  • Impact of Open Data and Linked Open Data Venezuela Maria-Esther Vidal Universidad Simón Bolívar mvidal@ldc.usb.ve   h1p://www.ldc.usb.ve/~mvidal   Twi1er  @Maria11576561   Skype:  mevs2006   1  
  • Lights  around  the  London's  2012  Olympic  stadium  describe  Sir  Tim  Berners-­‐Lee's  invenKon,  the     World  Wide  Web.  The  Open  Data  InsKtute,  which  he  co-­‐founded,  declares  a  mandate  of    'Knowledge  for  Everyone'.  
  • “The  ODI  announced  new  13  nodes:   US,  Canada,  France,  Dubai,  Italy,   Russia,  Sweden  and  ArgenKna.”   Oct  29    2103   Sir  Tim  Berners-­‐Lee  (right)  and  Sir  Nigel  Shadbolt  (leT)  
  • Agenda Ø Open Data Ø Linked Open Data ü Linked Open Data in Journalism Ø Linked Open Data Applications ü Linked Open Data at USB Ø Conclusions and Future Directions
  • OPEN  DATA  
  • Open Data Definition http://opendefinition.org/: “A piece of data or content is open if anyone is free to use, reuse, and redistribute it — subject only, at most, to the requirement to attribute and/or share-alike.” Open_Data_stickers.jpg 1,024×768 pixels 7/1/13 9:33 PM Availability and access Reuse and Distribution Universal Participation 6  
  • Open Data  Availability and Access: Data should be available as a whole, preferably downloading via the Internet. Data should be available in a convenient format. Should be free or at most at a reproduction cost. 7  
  • Open Data   Reuse and Distribution: Data should be offered in a way that it can be reused, distributed and be interrelated with other datasets. 8  
  • Open Data   Universal Participation: Any person should be able to use, reuse and distribute. NO discrimination: Commercial vs. NOT commercial Educational vs. NOT educational Profit vs. No Profit 9  
  • Type of Open Data
  • Why Open Data? Interoperability   Transparency   11  
  • Why Open Data? Avoid  CorrupKon   Wealth   Only  in  Europe  over  140  billion  of  euros  per  year   h1p://www.economist.com/news/business/21578084-­‐making-­‐official-­‐data-­‐publi could-­‐spur-­‐lots-­‐innovaKon-­‐new-­‐goldmine   12  
  • Why Open Data? Research  and  Development   Quality  of  Life   13  
  • Why Open Data? Improve  Public  AdministraKon   Data  Quality   14  
  • Why Open Data? Citizens can express themselves and unite so that their voices can be heard. 15   h1p://www.ted.com/talks/sanjay_pradhan_how_open_data_is_changing_internaKonal_aid.html  
  • Open   Licenses   Open  Data   Open   ParKcipaKon   Open  Source   Open   Standards  
  • What is and what is not Open Data Open  Data.   “A piece of content or data is open if you are free to use, reuse, and redistribute it — subject only, at most, to the requirement to attribute and share-alike.” Difference between open data and data that is publicly available lies in the use of formats that may be read, used and redistributed by any citizen. Examples of public data that is not open data: data in spreadsheets, pdf, etc. Usually open data are csv. h1p://opensource.com/government/10/12/what-­‐“open-­‐data”-­‐means-­‐–-­‐and-­‐what-­‐it-­‐doesn’t  
  • Opening Up Data Rules Ø  Keep it simple Ø  Engage early and engage often Ø  Address common fears and misunderstandings Four Steps Ø  Choose your Dataset(s) Ø  Apply an Open License Ø  Make the data available Ø  Make it discoverable
  • Open Data Conditions Data Providers Requirements Distributing Open Data Ø  Attribution: data providers may require to receive credit. Ø  Integrity: data providers may require that users indicate if data change. Ø  Share-alike: data providers may impose that any dataset created using their data are also open. Ø  Data is machine-readable Ø  Data is available in bulk more than using an API. h1p://opendatahandbook.org/en/

  • Local  Governments  must  use   Open  Data  to  stay  connected   with  the  ciKzens!  
  • MoKvaKon  SemanKc  Web  EvoluKon   The Linked Open Data cloud, using the Web to connect related data that was not previously linked! Published Data are enhanced with semantics! Standards to annotate and describe data: XML, RDF, RDFS, OWL. Standards to query data: SPARQL. Ontologies representing almost any domain. Hyperlink-based systems. Protocols: http, uri, html Documents and data were published Arpanet: four servers connected Files were transferred Tools: ftp, telnet, e-mail 80’s IRMLs  2010-­‐ESWC  2010   90’s 00’s Now
  • The Linked Open Data Cloud • Explosion in the number of:     – Linking Open Data resources and databases – Different quality parameters. Molecular databases 1170, 95 more – Controlledthan 2008 and 110 more than the year before ! vocabularies: – MeSH, GO, PO… tools published Services and – Highly interconnected by these databases follow a similar progression! data sources: In October 2007, Cloud of Linked Data Different Sizes datasets consisted of over two billion RDF triples, Many links which were interlinked by over two million RDF links. • Different in- and outBy May 2009 this had grown to 4.2 billion RDF triples, degrees, etc interlinked by around 142 billions RDF links! Today • Biological Web: large the Linked Open Data cloud has at least 295 datasets, datasets of linking data. 31,634,213,770  triples, and 503,998,829  links. • Genes, Diseases, Clinical Drugs, Proteins, and so on.

  • LINKED  DATA  IN  JOURNALISM  
  • Open Data in Journalism   Ø It may be trendy but not new. Ø Open Data implies Open Data Journalism. Ø Data is not necessarily curated. Ø Bigger Datasets and Small Things. Ø Data Journalism is 80% perspiration, 10% great ideas, 10% output. Ø Long and short-form. Ø Anyone can do it. Ø Visualization is important. Ø Data publishers do not have to be programmers. Ø It is all about stories. h1p://www.theguardian.com/news/datablog/2011/jul/28/data-­‐journalism

  • More   Ontologies  to   represent   Meta-­‐Data  
  • VISUALIZING  LINKED  OPEN  DATA  
  • Challenges  for                                                                    Linked  Data   Visualization   •  Enabling  user  interacKon   –  Users  must  be  able  to  navigate  through  the  data  by  exploiKng  the   connecKons  between  Linked  Data  resources   –  The  user  might  edit  the  underlying  data  to  enrich  it  by:     •  CreaKng  addiKonal  metadata   •  HighlighKng  or  correcKng  errors   •  ValidaKng  data   •  SupporKng  data  reusability   –  The  output  (the  plo1ed  data  or  the  visualizaKon  itself)  might  be   encoded  using  standard  ontologies  and  vocabularies       •  Scalability   –  Linked  Data  visualizaKon  techniques  should  support  the  display  of   large  amount  of  data  in  an  efficient  way   EUCLID  –  InteracKon  with  Linked  Data   74  
  • Challenges  for                                                                    Linked  Open   Data  Visualization   •  ExtracKng  data  from  different  repositories   –  A  Linked  Data  set  might  be  parKKoned  into  several  repositories     –  The  region  of  interest  (ROI)  might  include  data  from  different  data   sets,  requiring  the  access  to  distributed  repositories   •  Handling  heterogeneous  data   –  The  same  data  (concepts)  might  be  modeled  differently,  for  example,   using  different  vocabularies   –  Certain  values  might  have  different  formats,  for  example,  dates   represented  as  DD-­‐MM-­‐YYYY,  MM-­‐DD-­‐YYYY  or  just  YYYY   •  Dealing  with  missing  values   –  Due  to  the  semi-­‐structuredness  of  Linked  Data,  some  instances  might   have  missing  values  for  certain  properKes   EUCLID  –  InteracKon  with  Linked  Data   75
