Shaping our futures: the Social Semantic Web

  1. 1. Digital Enterprise Research Institute Survival, Evolution or Extinction? Shaping Our Futures: the Social Semantic Web John Breslin © Copyright 2009 Digital Enterprise Research Institute. All rights reserved.
  2. 2. Social websites, semantics, and libraries Digital Enterprise Research Institute • A move from the Web to a “Social Web”: – Blogs, Wikipedia, Flickr, etc. – All powered by people and user-generated content – The blogosphere doubles in size every five months • [Digital] libraries need to participate in this ecosystem: – Contribute metadata to the ecosystem – Leverage the semantics being created by users 2
  3. 3. Explosion of social / collaborative websites Digital Enterprise Research Institute (disconnected)
  4. 4. From knowledge sharing to book recommendations Digital Enterprise Research Institute
  5. 5. Social websites and informal learning Digital Enterprise Research Institute • Estimates that 75-80% of learning is informal, and with 40-50% of employees accessing information and knowledge from the Social Web, it is potentially responsible for a large proportion of this informal learning (up to 30-40%): – “More than 40% of business users consume social networking applications like blogs, intranets and RSS feeds more than three times a week.” – “More than 30% of respondents read information in wikis, social networks, discussion boards and videoconferences / IMs more than three times a week.” – “More than 20% of respondents contribute to blogs, intranets, social networks, discussion boards, video conferencing and tagging more than three times a week.” •
  6. 6. Enabling users to easily data silos one with them Social websites are like bring data Allowing users to easily move from on these islands Need ways to connect users / their data to another Digital Enterprise Research Institute * Source: Pidgin Technologies,
  7. 7. What is the Semantic Web? Digital Enterprise Research Institute • Sir Tim Berners-Lee et al., Scientific American, 2001: – “An extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation.” • “Entrepreneurs see a Web guided by common sense”, John Markoff, New York Times, 2006: – “Referred to as Web 3.0, the effort is in its infancy, and the very idea has given rise to skeptics who have called it an unobtainable vision. But the underlying technologies are rapidly gaining adherents, at big companies like IBM and Google as well as small ones.” • Requires web pages to have metadata with underlying ontologies

  9. 9. Towards a Social Semantic Web Digital Enterprise Research Institute
  10. 10. Previously in digital content and digital libraries Digital Enterprise Research Institute • Digital libraries provide: – Databases and archiving (storage) – Digital bibliographic descriptions (metadata) – Full-text search (interface) • Advantages: – Content is accessible online – Federations of libraries, have to visit less places • Disadvantages: – Lonely users! – If we need to find the right keywords, there is no one to ask when we do not know them (e.g. “man without an ear” paintings) – Still many problems with connecting to other sources 10
  11. 11. Possibilities with today’s interlinked social media Digital Enterprise Research Institute • Towards social semantic information spaces: – Semantic descriptions (interconnected metadata) – Annotations provided by users (social metadata) – Collaborative search and browsing (interface) • Features associated with this: – Search and browsing based on semantics empowers users – Users contribute to the classification process – Users can understand community-driven annotations – Users enhance digital content using blogs, wikis on the side – Library can interact with other Internet services 11
  12. 12. JeromeDL, DERI’s social semantic digital library Digital Enterprise Research Institute • Integrated social networking with user profiling • Enhanced personalised search facility • Interconnects meaningful descriptions of resources with social media • Extensible access control based on social networks • Collaborative browsing and filtering • Dynamic collections • Integration with other Web 2.0 services • Open source!
  13. 13. Towards “Library 2.0” (3.0)? Digital Enterprise Research Institute • Users become active producers of the content and metadata JeromeDL can turn a single resource into a blog post: – Users can then annotate it – Users can also rank it – Metadata about user annotations is exported for other services • Community annotations for multimedia: – Region of interest (ROI) tagging in photos – Time-tagging of video streams (e.g. video lectures) • Other Web 2.0 services can easily hook up to the information and services provided by JeromeDL
  14. 14. Exposing semantics in library contents to search Digital Enterprise Research Institute • Yahoo! Search Monkey and Google Rich Snippets • Highlights the structured data embedded in web pages • Google developers have indicated that scholarly publications marked up with Rich Snippets will also be picked up and appropriately indexed by Google Scholar
