JeromeDL is a social semantic digital library that allows users to: 1) Contribute metadata and annotations that are interconnected within the library and on the semantic web. 2) Perform personalized, collaborative search and browsing based on semantics. 3) Access and share knowledge through integrated social networking features and extensible access controls.

- 2. The World of Social Media the Web is an ecosystem of social media Flickr, blogs, wikipedia, etc. blogosphere doubles every 6 months Digital libraries need to participate in this ecosystem contribute metadata to the ecosystem leverage on the semantics 3 Digital Enterprise Research Institute www.deri.ie
- 3. Motivation Corrib.DERI provides components for: integration and search information from different sources sharing and interconnecting knowledge among people 4 Digital Enterprise Research Institute www.deri.ie
- 4. Yesterday’s world of digital content Digital library Database and archive (storage) Digital bibliographic descriptions (metadata) Full-text search (interface) Pros: Content accessible online Federations of libraries – visit less places Cons: Lonely user No one to talk to, we need to find the right keywords, what if we do not know them (“man without an ear” paintings example) Still many problems with interconnecting other sources, incl. libraries 6 Digital Enterprise Research Institute www.deri.ie
- 5. Today of interconnected, social media Social Semantic Information Spaces Semantic description (interconnected metadata) Annotations provided by users (social metadata) Collaborative search and browsing (interface) Features 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 7 Digital Enterprise Research Institute www.deri.ie
- 6. JeromeDL - Properties JeromeDL is the social semantic digital library that provides Integrated social networking with user profiling. Enhanced personalized search facility. Interconnects meaningful description of resources with social media. Extensible access control based on social networks. Collaborative browsing and filtering. Dynamic collections. Integration with Web 2.0 services. Digital Enterprise Research Institute www.deri.ie

- 8. Semantic Metadata and Services 10 Digital Enterprise Research Institute www.deri.ie
- 9. Creating Semantics Each resource is described with: structure annotations - chapters, media parts, attachments basic bibliographic annotations knowledge organization systems - keywords, categories other semantic annotations social annotations (soft semantics) Resource can be annotated with hard semantics during the uploading process demo Digital Enterprise Research Institute www.deri.ie
- 10. Flexible access control Identity management based on social networks support for social networking metadata standard (FOAF) users and authors are part of a community Access control module apply access control licenses to resources and services defines atomic protections based on IP or position in the social network is easily extensible demo Digital Enterprise Research Institute www.deri.ie
- 11. Search based on semantics Natural language templates allows to perform complex queries using natural language can be created and modified based on the needs of users easily internationalized Semantic Query Expansion (beta) refines query based on current context extensible context definition: user profile, history of queries, current query, etc. demo Digital Enterprise Research Institute www.deri.ie
- 12. Search Beyond one JeromeDL Distributed search Extensible Library Protocol based on HyperCuP P2P infrastructure Federated Search Hierarchical order of JeromeDL instances Exposing resources bottom-up OAI-PMH (alpha) Harvesting other libraries Exposing resources to other libraries demo Digital Enterprise Research Institute www.deri.ie
- 13. Browsing on semantics Dynamic collections specified with triples filter or RDF query easily extensible TagsTreeMaps filtering based on clustered tags using treemaps to present the tag space zoomable interface paradigm demo demo Digital Enterprise Research Institute www.deri.ie
- 14. Browsing on semantics Exhibit (SIMILE, MIT) powerful faceted filtering rendering related dates on the timeline rendering related places on the google maps MultiBeeBrowse collaborative browsing allows to perform complex browsing operations user can overview browsing context and look up browsing history demo demo Digital Enterprise Research Institute www.deri.ie
- 15. Access to semantics Exposing underlying semantics rendering RDF in various flavors exposing semantics in JSON and SIOC syndication feeds (RSS) Querying semantic database RDF query endpoint OAI-PMH (beta) Delivering metadata to other services MarcOnt Mediation Services demo Digital Enterprise Research Institute www.deri.ie
- 16. Semantic Metadata and Services 15 Digital Enterprise Research Institute www.deri.ie
- 17. Social Semantic Collaborative Filtering Why? The bottom-line of acquiring knowledge: informal communication (“word of mouth”) How? Everyone classifies (filters) the information in bookmark folders ( user-oriented taxonomy ) Peers share (collaborate over) the information ( community-driven taxonomy ) Result? Knowledge “flows“ from the expert through the social network to the user System amass a lot of information on user/community profile ( context ) 16 demo Digital Enterprise Research Institute www.deri.ie
- 18. Towards Library 2.0 Users become active producers of the content and metadata JeromeDL turns a single resources into a blog post: users can annotate it users can rank it metadata about user annotations is exported in SIOC Community annotations for multimedia (alpha): region of interest (ROI) tagging in photos time-tagging of video streams demo Digital Enterprise Research Institute www.deri.ie
- 19. Beyond JeromeDL - connecting to Web 2.0 Other Web 2.0 services can easily hook up to information and services provided by JeromeDL Example - notitio.us aggregates semantics from different sources, including JeromeDL involves users in providing more annotations exposes content to other services, such as Learning Management Systems contains components familiar from JeromeDL demo Digital Enterprise Research Institute www.deri.ie
- 20. Conclusions JeromeDL delivers a set of components that enables semantic web technology It enhances users experience through the social interactions It uses semantics existing on the web It delivers semantics for other services Digital Enterprise Research Institute www.deri.ie
