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

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

Corrib.DERI provides components for:

integration and search information from different sources

sharing and interconnecting knowledge among people

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

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

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

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

Metadata and Services in JeromeDL 9 Digital Enterprise Research Institute www.deri.ie

Semantic Metadata and Services 10 Digital Enterprise Research Institute www.deri.ie

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

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

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

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

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

Natural language templates

easily internationalized

Semantic Query Expansion (beta)

refines query based on current context

extensible context definition: user profile, history of queries, current query, etc.

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

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

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 )

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

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

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

Other Web 2.0 services can easily hook up to information and services provided by JeromeDL

Example - notitio.us

contains components familiar from JeromeDL

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
