![]() ![]() An impressive demonstration of what can be done when you have structured data about ‘things’. Once identified they then display the structured data, screen right, to add value to the user experience by supplementing search results with facts. They are identifying concepts in search terms by matching them with their vast structured view of the world, populated from Freebase, search logs, and harvested structured data from crawled pages (much in form). Google Knowledge Graph is an impressive experiment on the Google search results page. As an added consequence of the decision to reference data sources, Wikidata should be able to reference sources not produced inside Wikipedia, library catalogues for instance. The data should be even more comprehensive and reliable as those URIs will reference the source data, not as it is today: a scrape and reformat of info-box mark-up. In a year or so’s time, when the URIs for this data start to be published, I predict that it will soon overtake Dbpedia’s place at the centre of the linked open data cloud. Avoiding concerns about suppressing diversity, the intention is to reference supplied facts not create a single truth. As images now are the info-boxes in all Wikipedia will be populated from Wikidata. ![]() Building on the successes of the Wikimedia Commons and Dbpedia, Wikidata will centralise the maintenance and publishing of facts from the many language versions of Wikipedia. Wikidata, launched at the sister Semantic Technology & Business conference in Berlin in February, confirming its goals to bring consistency and reusability to the masses of data in Wikipedia. A few things worth noting here include the acknowledgement of RDFa as equally, if not more, important as Microdata as a method of embedding structured data in web pages Microsoft using mark-up as a way to pass structured data between applications in Windows 8 GoodRelations, and rNews from the IPTC, are leading a growing number of extensions now in the pipeline to broaden the scope and depth of the ontology the introduction of External Enumerations to enable the referencing and inclusion of authoritative lists of things such as place names, currencies, and subjects in mark-up the proportion of crawled pages already containing mark-up has risen to 7-10% – that’s a heck of a lot of pages!. The session had the air of something that had been around for much more than the 12 months since its announcement. , as I posted on the day, was represented by a panel of interweb luminaries from the likes of the W3C, Google, Yahoo!, Microsoft, Yandex, New York Times, and Disney. Obviously, from the title of this post, it has something to do with, Wikidata, and the Google Knowledge Graph…. It has told me that things are a changing – I got that impression last year too, but more so this year. I am reflecting on what my week at the conference has told me. I am on the long flight back from the Semantic Tech & Business Conference in San Francisco to the good ol’ UK, to see how they got on with the Queen’s Diamond Jubilee festivities. I was toying with another title for this post – Yet Another Perfect Storm, but I think that particular metaphor (although appropriate here) has been somewhat over done.
