JeromeDL Tutorial

Slide 1: Digital Enterprise Research Institute www.deri.ie JeromeDL the Semantic Digital Library Sharing and Interconnecting Knowledge Chapter  Copyright 2007 Digital Enterprise Research Institute. All rights reserved. www.deri.org

Slide 2: The World of Social Media Digital Enterprise Research Institute www.deri.ie 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 2

Slide 3: Motivation Digital Enterprise Research Institute www.deri.ie Corrib.DERI provides components for:   integration and search information from different sources  sharing and interconnecting knowledge among people 4 3

Slide 4: Yesterday’s world of digital content Digital Enterprise Research Institute www.deri.ie 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 4

Slide 5: Today of interconnected, social media Digital Enterprise Research Institute www.deri.ie 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 5

Slide 6: JeromeDL - Properties Digital Enterprise Research Institute www.deri.ie 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. 

Slide 9: Creating Semantics Digital Enterprise Research Institute www.deri.ie 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 9

Slide 10: Flexible access control Digital Enterprise Research Institute www.deri.ie 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 10

Slide 11: Search based on semantics Digital Enterprise Research Institute www.deri.ie 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 11

Slide 12: Search Beyond one JeromeDL Digital Enterprise Research Institute www.deri.ie 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 12

Slide 13: Browsing on semantics Digital Enterprise Research Institute www.deri.ie Dynamic collections  specified with triples filter or RDF query  easily extensible  demo TagsTreeMaps  filtering based on clustered tags  using treemaps to present the tag space  zoomable interface paradigm  demo 13

Slide 14: Browsing on semantics Digital Enterprise Research Institute www.deri.ie Exhibit (SIMILE, MIT)  powerful faceted filtering  rendering related dates on the timeline  rendering related places on the google maps  demo MultiBeeBrowse  collaborative browsing  allows to perform complex browsing operations  user can overview browsing context and look up  browsing history demo 14

Slide 15: Access to semantics Digital Enterprise Research Institute www.deri.ie 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  demo MarcOnt Mediation Services  15

Slide 17: Social Semantic Collaborative Filtering Digital Enterprise Research Institute www.deri.ie 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  demo on user/community profile (context) 16 17

Slide 18: Towards Library 2.0 Digital Enterprise Research Institute www.deri.ie 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  demo time-tagging of video streams  18

Slide 19: Beyond JeromeDL - connecting to Web 2.0 Digital Enterprise Research Institute www.deri.ie 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 19

Slide 20: Conclusions Digital Enterprise Research Institute www.deri.ie 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  20
