Our lineage…

Memex (Vannevar Bush)
A memex is “a device in which an individual
stores all his books, records, and
communications.”
Augmenting Human Intellect
(Doug Engelbart)
“By „augmenting human intellect‟ we mean
increasing the capability of a man to approach a
complex problem situation, to gain
comprehension to suit his particular needs, and to
derive solutions to problems.”
WWW (Tim Berners-Lee)
“There was a second part of the dream […] we
could then use computers to help us analyse it,
make sense of what we re doing, where we
individually fit in, and how we can better work
together.”

A Network of Knowledge

 Interconnected
 Universal
 All encompassing

 Enable global and local
collaboration
 The right information for
the right people at the right
time

Our Hypothesis…

Collaborative access to networked knowledge assists
humans, organisations and systems with their individual
as well as collective problem solving, creating solutions
to problems that were previously thought insolvable, and
enabling innovation and increased productivity on
individual, organisational and global levels.

Inspired by Doug Engelbart’s original
1962 report of: AUGMENTING

From the Web to a “Social Web”

The New Yorker, 1993 The New Yorker, 2005

“On the Internet, nobody knows “I had my own blog for a while,
you’re a dog.” but I decided to go back to just
pointless, incessant barking.”

11

Features of Web 2.0 (O’Reilly)

1. The Web as platform
2. Harnessing collective intelligence
3. Data is the next “Intel Inside”
4. End of the software release cycle
5. Lightweight programming models
6. Software above the level of a single device
7. Rich user experiences
+ The long tail

12

Web 2.0 in simple terms

1. Users
2. Content
3. Tags
4. Comments
 Users post content
 Users share content
 Users annotate content with tags
 Users browse content via tags
 Users discuss content via comments
 Users connect via posted content
 Users connect directly to users

13

Serious Applications for Web 2.0

 Web 2.0 in researchenvironments
 UsingWikis for projectproposals
 Scientificblogging for communities (e.g. Nature network)

Enterprise 2.0

 Web 2.0 includes applications such as blogs, wikis, RSS
feeds and social networking, while Enterprise 2.0 is the
packaging of those technologies in both corporate IT
and workplace environments
 Corporate blogging
 Corporate wikis
 Social Networking inside organisations
 etc.

 “Enterprise 2.0 is the use of emergent social software
platforms within companies, or between companies
and their partners or customers”
 Harvard Business School‟s Professor Andrew McAfee

Enterprise 2.0 and the Web

 Many enterprises got an online presence on Web 2.0
services to reach their customers
 Twitter, Slideshare, Flickr, etc.

The SLATES acronym

 Andrew McAfee introduced the SLATES acronym to
identify the main features of Enterprise 2.0 systems
 Search
– Information must be easily accessible for knowledge workers
 Links
– Enable better browsing capabilities between content
 Authoring
– Easy interfaces to produce content, in a collaborative way
 Tagging
– User-generated classification, enables serendipity and knowledge
discovery
 Extension
– Recommendation of relevant content

Social aspects of Enterprise 2.0

 Enterprise 2.0 introduces new paradigms in
organisations with regards to knowledge sharing and
communication patterns
 The social aspect is as important than the technical
requirements
 Enterprise 2.0 is a philosophy
 Enterprise 2.0 success depends on a company‟s
background
 A study by AIIM showed that 41% of companies do not have a
clear understanding of what Enterprise 2.0 is while this
percentage goes down to 15% in KM-oriented companies.

Keys to Enterprise 2.0 adoption

 Combining top-down and bottom-up approach helps to
realize Enterprise 2.0
 Top-down: Hierarchy sets up new tools and requires various
services to use them
 Bottom-up: Users become evangelists and word-of-mouth
improves the number of new users
 “An adoption strategy for social software in enterprise”
– http://strange.corante.com/2006/03/05/an-adoption-strategy-for-
social-software-in-enterprise
 “MiddleSpace” by Ross Mayfield‟s (SocialText)
– http://many.corante.com/archives/2004/10/27/middlespace.php

Business metrics for Enterprise 2.0

 13% of the Fortune 500 companies have a public blog
maintained by their employees
 Forrester Research predicts a global market for
Enterprise 2.0 solutions of 4.6 billion dollars by 2013 and
according to Gartner , social computing platforms would
be adopted by companies in the next 10 years
 Lots of companies and products in this space:
 Awareness, Mentor Scout, Contact Networks, Microsoft
SharePoint, IBM Lotus Connections, SelectMinds,
introNetworks, Tacit, Illumio, Jive Software, Visible Path,
Leverage Software, Web Crossing, SocialText

introNetworks

21

Jive Software

22

Visible Path

 Visible Path powers “Hoover‟s Connect
 Lets users know how they're connected to companies and
people in the Hoover's database

23

Open-source applications

 Open-source Web 2.0 applications canbeefficientlyused
in organisations to build Enterprise 2.0 ecosystems
 Blogging: WordPress, b2evolution, etc.
 Wikis: MediaWiki, MoinMoin, etc.
 RSS readers and APIs MagpieRSS, etc.
 Integrated CMS: Drupal, etc.

Information fragmentation issues

 Heterogeneity of people, services, needs and practices
 Impliesthatvarious services and tools are deployed
 E.g. someuserswillprefer a wiki, another - a CMS, etc.
 By usingvarious services (blogs, wikis, etc.) information
about a particularobject (e.g. a project) isfragmented
over the company‟s network
 Getting a global pictureisdifficult
 Applications act as independent data silos, withdifferent
APIs, different data formats, etc.
 Data integrationcanbe a costlytask

Lack of machine-readable data

 Enterprise 2.0 enables and encourages people to
providevaluable content inside organisations
 Especiallywikis, collaborative and open knowledge bases
 Yet, information iscomplex to re-
use, generallylockedinside services and for human-
consumptiononly
 Lack of (common) meta-databetween applications
 Somequeriescannotbeansweredautomatically
 « List all US-basedcompaniesinvolved in sustainableenergies »
 « Whoisworking in company X for more than 6 years »

Tagging issues

 Taggingenablesuser-generated classification of content
withevolving and user-drivenvocabularies
 Avoid to learnpre-defined taxonomies or controlledvocabularies,
simpler for end-users
 Yet, itraisesvarious issues
 Tag ambiguity
– « apple »: fruit or computer brand ?
 Tag heterogeneity
– « Semtech », « semanticconference », « semtech09 »
 Lack of organisation
– No links between the tags « SPARQL » and « RDF »

Tagging issues –Use-case

 EDF R&D – http://retd.edf.fr
 > 3 years, 12257 tags, 21614 blog posts
 54.2% of tags used only one time, 75.77% uses <= 3 times
 Lots of valuable information lost in the long tail of tags
 Tagging and expertise gap
 194 items tagged with “TF” (= Thin Film)
– 1% of them tagged with “solar”
– < 0.5% of “solar” items tagged “TF”
 Both tags are weakly related from a co-occurrence point of view,
clustering cannot be efficiently used
 Valuable information gets lost !

The long tail of tags

Outline

 Overview of Enterprise 2.0
 Going further
 Use cases
 Conclusion

Enterprise 2.0: Semantics can help

 By using agreed-upon semantic formats to describe
people, teams, content objects and the connections
that bind them all together, Enterprise 2.0 applications
can interoperate by appealing to common semantics
 Developers are already using semantic technologies
to augment the ways in which they create, reuse, and
link profiles and content on social media sites (using
FOAF, XFN / hCard, SIOC, etc.)
 Hence, it can be applied to extend existing
architectures with simple and lightweight add-ons

Semantic Web in Enterprise

 Semantic Web technologies are already widely used in
organisations:
 Ontology-based information management
 Semantic middleware between databases
 Intelligent portals
 Etc.
 Semantic Web Education and Outreach (W3C)
 http://www.w3.org/2001/sw/sweo/public/UseCases/
 25 case-studies and 12 use-cases
 NASA, Eli Lilly, Oracle, Yahoo!, Sun microsystems, etc.

The (evolving) Semantic Web cake

 http://www.w3.org/2007/03/layerCake.png

Social Semantics ?

 The Semantic Web and the Social Web are not disjoint
 But can benefit of each other: Towards a Web of social and
interoperable data
 Semantics for the Social Web
 Using RDF(S)/OWL models to represent data from online
communities
 Social interactions for the Semantic Web
 Take advantage of social interactions to provide Semantic Web
data

Synergies for Social Semantics

“I think we could have Sir Tim Berners-Lee, podcast
both Semantic Web interview during ISWC 2005
technology supporting
online communities, but
at the same time also
online communities can
support Semantic
Webdata by being the
sources of people
voluntarily connecting
things together.” http://esw.w3.org/topic/IswcPodcast

Social Semantic Information Spaces

Semantic Enterprise 2.0 Architecture

 Lightweight add-ons to existing applications to provide
RDF data
 Exporters, wrappers, dedicated scripts …
 Takingintoaccount the social aspect (e.g. semanticwikis)
 Models to give meaning to this RDF data
 Domain ontologies, taxonomies, etc.
 Applications on the top of it
 Thanks to RDF(S)/OWL and SPARQL
 Most important, it does not require to rebuild IT
infrastructure but can be plugged on existing one !
 Inspired by Tim Berners-Lee RDF Bus

The RDF Bus approach

Example architecture

http://www.w3.org/2001/sw/sw
eo/public/UseCases/EDF/

Requirements

 How to produce RDF data
 Automatically and semi-automatically from existing applications
 How to find, re-use and define ontologies
 To model data contained in Enterprise 2.0 services
 How to build interfaces on the top of it
 Browsers, searchengines, mash-
upsthatprovideadvancedcapabilities

 We will now go in detail into these topics

Outline

 Solving Enterprise 2.0 issues with Semantics
 Going further
 Use cases
 Conclusion

Data models for Enterprise 2.0

 Twokinds of data models are required to
enableSemantic Enterprise 2.0
 Models for the structure of communities and their social
interactions
 FOAF – People, groups and enterprise social networks
 SIOC –Semantically-Interlinked Online Communities–
Interactions within the community
 Models of the content
 Domain-specific ontologies
 Taxonomies (SKOS)
 Reusingexisting public RDF data (Linking Open Data)

Ontology “Onion”

FOAF (Friend-of-a-Friend)

 FOAF is an ontology for describing people and the
relationships that exist between them
 Can be integrated with any other SW vocabularies
 Widely used on the Web:

 FOAF in Enterprise 2.0 settings
 Model individuals, teams, interests / skills, etc
 Allows one‟s identity to be modeled uniformly across various
applications
 Can be used for Expert finding

Distributedidentitywith FOAF

Social networking mining with FOAF

 Can use FOAF to describe social networks in your
enterprise in a machine-readable way
 Identify connections between people between various
applications and across departments

SIOC

 Semantically-Interlinked Online Communities
 http://sioc-project.org
 SIOC is an effort from DERI to discover how we can
create and establish ontologies on the Semantic Web
 Goal of the SIOC ontology is to address interoperability issues
on the (Social) Web, both at a Web scale and in organizations
 SIOC has been adopted in a framework of
50 applications or modules deployed
on over 400 sites
 As well as corporate use-cases, more later

Motivations for SIOC

 Disconnected social websites require semantics and
ontologies for interoperation:
 Lots of social data, inherent semantics (chicken and egg)
 Potential for high impact if widely adopted on the Web
 In parallel, lack of integration between social software
and other systems in enterprise intranets
 Information fragmentation issue, as previously detailed
 Enterprise 2.0 systems could be enhanced with semantics
 Need to understand how to socially create and establish
ontologies on the Web:
 Social engineering for ontologies, in contrast to authoritative
models
 Model, agree, deploy, get feedback, re-model, etc.

The steps involved

 Develop an ontology of terms for representing rich
information about user-created content
 Lightweight ontology, easily reusable
 Create a food chain for producing, collecting and
consuming SIOC data
 Open source applications to disseminate
 As well implementation via industry and research
projects utilizing SIOC
 An effort from both academics and industry
 A constant feedback process to ensure we follow the needs of
people using it

The SIOC ontology

 The main classes and properties are:

SIOC Specification:
http://rdfs.org/sioc/spec

The SIOC food chain

Adoption of SIOC

Using SIOC in Enterprise 2.0

 Using SIOC as an ontology to represent the activities of
Enterprise communities and their content
 Represent wikis, blogs, microblogging platform, etc. with common
semantics
 Enables interoperability between different service providers on
Enterprise 2.0 environments

 Helps to solve the information fragmentation issue
 As it eases the process of querying data from various sources
within the Enterprise
 Can be efficiently combined with other internal data (e.g.
taxonomies or knowledge bases to represent discussion topics)

Example of Enterprise 2.0 SIOC data

 John wrote meeting minutes on his team blog, powered by
Drupal:

:mypost rdf:type sioc:Post ;
dc:title “Meeting minutes” ;
sioc:has_creator :john ;
sioc:has_container :mydrupal .

:mydrupal rdf:type sioc:Forum .

57 of XYZ

Using the SIOC Types module

 For finer-grained content types, e.g. a wiki page:

:mypagerdf:typesioct:WikiPage;
dc:title “Understanding RDF” ;
sioc:has_creator :alex ;
sioc:has_container :mywiki.

:mywikirdf:typesioct:Wiki.

58 of XYZ

Combining with external ontologies

 To combine SIOC and other existing items, e.g. calendar
information:

:event rdf:type ical:VEVENT;
dc:title “Next meeting on friday” ;
sioc:has_creator :uldis;
sioc:has_container :mycal.

:mycal rdf:type sioct:EventCalendar .

FOAF + SIOC = user and services

61 of XYZ

FOAF + SIOC = Data Portability

Models to represent content

 A need for dedicatedmodels to represent content of blog
posts, wiki pages, etc.
 Taxonomies and controlledvocabularies
 Can beused to definesharetopicsacross applications
 SKOS – Simple Knowledge Organisation System
 http://www.w3.org/2004/02/skos/
 Specificdomain ontologies
 Check if existingmodelscan fit yourneeds
– Best practices documents, semanticsearchengines for ontologies
(e.g. Swoogle)
 Extend if needed, republish to get public feedback

Finding ontologies

 How to Publish Linked Data on the Web

Models for Semantic Tagging (1)

 Solving tagging issues thanks to semantics
 Common modeling between applications
 Linking to ontologies for further semantics
 The “Tag Ontology” by Newman from 2005
 tags:Tag rdfs:subClassOf skos:Concept
A “Tagging” class describes relationships between:
– A user
– An annotated resource
– Some tags

66

Models for Semantic Tagging (2)

 SCOT (Social Semantic Cloud of Tags):
 A model to describe tagclouds (tags and co-occurrence)
 Ability to move your own tagcloud from one service to another
 Share tagclouds between services, and between users
 “Tag portability”
 MOAT (Meaning of a Tag)
 A model to define “meanings” of tags using existing URIs
 e.g. SPARQL →http://dbpedia.org/resource/SPARQL
 Tagged content enters the “Linked Data” web
 Collaborative approach to share meanings in a community
– Servers can be installed in different departments / units

 Conclusion

Getting RDF data

 Data about the services, their structure and the people
 Can be completely automated thanks to RDF exporters for
FOAF and SIOC data
 Data about the content, i.e. knowledge contained in
wikis, blogs, etc.
 Generally requires end-user input
 Semantic Wikis
 NLP techniques can be considered

Generating SIOC data

 Exporters for major open-source applications
 Drupal, WordPress, phpBB, b2evolution
 To be included in Drupal7 core w/ RDFa !
 Exporters for semi-structured data
 IRC logs, .mbox files (SWAML project)
 APIs to create your own exporters
 Native applications exporting SIOC data
 E.g. SMOB: Distributed and open semantic microblogging
 http://smob.sioc-project.org

SIOC export APIs

 Benefits
 Hides the complexity from application developers
 Can be used by people who are not Semantic Web experts
 Automatically updated according to changes in the SIOC
ontology and best practices documents
 Existing SIOC APIs:
 Java
 Perl (new!)
 PHP (most used)
 RDFa on Rails
 See http://rdfs.org/sioc/applications/ (sec 2.1)

Overview of existing SIOC exporters

 There is a large amount of structured related
information contained within message boards, and this
can be leveraged in interesting ways by exposing the
semantic data for new applications
 Exporters have been developed for commercial
(vBulletin) and open-source (phpBB) message board
systems, bringing these islands together and allowing
conversations on topics that are taking place across
various sites in a company
 Based on the SIOC PHP API

vBulletin SIOC exporter

Issues withtraditionalwikis

 Structured access JohnGrisham
 Information reuse He is the author of PelicanBrief.
 Made for humans, He lives in Mississippi.
not machines He writes a book each year.
He is published by RandomHouse.

Structured access:
✗ Other books by JohnGrisham (navigation)
✗ All authors that live in Europe? (query)
Information reuse:
✗ The authors from RandomHouse (views)
✗ And what if I don't speak English? (translation)

Semanticwikis

 Capture or identify further information about the pages in
a formal language, so that machines can (at least
partially) process and reason on it
 Some systems focus on metadata about the content, some on
the social aspect, some on both
 A semantic wiki could be able to capture that an article about
SPARQL related to Semantic Web and present you with further
related information
 Various use-cases and prototypes
 Some are used for personal knowledge management, others
aimed at KM for communities
 http://www.semwiki.org/

Fromwikis to Semanticwikis

Structure and content

SemPerWiki

SemanticMediaWiki

 An extension of MediaWiki:
 Allows users to add structured data to the entries, turning it into a
semantic wiki
 Users can classify the “type” of links, e.g. making a relationship
such as “capital of” between Berlin and Germany explicit:
– ... [[capital of::Germany]] ... resulting in the semantic statement
"Berlin" "capital of" "Germany"
 On the page about Berlin, users can explicitly define its
population by writing:
– ... the population is [[population:=3,993,933]] ... resulting in the
semantic statement "Berlin" "has population" "3993933"
 Currently the most widely-deployed semantic wiki, Semantic
MediaWiki is also being used by various organisations, and is
being deployed as a service by Centiare and Wikia

Data integration and services

 Distributed querying
 Important to keep intact the decentralized architecture of the
ecosystem
 Still experimental, can be quite slow
 Central RDF storage
 Ensure better performances
 Using SPARQL to query data and to provide HTTP-based
interface on the top of the RDF store
– SPARQL is a W3C recommendations, current SPARQL WG
discusses evolution of the language
 Lots of solutions on the market
 OpenLink Virtuoso, Sesame, etc.

Data integration and services


 Facet can be a direct or
indirect property:
Direct
 The topic of the content item
 The creator of the item
 The date created

Indirect
 A geographic location of the
person who created it
 The gender of the person
 An interest shared by many

CWE Data Third-party
Application
SIOC Data

The CWE Interoperability Architecture provides a middleware that enables
multiple, independent CWE platforms and third-party applications to share
and correlate data, based on SIOC.


1. Concept Mapping: The first stage of translating proprietary CWE data into
SIOC RDF data involves mapping concepts that exist in a specific CWE
domain to concepts in the SIOC ontology.

2. SIOC Exporter: Based on the conceptual mappings, SIOC exporters translate
platform-specific data into SIOC RDF data.

3. Basic Collaborative Services (BCS): The BCS expose the content of a CWE
workspace as SIOC data to external systems. CWE items, such as documents
and folders, may be accessed, added, deleted, renamed, or replaced remotely

4. SIOC Importer/Viewer: Importing remote SIOC data into a CWE allows a user
to view data from a remote SIOC RDF source as if it was a local folder in the
CWE. The SIOC Importer/Viewer reverts the SIOC data into CWE platform-
specific data, based on the conceptual mappings.


 Workspace Synchronisation
 Sharing CWE files/folders between independent legacy CWE
platforms, e.g. BSCW, BC, SAP NetWeaver

 SIOC Xplore Widget
 Browsing across multiple, independent CWE platforms using a
single interface.
