Your Digital Persona

• Digital trails/Digital traces/Digital Footprints
• Your identity online
• You need to control this, for people can assume information about you, you should be the authority on your own data
• This is what I call your lifelog, or your "Digital Persona"

Capturing your Digital Persona at Source : Lifelogging

• More and more transaction/social interactions are happening online
• This has been labelled 'The Disappearence of the Body'
• Our daily lives leave behind more evidence that we can collect and curate, and the indiscriminating collection of such evidence is what has been coined Lifelogging
• Lifelogging can either be :
  • Passive : storing by-productsof the life one would have lived anyways
  • Active : one surrounds oneself with sensors and information capture tools to create as rich a picture of one’s life as possible.

Passive Lifelogging

• 
• An example could be our very own Semantic Squirrels Group
• The identification of sources of “cheaply available” autobiographical information
• Surreptitious capture of autobiographical data
• Ethos: Storing information in its raw form, for future utility.
• Sources of information identified:
  • Calendar: iCal
  • Location information: GPS, Network Gazetteer
  • File System Information: PDFs, Documents
  • Web History information: Firefox
  • Email Information: Mbox
  • Media Playlist Information: Music
  • Contextual Info: Weather and News metadata

Lifelogging & Empowerment (1)

• Don't trust people to store your data on your behalf
• Capture your own context and your own content
• Store your own data, give yourself a WebID, and use that as the subject whenever you want to create data about yourself
• Garlik FOI request report
• Store your own data and use pushback technology like mhausenblas's RDF -> API RDF Pushback work
• Lifelogging: Privacy and Empowerment with Memories for Life
• Rutgers Uni., Hasan Elahi, who was arrested in 2002 on serious terrorism allegations despite being absolutely innocent of any criminal or terrorist activity, has taken to lifelogging and posting the information on the Web as a pre-emptive alibi, see: http://trackingtransience.net/
• JenniCam : A camera with a view the experiment was meant to enpower women ...

So how does Personal Information fit in with the Semantic Web

• Associative Querying
• My favourite TimBL picture :
• 

Ontomedia Ontology (1)

• http://purl.org/ontomedia/core/media
• Build an ontology for describing stories
• 

Sources of Information where people are leaving their digital trails' anyway...

• Mbox/Messaging
• Music
• WebBrowsing
• Geolocation (IP gazetteers e.g. skyhock)
• Social Network Info (FOAF - must most likely facebook, twitter, myspace, ...)
• Nepomuk SemanticDesktop in KDE 4.0 File Reading preferences
• Radio/BBC Programmes style data
• Blog Info

Augmenting context with external datasources

• Human memory, associative linking in memory
• Lateral thinking
• Context could include:
  • Weather Info
  • Day/Night Info
  • Indoor/Outdoors Info
  • News Info
  • Traffic Info/on one's route to work...

The FOAF Landscape as per Q1 2009

Future Direction

• Pudsey of a Friend (POAF)
• Full Text Search over FOAF files
• Grab all of it !
• Server to Server updates : P2P on the Web in an Open Manner :XMPP JQbus?
• OAuth which Interacts with 4store code to be released
• Release code snipbits for people to ping to the FOAF KB http://foaf.qdos.com/ping
• Release stats on connectivity and richness of FOAF data from different sites
• Find time and Write a paper :)
