IntroductionIntroductionOnline communities of researchers

◦ Researchers working on common area, sharing

common interests

◦ Connected through blogs, social networks, etc

Information sharing needs of researchers

◦ Share information about publications

◦ Bookmark publications

◦ Comment on each others’ publications

◦ Bibliographic information should be structured

◦ Receive latest information from fellow researchers

◦ Flow of information among socially connected

researchers


IntroductionIntroductionNature of research communities

◦ Research communities are highly autonomous

◦ Different organizations, different systems

◦ Ad hoc and dynamic

◦ Researchers work on different topics at different times

Current bibliographic information systems

◦ Central bibliographic repositories (Citeseer, Google

scholar, DBLP, etc)

◦ Social collections (citeULike, BibSonomy, etc)

◦ Do not fully satisfy information sharing needs of research

communities

Problem StatementProblem StatementCurrent bibliographic information sharing

systems are centralized◦Central point of control

central point of failure◦One size does not fit all

dynamic and varied nature of research communities

Publishing systems and aggregation systems are isolated◦Effective information sharing needs both

Lack of proper flow on information in networked communities


Proposed SolutionsProposed SolutionsSocioBiblog Decentralized system

Publishing and Aggregation functionality in a single unit

Aggregation of information through Social Network links

Integration, filtering and mixing of information channels

Semantic BloggingSemantic BloggingBuilds upon traditional BloggingAdds semantic structure to blog itemsEnrich blog items with metadataCombines desirable features of Blogging

and the Semantic Web◦Blogging – easy personal publishing◦Semantic Web – standard structured

formats, interoperability

Semantic blogging can serve structured bibliographic information sharing between different systems


Adopted FormatsAdopted FormatsSWRC (Semantic Web for Research

Communities)◦ Ontology for modeling entities of research

communities (persons, organizations, publications, etc) and their relationships

◦ We use the Publication concept only

RSS (RDF Site Summary / Really Simple Syndication )◦ Format used to publish frequently updated

content such as blog entries and news◦ Allows compatible extensions


Adopted FormatsAdopted FormatsBuRST (Bibliography Management using RSS

Technology)◦ Lightweight specification for publishing

bibliographic information using RSS 1.0 and bibliography-related metadata standards

◦ Uses SWRC and FOAF

FOAF (Friend Of A Friend)◦ Popular metadata format for describing

people and relations between them

◦Web-based – centralized◦Standalone – cannot share information

online

Aggregate feeds on personal blogs◦Decentralized◦Personalized aggregation◦Sharing/redistribution of aggregated

contents

How to determine relevant sources?


Social Network based Social Network based AggregationAggregationResearchers are connected by social

network links (blogrolls, FOAF links) or co-authorship of publications

Closely related people have similar interests and are eager to share resources and communicate

Relevant resources may be aggregated from the social network neighborhood of a researcher◦friends and friends of friends

Facilitate flow of information in the social network



Social Network based Social Network based AggregationAggregation

Information Integration and Information Integration and MixingMixing

Information Source Integration◦ Aggregate information from multiple distributed

sources and integrate homogenously◦ Information Sources

Socially linked people

Bibliographic information sources

◦ Common semantic standards make integration possible

Metadata-based Filtering◦ Aggregated feeds may be filtered by metadata

elements◦ Semantic structure provides better fine grained control


Information Integration and Information Integration and MixingMixingMixing feeds

◦Customized information collection Can be used as new information source Can be mixed with other information

sources◦Integration, filtering and mixing can

form new powerful systems delivering useful streams of information

◦ Aggregate from friendship neighborhood up to two

levels deep

◦ Start from sources listed in Blogroll

◦ BuRST / RSS feed URLs can be retrieved from FOAF

profiles

FOAF crawler

◦ Gathers FOAF profiles in a database

◦ The crawled database can be searched for FOAF

links of authors


Aggregated search, filtering Aggregated search, filtering and mixingand mixingSearch and sort by SWRC fields –

ConclusionsConclusionsSocioBiblog - Semantic blogging platform for

decentralized sharing of bibliographic information

A single unit capable of both publishing and aggregating information

Act as an information broker to aggregate, filter and redistribute information

Flexible handling of information channels and emergence of useful customized information channels

Semantic Web offers the basis for structured information sharing and interoperability


Future WorkFuture WorkIncorporate domain ontology,

such as a topic hierarchyUse full features of the SWRC

ontologySemantic capabilities like

semantic search and navigationIndexing and ranked search

mechanismsSupport semantic blogging

clients like semiBlogUse wide variety of metadata


Thank you!Thank you!Questions / suggestions


BloggingBlogging Publicly accessible web-based publication of periodic

articles Usually in reverse chronological order Often serves as a personal journal

Easy publishing on the Web

Decentralized mechanism

Provides

◦ RSS feeds for aggregation

◦ Commenting mechanism

◦ Blogrolls

Foster communities


Semantic WebSemantic Web “The Semantic Web is an extension of the current web in

which information is given well-defined meaning, better

enabling computers and people to work in cooperation.”

The Semantic Web, Scientific American, May 2001,

Tim Berners-Lee, James Hendler and Ora Lassila

The Semantic Web is about two things

◦ Common formats for integration/combination of data

drawn from diverse sources

◦ Language for recording how the data relates to real world

objects
