Inspired by the idea of Open Linked Data, the latest demo of the Gazettes’ faceted search released by the TSO Semantic Team fully exploits the Gazettes semantic data and uses semantic technology to answer very real business questions. The proof-of-concept integrates three data sources, published by different organisations and uses five star quality, uniformed format, Linked Data.
TSO has published the London Gazette notice metadata since October 2010. Hosted on TSO’s OpenUp® Platform, the Gazettes Resource Description Framework (RDF) repository provides access to over 120 thousand notices as Linked Data – translating into an impressive 10 million RDF triples, and this continues to grow every day.
The TSO team mashes up the Gazettes notice Linked Data together with Ordnance Survey (OS) geographical information and Companies House data. OS Linked Data such as UK administrative boundary and postcode data is stored in TSO’s OpenUp® Platform and the SPARQL endpoint is made available for public access. Companies House makes all UK company registrations available online via Linked Data Application Programming Interfaces (APIs).This joins the data mix and integrates with company profiles such as ‘nature of business’ to provide an impressive depth of information to trawl.
Powered by Apache Solr, the Gazette faceted search supports both full-text search of the notice content and real-time facet views to cover:
