A new release out of Freebase reports, “When we publicly launched Freebase back in 2007, we thought of it as a ‘Wikipedia for structured data.’ So it shouldn’t be surprising that we’ve been closely watching the Wikimedia Foundation‘s project Wikidata since it launched about two years ago. We believe strongly in a robust community-driven effort to collect and curate structured knowledge about the world, but we now think we can serve that goal best by supporting Wikidata — they’re growing fast, have an active community, and are better-suited to lead an open collaborative knowledge base. So we’ve decided to help transfer the data in Freebase to Wikidata, and in mid-2015 we’ll wind down the Freebase service as a standalone project. Freebase has also supported developer access to the data, so before we retire it, we’ll launch a new API for entity search powered by Google’s Knowledge Graph.” Read more

ElasticSearch 1.0 launches today, combining Elasticsearch realtime search and analytics, Logstash (which helps you take logs and other event data from your systems and store them in a central place), and Kibana (for graphing and analyzing logs) in an end-to-end stack designed to be a complete platform for data interaction. This first major update of the solution that delivers actionable insights in real-time from almost any type of structured and unstructured data source follows on the heels of the release of the commercial monitoring solution Elasticsearch Marvel, which gives users insight into the health of Elasticsearch clusters.
Organizations from Wikimedia to Netflix to Facebook today take advantage of Elasticsearch, which vp of engineering Kevin Kluge says is distinguished by its focus from its open-source start four years ago on realtime search in a distributed fashion. The native JSON and RESTful search tool “has intelligence where when it gets a new field that it hasn’t seen before, it discerns from the content of the field what type of data it is,” he explains. Users can optionally define schemas if they want, or be more freeform and very quickly add new styles of data and still profit from easier management and administration, he says.
Models also exist for using JSON-LD to represent RDF in a manner that can be indexed by Elasticsearch. The BBC World Service Archive prototype, in fact, uses an index based on ElasticSearch and constructed from the RDF data held in a central triple store to make sure its search engine and aggregation pages are quick enough.
Where in Paris might you find an exhibit featuring the artist Charles Le Brun?
If you didn’t know to check into the Musée du Louvre, Muséophile can help. Just plug in an artist or movement, and city, and see what comes to the fore. The service, still in beta, comes courtesy of Sémanticpédia, a platform for collaboration between France’s Ministry of Culture and Communication; INRIA, the country’s public institution of scientific and technological research; and Wikimedia France, whose aim is to perform research and development applied to corpus or collaborative cultural projects, using data extracted from Wikimedia projects.
Currently, data from French DBpedia is available for Sémanticpédia projects to leverage, and Muséophile is the first effort of the collaboration to do so. In fact, an overall effort by the government of France to boost the representation of French cultural resources on the web, which should aid in Muséophile’s continued development, is underway: Those within the Ministry of Culture and Communication with expertise in various content bases related to French culture are being charged to contribute their knowledge to the still youthful French DBpedia, which constitutes an extraction of structured information from the French Wikipedia. That will lead to a single reference system that they also can rely on to collaborate, and exchange and integrate data.
Richard Wallis is reporting from SemTechBiz in Berlin this week. He recently wrote, “One of the more eagerly awaited presentations at the Semantic Tech & Business Conference in Berlin today was a late addition to the program from Denny Vrandecic. With the prominence of Dbpedia in the Linked Open Data Cloud, anything new from Wikipedia with data in it was bound to attract attention, and we were not disappointed.” Read more
