "5d791fe76a865e8a09b6764d3df16ed7", "interHash" : "3dd0f746b1beab1577af8e91c1fd452a", "label" : "Automated Quality Assessment of Metadata across Open Data Portals", "user" : "diglezakis", "description" : "", "date" : "2024-06-18 17:20:02", "changeDate" : "2024-06-18 17:20:02", "count" : 3, "pub-type": "article", "journal": "J.

More and more data\u2014from governments and public institutions but also from the private sector\u2014are made available online and are mainly published in so-called Open Data portals. However, with the increasing number of published resources, there is a number of concerns with regards to the quality of the data sources and the corresponding metadata, which compromise the searchability, discoverability, and usability of resources.In order to get a more complete picture of the severity of these issues, the present work aims at developing a generic metadata quality assessment framework for various Open Data portals: We treat data portals independently from the portal software frameworks by mapping the specific metadata of three widely used portal software frameworks (CKAN, Socrata, OpenDataSoft) to the standardized Data Catalog Vocabulary metadata schema. We subsequently define several quality metrics, which can be evaluated automatically and in an efficient manner. Finally, we report findings based on monitoring a set of over 260 Open Data portals with 1.1M datasets. This includes the discussion of general quality issues, for example, the retrievability of data, and the analysis of our specific quality metrics.", "numpages" : "29", "articleno" : "2", "issn" : "1936-1955", "issue_date" : "November 2016", "doi" : "10.1145/2964909", "bibtexKey": "10.1145/2964909" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2040f19393ccedf72d92ebc691c1ac2f5/diglezakis", "tags" : [ "opendata","metadata","quality" ], "intraHash" : "040f19393ccedf72d92ebc691c1ac2f5", "interHash" : "2b0220507b5e4051a4e609bdce0375b2", "label" : "Quality of Metadata in Open Data Portals", "user" : "diglezakis", "description" : "", "date" : "2024-06-18 15:45:22", "changeDate" : "2024-06-18 15:45:22", "count" : 1, "pub-type": "article", "journal": "IEEE Access", "year": "2021", "url": "", "author": [ "Javier Nogueras-Iso","Javier Lacasta","Manuel Antonio Ureña-Cámara","Francisco Javier Ariza-López" ], "authors": [ {"first" : "Javier", "last" : "Nogueras-Iso"}, {"first" : "Javier", "last" : "Lacasta"}, {"first" : "Manuel Antonio", "last" : "Ureña-Cámara"}, {"first" : "Francisco Javier", "last" : "Ariza-López"} ], "volume": "9","pages": "60364-60382", "doi" : "10.1109/ACCESS.2021.3073455", "bibtexKey": "9405650" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/27d1d2c377ce78645bbfe55118b36600f/diglezakis", "tags" : [ "forschungsdaten","opendata","metrics" ], "intraHash" : "7d1d2c377ce78645bbfe55118b36600f", "interHash" : "c4fad81fe4635f4ae380cbc4bee1b86b", "label" : "Open Data operationalisieren - Erfahrungen mit der Formulierung überprüfbarer Kriterien", "user" : "diglezakis", "description" : "Open Data operationalisieren - Erfahrungen mit der Formulierung überprüfbarer Kriterien | Zenodo", "date" : "2022-12-02 09:58:48", "changeDate" : "2022-12-02 08:58:48", "count" : 1, "pub-type": "presentation", "publisher":"Zenodo", "year": "2022", "url": "https://zenodo.org/record/7155925", "author": [ "Evgeny Bobrov" ], "authors": [ {"first" : "Evgeny", "last" : "Bobrov"} ], "copyright" : "Creative Commons Attribution 4.0 International", "language" : "de", "doi" : "10.5281/ZENODO.7155925", "bibtexKey": "https://doi.org/10.5281/zenodo.7155925" } ] }
