Presentation Transcript

  1. Semantic Desktop • Getting semantics to help on the desktop may be THE challenge for Graphical User Interfaces in the next decade • Desktop semantics offer some general protection of privacy • Searching • Information Management • New ways to think about Personal Information Management • When we say “Desktop” do we mean “Personalization” or “Knowledge Management”?

  2. Personal Information Cloud • Vander Wal’s Model of Attraction • Your information has structure (and you understand it) • You are more involved with it in different contexts on different devices at different times • Re-using information (see contexts) is key • The current Web is (mostly) not like this • Stateless, memberships, non-open formats • You have to go to your information • Information should come to you, transparent of location • Re-use of information easier with structure & retrieval • Native understanding of user needs (it’s your information) • Metadata can be added explicitly or implicitly

  3. The Cloud that follows You • Information stays attracted to you • Sync, contextual portability are key • This key is enabled by semantics • Of the information • Of your situation

  4. Personal InfoCloud issues • Are we talking about Personalization? • TBL’s Semantic Web Agents? • Yahoo’s (Social Computing) 360? • How much control do you want to have? • Most people don’t even backup information or organize their bookmarks • The one time we organize our information? • For taxes. Do we need a Certified Public Information Cloudist? • What are the impacts for information system Designers? • User defined metadata & its (user contextual) appearance • Lightweight semantics universally accepted

  5. Semantic Desktop Outlook • Lots of people are working on it • RDF on the desktop • Ontology (matching or syncing) • Desktop agents • Web protocols work well on the desktop too • You already have a Web server installed on your computer, why not use it? • MIME types, open formats, DOM scripting, logic running on your own personal server • Do you have to be a system administrator (now)? • Does RSS go against this trend?

  6. Organic Semantic Desktop • Where will the SD come from? • Is it winner take all? • Who has the better pull? • Server = Google • Client = Microsoft (Apple) • Can it work like you do now? • What may need to be different? • Is different always better? • Semantic Desktops connected to the Web, build the Semantic Web one user at a time

  7. The usual (SD) suspects • Memex • HyperCard • Haystack • Protégé (expanded) • Outlook ? • Small pieces (address books, email clients, HTML documents) • Home Entertainment Media Hubs

  8. Semantic Desktop Building Blocks • Previously mentioned systems • Broadband, ubiquitous connectivity • Open source software • Web technology • Open document formats • New ways to store & organize information on the desktop • That might fight or confound current operating systems (file structures, app interop) • Drag & Drop vs. Search & Sort • What about Attraction & Agents? • Finding & Reminding • Ontologies & Taxonomies that are scaled down to desktop use & user mental models that change over time

  9. Building Blocks diagram

  10. Enabling Framework • Central RDF Repository • Central Search • Adapters (Sync, xfer, conversion) • Ontologies • Context Capture • Pluggable Architecture • How are these exemplified in SWT concepts we have discussed all semester?

  11. Wiring the Web • One view of using information if not semantically, at least more seamlessly • We have XML (RSS), Web Services, Mashups • A “mesh” can form by using simple scripting to wire components together • Can end-users build it? • What is the best metaphor to present it to users? • How can users move beyond the model of working with information of the server, by the server & for the server ? • Because I thought it was all about the users

  12. A Clipboard of the Web? • How can people move information around between uses; among different Web sites & services or even for contextual use on their own computers? • “Copy & Paste” needs a new metaphor then • Apple tried “Publish & Subscribe” • Isn’t subscribe what we say for (RSS) feeds now? • Live Clipboard • “ because we view “live” efforts as those providing users with seamless end-to-end scenarios that “just work” by weaving together the best of software and the best of services. “ Ozzie 2006 • What do you think? • Marketing spin? • A (desperate) attempt to keep you liking the desktop? • A bad metaphor and not very sophisticated interface model?

  13. Presentations • 10 minutes + questions • Any or all of the members may present • Demonstration of the project • Link to working demonstration that stays live for a week+ • Explanation of project ideas & technologies by using readings & discussions from class this semester • References, Bibliography of ideas & projects you were inspired or built upon
