These data are typically heterogeneous datasets where communication networks between people and the times and geographical locations they take place are important aspects. We argue that these features make the area of temporal communications a promising application case for Linked Data (LD)-based methods combined with temporal network analyses. The key result of this paper is to present a framework, tools, and systems for creating, publishing, and analyzing historical LD from a network science perspective. The focus is on network analysis of epistolary network data (metadata about letters), based on recent advances in analysis of temporal communication networks and the behavioural patterns commonly found in them. To test, evaluate, and demonstrate the usability of the framework, this paper shows how network analysis has been applied to (1) the Dutch CKCC corpus (of ca. 20,000 letters), (2) the pan-European correspSearch corpus (of ca. 135,000 letters) with promising results. The tools presented have also been re-used successfully in other related systems, such as LetterSampo Finland (1809\u20131917) of 1.2 million historical letters.<\/jats:p>","DOI":"10.1177\/22104968261452976","type":"journal-article","created":{"date-parts":[[2026,6,6]],"date-time":"2026-06-06T11:32:31Z","timestamp":1780745551000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Knowledge Graphs and Data Services for Studying Historical Epistolary Data in Network Science on the Semantic Web"],"prefix":"10.1177","volume":"17","author":[{"given":"Petri","family":"Leskinen","sequence":"first","affiliation":[{"name":"Aalto University"},{"name":"HELDIG \u2013 Helsinki Centre for Digital Humanities, University of Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier","family":"Ure\u00f1a-Carrion","sequence":"additional","affiliation":[{"name":"Aalto University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4789-5676","authenticated-orcid":false,"given":"Jouni","family":"Tuominen","sequence":"additional","affiliation":[{"name":"Aalto University"},{"name":"HELDIG \u2013 Helsinki Centre for Digital Humanities, University of Helsinki, Finland"},{"name":"HSSH \u2013 Helsinki Institute for Social Sciences and Humanities, University of Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mikko","family":"Kivel\u00e4","sequence":"additional","affiliation":[{"name":"Aalto University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eero","family":"Hyv\u00f6nen","sequence":"additional","affiliation":[{"name":"Aalto University"},{"name":"HELDIG \u2013 Helsinki Centre for Digital Humanities, University of Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,6,6]]},"reference":[{"key":"e_1_3_4_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/asi.24984"},{"issue":"2","key":"e_1_3_4_3_1","first-page":"359","article-title":"Applying and developing semantic web technologies for exploiting a corpus in history of science: The case study of the Henri Poincar\u00e8 correspondence","volume":"12","author":"Bruneau O.","year":"2021","unstructured":"Bruneau O., Lasolle N., Lieber J., Nauer E., Pavlova S., Rollet L.
