This paper presents a new knowledge-based approach for finding serendipitous semantic relations between resources in a knowledge graph. The idea is to characterize the notion of “interesting connection” in terms of generic ontological explanation patterns that are applied to an underlying linked data repository to instantiate connections. In this way, 1) semantically uninteresting connections can be ruled out effectively, and 2) natural language explanations about the connections can be created for the end-user. The idea has been implemented and tested based on a knowledge graph of biographical data extracted from the life stories of 13,144 prominent historical persons in Finland, enriched by data linking to collection databases of museums, libraries, and archives. The demonstrator is in use as part of the BiographySampo portal of interlinked biographies.

This paper introduces AMMO Ontology of Finnish Historical Occupations. AMMO is based on thousands of occupation labels extracted from three Finnish military historical datasets of the early 20th century: the first consists of the ca. 40 000 war-related death records around the time of the Finnish Civil War (1914–1922); the second consists of the ca. 95 000 death records of Finnish soldiers in the Winter War and Continuation War (1939–1944); the third contains the ca. 4500 records of Finnish prisoners of war in the Soviet Union during the WW2. Our goal from a Digital Humanities perspective is to use AMMO to study military history and these datasets based on the occupation and social status of the soldiers. AMMO will also be used as a component for faceted search and semantic recommendation in two semantic portals for Finnish military history. AMMO is aligned with the international historical occupation classification HISCO and with a modern Finnish occupational classification for international and national interoperability. The ontology is published as Linked Open Data in an ontology service.

Historical datasets often impose the need to study groups of people based on occupation or social status. This paper presents first results in creating an ontology of historical Finnish occupations, AMMO, that enables selection of groups of people based on their occupation, occupational groups, or socioeconomic class. AMMO is linked to the international historical occupation classification HISCO and to a modern Finnish occupational classification for interoperability. AMMO will be used as a component in two semantic portals for Finnish war history.

Heikki Rantala: Yhteyshaku semanttisessa webissä. MSc Thesis (in Finnish), University of Helsinki, Department of Computer Science, January, 2019. bib pdf
Tavallisessa haussa etsitään yksilöitä, kuten henkilöitä tai paikkoja. Joissain tilanteissa esimerkiksi historian tutkija voi olla kiinnostunut myös etsimään yhteyksiä henkilöiden ja paikkojen välillä. Tässä työssä esitetään metodi tällaisen yhteyshaun toteuttamiseksi käyttäen semanttisen webin sisältämää avointa dataa. Työssä muodostettiin graafi, joka sisältää kuvauksia Suomen kulttuu- rihistorian henkilöiden ja paikkojen välisistä kiinnostaviksi arvioiduista yhteyksistä. Graafi luotiin SPARQL CONSTRUCT -kyselyillä. Yhteyksien hakemista varten luotiin web-sovellus, joka hyödyntää fasettihakua. Tarvittavien SPARQL CONSTRUCT -kyselyjen luominen ei osoittautunut erityisen hankalaksi, mutta niiden soveltaminen yleisemmin eri aineistoihin vaatii jonkin verran työtä. Yhteyksien fasettihaku osoittautui mielenkiintoiseksi. Fasettihaku mahdollistaa haun tarkentamisen askel kerrallaan. Lisäksi yhteyksien suhteellisia määriä on mahdollista vertailla erilaisten rajausten mukaan. Tämä tarjoaa aineistoon uusia näkökulmia.

Biografiasampo-järjestelmä käynnistää uuden aikakauden elämäkertakokoelmien julkaisemisessa ja käyttämisessä verkossa. Järjestelmän ydinaineistona on Kansallisbiografia ja muut Suomalaisen Kirjallisuuden Seuran (SKS) ja tieteellisten seurojen toimittamat pienoiselämäkerrat, yhteensä 13 100 elämäntarinaa, joita on kirjoittanut 900 suomalaista tutkijaa. Biografiasammon innovaationa on luoda kieliteknologian, tekoälyn ja semanttisen webin teknologioiden avulla elämäkertojen teksteistä ja niihin eri lähteissä liittyvistä tiedoista tietämysverkko (knowledge graph) ja kansallinen tietoinfrastruktuuri, joka koostuu miljoonista tietojen välisistä yhteyksistä. Tietämysverkko on julkaistu linkitetyn datan palvelussa, jonka varaan on toteutettu seitsemästä sovellusnäkymästä koostuva älykäs, kaikille avoin ja maksuton verkkopalvelu biografiasampo.fi kansalaisten ja digitaalisten ihmistieteiden tutkijoiden käytettäväksi.
