The Web of Data is Gaining Mass (2011)

The Web of Linked Data is Gaining Mass
• 2013 stats: 2 289 public
datasets
− http://stats.lod2.eu/
• Growing exponentially
− see the dotted trend line
• Structured markup
− Schema.org; semantic SEO
• Enables better semantic
tagging!
− As there are more concepts and
richer descriptions to refer to

The FactForge Data
• DBpedia (the English version only): 496M statements
• Geonames: 150M statements
− SameAs links between DBpedia and Geonames: 471K statements
• NOW data – metadata about news: 128M statements
• Total size: 938М statements
− 656M explicit statements + 281M inferred statements
− RDFRank and geo-spatial indices enabled to allow for ranking and efficient geo-region constraints
• Available at http://ff-news.ontotext.com

News Metadata
• Metadata from Ontotext’s Dynamic Semantic Publishing platform
− Automatically generated as part of the NOW.ontotext.com semantic news showcase
• News corpus from Google since Feb 2015, about 10k news/month
• ~70 tags (annotations) per news article
• Tags link text mentions of concepts to the knowledge graph
− Technically these are URIs for entities (people, organizations, locations, etc.) and key phrases

Semantic Press-Clipping
• We can trace references to a specific company in the news
− This is pretty much standard, however we can deal with syntactic variations in the names, because state
of the art Named Entity Recognition technology is used
− What’s more important, we distinguish correctly in which mention “Paris” refers to which of the
following: Paris (the capital of France), Paris in Texas, Paris Hilton or to Paris (the Greek hero)
• We can trace and consolidate references to daughter companies
• We have comprehensive industry classification
− The one from DBPedia, but refined to accommodate identifier variations and specialization (e.g.
company classified as dbr:Bank will also be considered classified as dbr:FinancialServices)
