BookSampo - Semantic Portal for Finnish Fiction Literature

What is BookSampo?

BookSampo is a semantic portal in use, covering metadata about practically all Finnish fiction literature of Finnish public libraries on a work level. The system introduces a variety of semantic web novelties deployed into practise: The underlying data model is based on the emerging functional, content-centered metadata indexing paradigm using RDF. Linked Data (LD) principles are used for mapping the metadata with tens of interlinked ontologies in the national FinnONTO ontology infrastructure. The contents are also linked with the large LD metadata repository of related cultural heritage content of CultureSampo. BookSampo is actually based on using CultureSampo as a semantic web service, demonstrating the idea of re-using semantic content from multiple perspectives without the need for modifications.

Public Portal On the Web

The portal has been online since autumn 2011 at: http://www.kirjasampo.fi/.

The BookSampo portal interface application was implemented by the Finnish public library consortium Kirjastot.fi. The system is based on the fiction literature ontology KAUNO (developed from the Kaunokki thesaurus) and other ontologies developed in the FinnONTO-project, and metadata from library databases, biographies, review articels, and other sources. The contents, search, and recommending services of the portal come through the APIs of the CultureSampo system, that contains all semantic content of the system interlinked in RDF with other cultural materials.

Collaborative Content Creation

Most of the BookSampo content has been transformed automatically from existing databases, with the help of ontologies derived from thesauri in use in Finland, but in addtion tens of volunteered librarians have participated in a Web 2.0 fashion in annotating and correcting the metadata using the SAHA metadata editor connected to the ONKI ontology services of FinnONTO, especially regarding older litarature.

The paper focuses on lessons learned in the process of creating the semantic web basis of BookSampo.

Tiivistelmä suomeksi

Kirjasampo on semanttisen webin teknologiaa hyödyntävä portaali. Se perustuu Aalto- ja Helsingin yliopiston Semanttisen laskennan tutkimusryhmän (SeCo) johtamassa kansallisessa FinnONTO-hankkeessa (2003-2012) kehitettyyn teknologiaan, menetelmiin ja julkaisukonsepteihin. Hankkeen rahoittivat Tekes ja n. 40 organisaation konsortio, mukaan lukien Kirjastot.fi (Helsingin kaupunginkirjasto - Yleisten kirjastojen keskuskirjasto).

Järjestelmän sisällön ydinaines on peräisen Helmet-tietokannasta, joka muunnettiin semanttisen webin RDF-muotoon. Tämän jälkeen aineistoa rikastettiin, erityisesti vanhempien teosten osalta, kymmenien vapaaehtoisen kirjastonhoitajien toimesta käyttämällä hyväksi SAHA-metadataeditoria ja kansallisen ONKI-ontologiakirjaston ontologioita. Aineisto sillattiin Linked Data -periaatteiden mukaisesti osaksi laajaa Kulttuurisampo-järjestelmää, joka sisältää satoja tuhansia erilaisia suomalaisia kulttuurikohteita toisiinsa yhdistettynä, nyt mukaan lukien suomalainen kertomakirjallisuus teostasolla.

Kirjasammon aineisto ja palvelut perustuvat Kulttuurisammmon tarjoamiin semanttisiin palveluihin, joita Kirjasampo käyttää rahapintojensa kautta. Kirjasammon käyttöliittymä on suunniteltu ja toteutettu Kirjastot.fi-yhteisön toimesta itsenäisesti omana hankkeenaan.

Lisätietoja ja tutkimusartikkeleita Kirjasammon taustalla olevasta työstä löytyy hankkeen tutkimussivulta.
