Finnish Ontology Service of Historical Places and Maps

Historiallinen paikkatieto on keskeisessä asemassa muistiorganisaatioiden kokoelmien hallinnassa ja hyödyntämisessä sekä digitaalisten ihmistieteiden tutkimuksessa. Paikkatiedon käsitteleminen muissa kuin erikoistuneissa paikkatietojärjestelmissä sekä paikkatiedon ajallinen ulottuvuus tuovat mukanaan lukuisia haasteita, joihin linkitetyn datan teknologiat ovat tarjonneet lupaavia ratkaisuja. Tässä työssä esitellään kulttuurialan organisaatioiden tarpeeseen kehitetty uusi linkitetyn datan teknologioihin perustuva historiallisten paikkojen ja karttojen palvelumalli, HIPLA. HIPLA-palvelumallin tavoitteena on tarjota yhteinen näkymä eri organisaatioiden hallinnoimaan paikkatietoon ja mahdollistaa hajautettujen paikkatietoaineistojen yhteisöllinen täydentäminen, haku ja selailu sekä nykyisillä että historiallisilla kartoilla. Lisäksi työssä toteutettiin HIPLA-palvelumallin etuja havainnollistava prototyyppisovellus Hipla.fi, jota pilotoitiin osana talvi- ja jatkosodan aineistoja linkitettynä avoimena datana julkaisevaa Sotasampo-projektia. Pilotoinnin tuloksena syntyi talvi- ja jatkosodan paikkaontologia, joka tarjoaa työkalun sotiin liittyvien aineistojen automaattiselle linkitykselle ja aineistojen maantieteelliselle visualisoimiselle.Historical geographic data plays an important part in the management of cultural heritage data and also in digital humanities research. This brings forth problems such as managing the spatial dimension of geographic data, and the fact that traditionally geospatial data has been isolated in geographic information systems. Linked data technologies are a promising approach to these problems. This thesis presents a new Linked Open Data brokering service model HIPLA for using and maintaining distributed historical place gazetteers and maps. HIPLA provides a common access to historical geographic data and facilitates collaborative maintenance of geo-ontologies and maps in real time as a side effect of annotating contents in legacy cataloging systems. Hipla.fi, the first prototype implementation of the HIPLA model, was created to test and demonstrate the HIPLA model. The Hipla.fi user interface and data service were also applied in creating a semantic portal of historical Second World War data

Sampo-UI: A Full Stack JavaScript Framework for Developing Semantic Portal User Interfaces

This paper presents a new software framework, SAMPO-UI, for developing user interfaces for semantic portals. The goal is to provide the end-user with multiple application perspectives to Linked Data knowledge graphs, and a two-step usage cycle based on faceted search combined with ready-to-use tooling for data analysis. For the software developer, the SAMPO-UI framework makes it possible to create highly customizable, user-friendly, and responsive user interfaces using current state-of-the-art JavaScript libraries and data from SPARQL endpoints, while saving substantial coding effort. SAMPO-UI is published on GitHub under the open MIT License and has been utilized in several internal and external projects. The framework has been used thus far in creating six published and five forth-coming portals, mostly related to the Cultural Heritage domain, that have had tens of thousands of end-users on the Web.Peer reviewe

WarVictimSampo 1914–1922: a National War Memorial on the Semantic Web for Digital Humanities Research and Applications

AcceptedThis article presents the semantic portal and Linked Open Data service WARVICTIMSAMPO 1914-1922 about the war victims, battles, and prisoner camps in the Finnish Civil and other wars in 1914-1922. The system is based on a database of the National Archives of Finland and additional related data created, compiled, and linked during the project. The system contains detailed information about some 40,000 deaths extracted from several data sources and data about over 1,000 battles of the Civil War. A key novelty of WARVICTIMSAMPO 1914-1922 is the integration of ready-to-use Digital Humanities visualizations and data analysis tooling with semantic faceted search and data exploration, which allows, e.g., studying data about wider prosopographical groups in addition to individual war victims. The article focuses on demonstrating how the tools of the portal, as well as the underlying SPARQL endpoint openly available on the Web, can be used to explore and analyze war history in flexible and visual ways. WARVICTIMSAMPO 1914-1922 is a new member in the series of "Sampo" model-based semantic portals. The portal is in use and has had 23,000 users, including both war historians and the general public seeking information about their deceased relatives.Peer reviewe

WarVictimSampo 1914–1922: A Semantic Portal and Linked Data Service for Digital Humanities Research on War History

This paper presents the semantic portal and Linked Open Data (LOD) service WarVictimSampo 1914–22 about the war victims, battles, and prisoner camps in the Finnish Civil and other wars. The system is based on a database of the National Archives of Finland and related data compiled during the project. The system contains detailed information about some 40 000 deaths extracted from several data sources, and data about prisoner camps and over 1000 battles of the Civil War. A key novelty of WarVictimSampo 1914–22 is the integration of ready-to-use Digital Humanities tooling with the data service, which allows, e.g., studying information about wider prosopographical groups in addition to individual victims. We demonstrate how the tools of the portal, as well as the underlying SPARQL endpoint, can be used to explore and analyze war history in flexible and visual ways. WarVictimSampo 1914–22 is a new member in the series of “Sampo” model based semantic portals. It was published in late 2019 and got 20 000 users in two weeks.Peer reviewe

WarMemoirSampo : A Semantic Portal for War Veteran Interview Videos

Publisher Copyright: © 2022 Copyright for this paper by its authors. Use permitted under Creative Commons License Attribution 4.0 International (CC BY 4.0)This paper presents WarMemoirSampo, a portal that provides semantic search and navigation of video interviews with Finnish World War II veterans. The portal associates video fragments with contextual data extracted from the video transcriptions, enabling users to find suitable video segments via faceted search and highlighting relevant content in the video being watched. This is carried out by processing natural language texts in order to extract named entities, keywords and lemmas. The result is a Linked Data Knowledge Graph that underpins the portal. We describe the collaboration between Natural Language Processing and Semantic Web technologies used in order to produce these results.Peer reviewe
