Real-time #SemanticWeb in <= 140 chars




     Linked Data on the Web (LDOW2010)
                April 27th, 2010
Structured data from microblogs

        •   Semantic Web

            •   typically published in large chunks

            •   relatively static



        •   microblogs

            •   published in tiny chunks

            •   600+ per second

            •   is any of this data useful?

            •   what can we capture?

                       2
Data about people

•
                                           Zhenning Shangguan
    users and accounts

•   use FOAF and SIOC

•   e.g. SemanticTweet (Flinter)



                                    3
Data about tweets

                           sioct:MicroblogPost
                   "At #ldow2010 (part of #www2010) ..."


                      sioc:has_creator

                                     sioc:has_container

                sioc:UserAccount
                     @joshsh
                                             sioct:Microblog
                                          @joshsh's Twitter timeline



•   blogs and posts

•   use SIOC and SIOC Types

•   e.g. SMOB (Passant et al.)


                                     4
What about data in a tweet?

                       sioct:MicroblogPost
               "At #ldow2010 (part of #www2010) ..."



                    sioc:embeds_knowledge




               #ldow2010 pmlr:partOf #www2010




•   nanotations: structured information in microblog
    posts




                                 5
TwitLogic


•   capture microblog data...

    •   ...including nanotations

•   translate it into RDF

•   produce an RDF stream

    •   ... and expose it as Linked Data

•   search and query in real time




          6
TwitLogic architecture




           7
For example...

  #sioclog (see http://bit.ly/2uAWo2) makes
          Linked Data from IRC logs.



 Who would have guessed such a funny movie as
#ZombieLand (3/4) could be made around zombies?



#websci2010 (= #websci10) is all atwitter with
  presentations containing the word "tweet".
