Presentation at SemTech 2009

1. Making the Web Searchable Peter Mika Researcher, Data Architect Yahoo! Research

2. Yahoo! Research (research.yahoo.com)

7. Intro to the Semantic Web

15. URIs implicitly link data together (#joe, #name, “Joe A.”) (#joe, #email, mailto:joe@joe.com) (#mary, name, “Mary B.”) (#mary, gender, “female”) (#joe, #loves, #mary) Joe’s homepage A dating site Mary’s homepage (#name, #type, #Property) (#name, #domain, #Person) Schema doc Linked Data : Following links from one document to another allows to discover the entire graph (data and ontologies)

16. When put together, they form a single ‘global’ graph “ Joe A.” #joe #name “ joe@joe.com” #email #mary #loves “ Mary B.” “ female” #name #gender

17. The even larger picture: entire datasets connected

18. Publishing data on the Web

28. Metadata in HTML

32. SHOE system

33. SHOE Text-based query interface

34. SHOE Graphical Query Interface

39. Example: microformats <cite class=&quot; vcard &quot;> <a class=&quot; fn url &quot; rel=&quot;friend colleague met&quot; href=&quot;http://meyerweb.com/&quot;> Eric Meyer </a> </cite> wrote a post ( <cite> <a href=&quot;http://meyerweb.com/eric/thoughts/2005/12/16/tax-relief/&quot;> Tax Relief </a></cite> ) about an unintentionally humorous letter he received from the <span class=&quot; vcard &quot;> <a class=&quot; fn org url &quot; href=&quot;http://irs.gov/&quot;> Internal Revenue Service </a> </span>. <div class=&quot; vcard &quot;> <a class=&quot; email fn &quot; href=&quot;mailto:jfriday@host.com&quot;> Joe Friday </a> <div class=&quot; tel &quot;> +1-919-555-7878 </div> <div class=&quot; title &quot;> Area Administrator, Assistant </div> </div>

42. Microdata example <div item> <p>My name is <span itemprop=&quot; name &quot;> Neil </span>.</p> <p>My band is called <span itemprop=&quot; band &quot;> Four Parts Water </span>. I was born on <time itemprop=&quot; birthday &quot; datetime=&quot; 2009-05-10 &quot;>May 10th 2009</time>. <img itemprop=&quot; image &quot; src=” me.png &quot; alt=”me”> </p> </div

43. Slides courtesy of Mark Birbeck Introduction to RDFa

74. Semantic Web in Use

76. Example: ivan herman Related pages based on metadata Events from personal calendar, Conferences, and bio from LinkedIn Geolocation Rich abstract

77. Example: peter site:flickr.com Flickr users named “Peter” by geography

78. Example: san francisco conference Conferences in San Francisco by date

79. Example: greater st. peter Save to address book Call phone number (other actions)

83. Before After an open platform for using structured data to build more useful and relevant search results What is SearchMonkey?

84. image deep links name/value pairs or abstract Enhanced Result

85. YAHOO! CONFIDENTIAL | Infobar

86. SearchMonkey Acme.com’s database Index RDF/Microformat Markup site owners/publishers share structured data with Yahoo!. 1 consumers customize their search experience with Enhanced Results or Infobars 3 site owners & third-party developers build SearchMonkey apps. 2 DataRSS feed Web Services Page Extraction Acme.com’s Web Pages

87. Standard enhanced results Embed markup in your page, get an enhanced results without any programming

92. Developer tool: create custom presentations

110. Semantic Search and Navigation

114. Research on Semantic Search

117. Not just search…
