Data Transformation, Interlinking and Enrichment
This task has two main goals. The ﬁrst goal is to adopt and deploy the LOD2 Stack to the datasets of Wolters Kluwer. These datasets cover all document types being normally used in legal publishing (laws and regulations, court decisions, legal commentary, handbooks and journals). The documents cover all main legal ﬁelds of law like labor law, criminal law, construction law, administration law, tax law, etc. The datasets also cover existing legal taxonomies and thesauri, covering each a speciﬁc ﬁeld of law, e.g. labor law, family law or social law. The overall amount of data (e.g. 600.000 court decisions) is large enough to make sure that the realistic operational tasks of a publisher can be executed with the data format and tools developed within the LOD2 project to support the respective use case. The datasets were analyzed according to various dimensions, e.g. actors, origin, geographical coverage, temporal coverage, type of data etc. relevant to the domain of legal information. Within the LOD2 project, all datasets were made available in formats adhering to open-standards, in particular RDF and Linked Data. Note that the datasets already existed in XML format at the start of the project and were transformed to RDF via XSLT script. The second goal is to automatically interlink and semantically enrich the Wolters Kluwer datasets. In order to achieve this, we leveraged the results from the LOD2 research work packages 3 and 4 (Chaps. 3 and 4) on the automated merging and linking of related concepts deﬁned according to different ontologies using proprietary and open tools. Data from external sources (German National Library, DBpedia, STW, TheSoz & EuroVoc) were used to enrich the Wolters Kluwer datasets to leverage their semantic connectivity and expressiveness beyond the state of the art. This effort resulted in operational improvements at Wolters Kluwer Germany (WKG) as well as added-value for WKG customers. WKG was expecting that high current internal (manual) efforts concerning taxonomy and thesaurus development and maintenance would partly be substituted by integrating external LOD sources. This held also true for speciﬁc metadata like geographical information, detailed information about organizations and typical legal content itself from public issuing bodies. The internal workﬂow at WKG would therefore be enhanced as automated alerting (e.g. push notiﬁcations, see Chap. 5) could be executed to inform internal editors of data changes based on the underlying interlinked data. This would be a major gain as this process is currently labor intensive as it requires editors to physically monitor changes to content.
