Furthermore, the content is usually available only for humans to read, and not as data for Digital Humanities (DH) analyses and application development. This application report addresses these problems by presenting a collaborative publication model for CH Linked Data and six design principles for creating shared data services and semantic portals for DH research and applications. This Sampo model has evolved gradually in 2002\u20132021 through lessons learned when developing the Sampo series of linked data services and semantic portals in use, including MuseumFinland (2004), CultureSampo (2009), BookSampo (2011), WarSampo (2015), Norssit Alumni (2017), U.S. Congress Prosopographer (2018), NameSampo (2019), BiographySampo (2019), WarVictimSampo 1914\u20131922 (2019), MMM (2020), AcademySampo (2021), FindSampo (2021), WarMemoirSampo (2021), and LetterSampo (2022). These Semantic Web applications surveyed in this paper cover a wide range of application domains in CH and have attracted up to millions of users on the Semantic Web, suggesting feasibility of the proposed Sampo model. This work shows a shift of focus in research on CH semantic portals from data aggregation and exploration systems (1. generation systems) to systems supporting DH research (2. generation systems) with data analytic tools, and finally to automatic knowledge discovery and Artificial Intelligence (3. generation systems).<\/jats:p>","DOI":"10.3233\/sw-223034","type":"journal-article","created":{"date-parts":[[2022,8,30]],"date-time":"2022-08-30T12:10:44Z","timestamp":1661861444000},"page":"729-744","source":"Crossref","is-referenced-by-count":36,"title":["Digital humanities on the Semantic Web: Sampo model and portal series"],"prefix":"10.1177","volume":"14","author":[{"given":"Eero","family":"Hyv\u00f6nen","sequence":"first","affiliation":[{"name":"Department of Computer Science, Aalto University, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/SW-223034_ref1","doi-asserted-by":"publisher","first-page":"879","DOI":"10.1007\/978-3-540-76298-0_64","volume-title":"CHIP Demonstrator: Semantics-Driven Recommendations and Museum Tour Generation, in: The Semantic Web","author":"Aroyo","year":"2007"},{"issue":"5","key":"10.3233\/SW-223034_ref2","first-page":"34","volume":"284","author":"Berners-Lee","year":"2001","journal-title":"The Semantic Web, Scientific American"},{"key":"10.3233\/SW-223034_ref3","doi-asserted-by":"publisher","DOI":"10.3233\/SW-210425"},{"key":"10.3233\/SW-223034_ref5","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-030-30796-7_3"},{"key":"10.3233\/SW-223034_ref6","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9781139003865"},{"issue":"3","key":"10.3233\/SW-223034_ref7","doi-asserted-by":"publisher","first-page":"96","DOI":"10.1145\/3418294","article-title":"Knowledge graphs","volume":"64","author":"Gutierrez","year":"2021","journal-title":"Communications of the ACM"},{"issue":"2","key":"10.3233\/SW-223034_ref8","doi-asserted-by":"publisher","first-page":"117","DOI":"10.1177\/0165551515594729","article-title":"Current state of linked data in digital libraries","volume":"42","author":"Hallo","year":"2016","journal-title":"Journal of Information Science"},{"key":"10.3233\/SW-223034_ref10","unstructured":"M.\u00a0Hearst, Design recommendations for hierarchical faceted search interfaces, in: ACM SIGIR Workshop on Faceted Search, Seattle, WA, 2006, pp.\u00a01\u20135."},{"key":"10.3233\/SW-223034_ref11","doi-asserted-by":"publisher","DOI":"10.2200\/S00334ED1V01Y201102WBE001"},{"key":"10.3233\/SW-223034_ref12","unstructured":"F.\u00a0Hern\u00e1ndez, L.\u00a0Rodrigo, J.\u00a0Contreras and F.\u00a0Carbone, Building a cultural heritage ontology for Cantabria, in: Annual Conference of CIDOC, 2008, pp.\u00a01\u201314, https:\/\/cidoc.mini.icom.museum\/wp-content\/uploads\/sites\/6\/2018\/12\/64_papers.pdf."},{"issue":"2","key":"10.3233\/SW-223034_ref13","doi-asserted-by":"publisher","first-page":"76","DOI":"10.1145\/3397512","article-title":"A review of the semantic web field","volume":"64","author":"Hitzler","year":"2021","journal-title":"Commun.
