“…Similar visualizations of named entity data have been used in, e.g., DBpedia Spotlight 17 [26] and Gate Cloud 18 [25]. The WarSampo [13] portal and the Semantic Finlex portal [29] include contextual reader applications that have been configured to link text into ontologies in real-time. These applications have influenced the creation of the BiographySampo's contextual reader.…”

“…For place linking, we used the YSO Places ontology 13 of the Finnish Ontology Service Finto that contains contemporary place resources for municipalities, provinces, countries, and continents. The contemporary data was extended with the WarSampo place ontology [13] that includes historical Finnish places. A priority order was set for place and person entities so that more specific place names, for instance, have a higher score.…”

“…There are currently only three types of named entities visible in the contextual reader to provide context but more could be added, such as named works of art. Also, it would be useful to add a map or images for places as has been done in [29,13]. The extracted named entities from the texts are often people that the authors of the biographies consider significant occupationally.…”

This paper shows how named entity extraction and network analysis can be used to examine biographies individually and in groups to aid historians in biographical and prosopographical research. For this purpose a reference network of 13100 biography entries in the collections of the Biographical Centre of the Finnish Literature Society was created, based on links between the biographies as well as automatically extracted named entities found in the texts. The data was published in a SPARQL endpoint as a Linked Data knowledge graph on top of which network analytic tools were created and analysis were done showing the usefulness of the approach in Digital Humanities. The reference graph has been utilized for network analysis to examine egocentric networks of individual persons as well as networks among groups of people in prosopography. The data and tools presented are in use in the new national semantic portal BiographySampo published in the autumn of 2018.

“…The underlying data is not available in machine-readable, i.e., "semantic" form for Digital Humanities research and use [5,3] and for end-user applications to utilize. By making war data more accessible our understanding of the reality of the war improves, which not only advances understanding of the past but also hopefully promotes peace in the future [7].…”

Abstract. War history of the Second World War (WW2), humankind's largest disaster, is of great interest to both laymen and researchers. Most of us have ancestors and relatives who participated in the war, and in the worst case got killed. Researchers are eager to find out what actually happened then, and even more importantly why, so that future wars could perhaps be prevented. The darkest data of war history are casualty records-from such data we could perhaps learn most about the war. This paper presents a model and system for representing death records as linked data, so that 1) citizens could find out more easily what happened to their relatives during WW2 and 2) digital humanities (DH) researchers could (re)use the data easily for research.

“…Kansa Taisteli magazine articles can be searched and explored in the WarSampo portal, which models the Second World War in Finland as Linked Open Data (LOD). [13] Kansa Taisteli is a magazine published by Sanoma Ltd and Sotamuisto association between 1957 and 1986. [24] The magazine articles cover the memoirs of WW2 from the point of view of Finnish military personnel and civilians.…”

This paper presents an automatic annotation tool AATOS for providing documents with semantic annotations. The tool links entities found from the texts to ontologies defined by the user. The application is highly configurable and can be used with different natural language Finnish texts. The application was developed as a part of the WarSampo 1 and Semantic Finlex 2 projects and tested using Kansa Taisteli magazine articles and consolidated Finnish legislation of Semantic Finlex. The quality of the automatic annotation was evaluated by measuring precision and recall against existing manual annotations. The results showed that the quality of the input text, as well as the selection and configuration of the ontologies impacted the results.
