The Finnish General Upper Ontology YSO

The aim of this part of the FinnONTO project is to build the Finnish General Upper Ontology YSO based on the widely used Finnish General Thesaurus maintained by The National Library of Finland. The idea is that The Finnish General Ontology with ca. 20 000 concepts could be “the semantic glue” between many domain ontologies and this way offer a possibility to link contents from different domains in the Finnish semantic web.

In the FinnONTO project The Finnish General Upper Ontology will be used for example in the health information portal TerveSuomi.fi and in the cultural heritage portal Kulttuurisampo.fi.

YSO-ontology can be used and integrated with a client application by using the ONKI Ontology Server.

Yleinen suomalainen ontologia (YSO)

Tämän FinnONTO-projektin osahankeen tavoitteena on kehittää laajassa käytössä olevan Kansalliskirjaston Yleisen suomalaisen asiasanaston (YSA) pohjalta Yleinen suomalainen ontologia (YSO). Ajatuksena on, että noin 20 000 käsitteestä koostuva YSO voisi muodostaa "semanttisen liiman" eri alakohtaisten ontologioiden välillä ja näin tarjota mahdollisuuksia yhdistää eri alojen sisältöjä suomalaisessa semanttisessa webissä.

YSO:a sovelletaan FinnONTO-projektissa esimerkiksi terveyden edistämisen TerveSuomi.fi-portaalissa ja kulttuurialan Kulttuurisampo-portaalissa.

YSO-ontologia on käytettävissä ja kytkettävissä asiakassovellusten osaksi ONKI-ontologiapalvelimen avulla.

Tomi Kauppinen, Heini Kuittinen, Jouni Tuominen, Katri Seppälä and Eero Hyvönen: Extending an Ontology by Analyzing Annotation Co-occurrences in a Semantic Cultural Heritage Portal. Proceedings of the ASWC 2008 Workshop on Collective Intelligence (ASWC-CI 2008) organized as a part of the 3rd Asian Semantic Web Conference (ASWC 2008), Bangkok, Thailand, February 2-5, 2009. bib pdf
Ontologies aim to capture knowledge about things and their relationships. Publishing ontologies on the Semantic Web enables people and organizations to use shared ontologies in annotating e.g. photographs, videos, music, and other types of cultural objects. Search engines also use relationships provided by ontologies in semantic search, e.g. for query expansion or for view-based search. However, building ontologies is a time-consuming process, and it should be helped by automatic finding of interesting, possible relationships. Finding the correct concept for annotation purposes is helped by subsumption and partonomy hierarchies and associative relationships. In this paper we show how an analysis of co-occurrences of concepts in annotations can be used to provide interesting relationships for enriching ontological structures. We use association rule mining techniques and test the idea using a set of annotations of cultural objects in CULTURESAMPO portal and the Finnish General Upper Ontology YSO. The results are visualized in the ONKI SKOS browser to give an additional layer on top of the original relationships of the YSO ontology. An analysis shows that best ranked relationships should also be included in the ontology as subclassof or associative relationships.

Jussi Kurki and Eero Hyvönen: Relational Semantic Search: Searching Social Paths on the Semantic Web. Poster Proceedings of the International Semantic Web Conference (ISWC 2007), Busan, Korea, Nov, 2007. bib pdf
This paper presents a system for searching semantic relations between web resources, in our case significant persons of art history. The system is based on the Union List of Artists Names (ULAN) metadata of some 120,000 persons and organizations.
Eero Hyvönen, Robin Lindroos, Tomi Kauppinen and Riikka Henriksson: An ontology service for geographical content. Poster Proceedings of the International Semantic Web Conference (ISWC 2007), Busan, Korea, Nov, 2007. bib pdf
Geographic place names are widely used but are semantically often highly ambiguous. For example, there are 491 places in Finland sharing the same name Isosaari (great island) that are instances of several geographical classes, such as Island, Forest, Peninsula, Inhabited area, etc. Referencing unambiguously to a particular Isosaari , either when annotating content or during information retrieval, can be quite problematic and requires usage of advanced search methods and maps for semantic disambiguation. This paper presents an ontology server, ONKI-Paikka, for solving the place finding and place name disambiguation problem. In ONKI-Paikka, places can be found by a faceted search engine, combined with semantic autocompletion and a map service for constraining search and for visualizing results. The service can be connected to legacy applications cost-effectively by using Ajax-technology in the same spirit as Google Maps that is used in ONKI-Paikka as a subservice.
