The Finnish Law and Justice as a Linked Open Data Service
Work on this dataset is described in more detail on page
Semantic Finlex: Finnish Law and Justice on the Semantic Web
Our goal is to create a 7-star linked open data service of Finnish legislation, a semantic version of Finlex. Based on the service, a next generation of public and commercial legal systems can be built. The work involves 1) juridical ontology development, 2) metadata modeling of legislative documents, 3) publication of the content as linked data, and 4) evaluation of the system via application demonstrators.
The following metadata schema specifications have been published as part of the LDF.fi service:
Pilot datasets of statutes of Finnish legislation and court decisions are published in the LDF.fi service as Linked Data:
Semantic Finlex dataset page.
Examples in the dataset:
The data is also available as data dump files and can be queried from a SPARQL endpoint in the LDF.fi service.

Governments publish legislation and case law widely in print and on the Web. Such legal information is provided for human consumption, but the information is usually not available as data for algorithmic analysis and applications to use. However, this would be beneficial in many use cases, such as building more intelligent juridical online services and conducting research into legislation and legal practice. To address these needs, this Chapter presents Semantic Finlex, a national in-use data resource and service for publishing Finnish legislation and related case law as Linked Open Data for legal applications to use. The system transforms and interlinks on a regular basis data from the legacy legal database Finlex of the Ministry of Justice into Linked Open Data, based on the European standards ECLI and ELI. The published data is hosted on the 7-star Linked Data Finland service and SPARQL endpoint with a variety of related services available that ease data re-use. Rich Internet Applications using SPARQL for data access are presented as application demonstrators of the data service. In addition, this Chapter presents methods and tools under development to automatically annotate legal texts and to anonymize case law documents prior to their publication on the Web. Anonymization is necessary due to issues of data protection and privacy, and annotation is needed for semantic search and interlinking the documents. The automated approaches could significantly speed up the process and minimize costs of publishing legal documents as Linked Open Data.

Juridical information is important to organizations and individuals alike and is linked to from all walks of life. The Finnish government has published the Finlex Data Bank for searching and browsing legislation documents. However, the data there is not yet open, is based on a traditional XML schema, and does not conform to new semantic metadata standards. There are many difficulties in maintaining and using the site in, e.g., data harvesting, interoperability, querying, and linking that could be mitigated by the Semantic Web technologies. This paper presents an approach and a project—including first results—for publishing and using Finnish legislation as a 5-star Linked Open Data service.
