  • Schema 101Why Metadata Matters: From a Search Engine Perspective. By: Barbara Starr Twitter: @BarbaraStarr Email: bstarr@Ontologica.us
  • Meta Information ME• Pursued a doctorate in Artificial Intelligence from South My favorite author: Africa in the 80s. Isaac Asimov• Recruited to build intelligent/predictive trading systems on Wall Street• Migrated to government-based contracts, several of which turned into real world products like Favorite book: – SIRI (PAL from DARPA) – WATSON (Acquaint - IBM Watson Labs was a team I Robot member)• From the vantage of a semantic technologist, I keenly watched the evolution of the Semantic Web.• “Shocked into the real world” when working as a consultant @ Overstock• Today - Educator, Consultant, Developer. Favorite character: MULTIVAC By: Barbara Starr Twitter: @BarbaraStarr Email: bstarr@Ontologica.us Linkedin: http://www.linkedin.com/in/barbarastarr
  • Additional MetainformationFor the purpose of this talk: MY ROBOT or Artificially Intelligent Entity or Search Engine same-as
  • SEARCH ENGINE POINT OF VIEW How can I exploit metadata or “semantic search”?
  • SEARCH ENGINE POINT OF VIEW I can directly extract Searchmonkey 2008 information to enhance SERP displays tiles RICH SNIPPETS 2009
  • SEARCH ENGINE POINT OF VIEW I can search directly on consumed metadata!
  • SEARCH ENGINE POINT OF VIEW I can provide direct answers to queries by searching on consumed, verified and validated information
  • SEARCH ENGINE POINT OF VIEW I can even aggregate answers or deduce them (like a timeline of events)
  • SEARCH ENGINE POINT OF VIEW ? I can detect Penn Treebank tagset relevancy signals: i.e what content to show to what I can even use it in I can use it to audience conjunction with Assist in interpreting a machine learning user query techniques- to eg. Train other components
  • SEARCH ENGINE POINT OF VIEW Really interesting in terms of exposing long tail content too. It makes I meant the things findable for me beer brewer when pages are published in Arizona with structured markup!
  • SEARCH ENGINE POINT OF VIEW I could really use Multiple conflicting this stuff. And it vocabularies that I will is like the tower have to align internally of babel out and multiple syntax there! formats as well. ? Microdata Microformats RDFa Goodrelations for e-commerce I’m a Search Engine Robot Prior to Schema.org
  • SEARCH ENGINE POINT OF VIEW Time to get Serious!
  • What has been the history?RDFa exploded in 2012 – Source Peter Mika - Yahoo Another five-fold increase between October 2010 and January, 2012 Five-fold increase between March, 2009 and October, 2010 Percentage of URLs with embedded metadata in various formats
  • Current state of metadata on the Web• 31% of webpages, 5% of domains contain some metadata – Analysis of the Bing Crawl (US crawl, January, 2012) – RDFa is most common format• By URL: 25% RDFa, 7% microdata, 9% microformat• By eTLD (PLD): 4% RDFa, 0.3% microdata, 5.4% microformat – Adoption is stronger among large publishers• Especially for RDFa and microdata• See also – P. Mika, T. Potter. Metadata Statistics for a Large Web Corpus, LDOW 2012 – H.Mühleisen, C.Bizer.Web Data Commons - Extracting Structured Data from Two Large Web Corpora, LDOW 2012

  • Timeline of RDFa and Semantic Web AdoptionAs of Semtech 2011 Inevitable passage of Semantic Web adoption – culminating in schema.org
  • SEARCH ENGINE POINT OF VIEW A Search Engine alliance has the power to MANDATE Align and consume vocabulary and syntax! many vocabularies that may not be of interest to search engines? Rather mandate vocabulary And Syntax - microdata
  • Sample portion
  • SEARCH ENGINE POINT OF VIEW On the other hand – Not wise to ignore standards bodies like W3C No mandate on Syntax
  • SEARCH ENGINE POINT OF VIEW Did I tell you I don’t like spam?
  • SEARCH ENGINE POINT OF VIEW Ensure your data feeds match information with the structured markup or Make sure you are “metadata” on not cloaking by your web pages. feeding one set of information to me and another to human users!
  • SEARCH ENGINE POINT OF VIEW Serving RELEVANT ANSWERS are IMPERATIVE! & central to my very being! Your Logo
  • SEARCH ENGINE POINT OF VIEW ELSE I AM
  • SEARCH ENGINE POINT OF VIEW
  • SEARCH ENGINE POINT OF VIEW Adding context in search verticals really Google’s “SearchVerticals” helps me serve up relevant information Notice any correlations? (Seriously increases my I would advise you to! recall), as does geospatial information. Consumed information - Structured Data Dashboard
  • SEARCH ENGINE POINT OF VIEW “Amazing fact: same amount of computing to answer one Google Search query as all the computing done -- in flight and on the ground -- for the entire Apollo program! I also have a pretty good understanding of big data and web intelligence so I can leverage them! SIRI OH! and be sure to check out Moores law
  • SEARCH ENGINE POINT OF VIEW I can combine it with computer vision techniques. I can leverage metadata for better image search SIRI I can enhance user’s shopping experience.
  • SEARCH ENGINE POINT OF VIEW Symbolic reasoning vs stochastic reasoning (Latter is more like NLP or Know rather than page rank) Recognize? INTRODUCING THE KNOWLEDGE GRAPH
  • And if you thoughtSEARCH ENGINE POINT OF VIEW the knowledge graph was cool, Talk of increase in checkout the screen real estate knowledge and CTR?  carousel!
  • SEARCH ENGINE POINT OF VIEW Thank you for your time!  And just a bye-the-bye, this technology is still in it’s nascent stages. Can Resources to help you imagine what I will you! Make sure to be able to do soon? use them wisely! Barbara Starr Email: bstarr@ontologica.us Twitter: @BarbaraStarr
