Slide 2

What is Semantic Web?

Slide 3

What is the Semantic Web? "An augmentation of the present Web in which data is given all around characterized importance, better empowering PCs and individuals to work in participation." Sir Tim Berners-Lee et al., Scientific American, 2001: tinyurl.com/i59p "… permitting the Web to achieve its maximum capacity… " with expansive outcomes "The up and coming era of the Web"

Slide 4

Semantic Web Tim Berners-Lee has a dream of a Semantic Web which has machine-justifiable semantics of data, and a huge number of little particular thinking administrations that offer help in mechanized errand accomplishment in light of the open data

Slide 5

The Semantic Web fundamentally "semantic" stands for "the significance of": The Beatles were a mainstream band from Liverpool; Lennon was an individual from the Beatles; "Hey Jude" was recorded by the Beatles The Semantic Web is a Web that can depict things in a way that PCs can prepare

Slide 6

Metadata and Semantics

Slide 7

Ontology The semantic Web is basically in view of ontologies are formal and consensual determinations of conceptualizations… giving a mutual and basic comprehension of an area that can be conveyed crosswise over individuals and application frameworks

Slide 8

An extremely straightforward Ontology Ontologies portray ideas and their Relations. claims Person Device is-a has Audio-Device VolumeControl

Slide 9

Semantic Web - Language tower Tim Berners-Lee Keynote Speech in 2005

Slide 10

What is Semantic Web for? Coordinating - attempting to take care of the issue of information and administration joining Searching - Providing better correspondence amongst human and PCs by calculator processable semantics to information.

Slide 11

Semantic Integration Top-Down approach: Building up various area ontologies for better information coordination and correspondence inside the space: PapiNet.org: Vocabulary for Paper Industry BPMI.org: Vocabulary for trading Business Process Models XML-HR: Vocabularies for (HR) DMTF: Distributed Management Task Force: Vocabularies for overseeing endeavors

WWW – Web 1.0

Slide 21

The ebb and flow (syntactic/basic) Web

Slide 22

Was the Web intended to be more?

Slide 23

How to understand Tim\'s vision Another possibility for "Counterfeit consciousness (AI)"? Information Representation (speaking to semantics) Logic Programming (thinking semantics) Decisions for: Background rationale for semantic web dialect (RDF, OWL) Description Logic DAPAR + EU = DAML+OIL (in 2001)

Slide 24

AI Influence Too much AI Ontologies are too overwhelming Too numerous maxims, confused standards, ideas and connections Things are excessively formal Too numerous formal rationale, rationale thinking, Knowledge base, master framework

Slide 25

Ontology or Oncology? Battle to shape a group EU financing – ontoweb extend ( http://cordis.europa.eu/ist/ka3/iaf/ventures/ontoweb.htm ) Lay the establishment for the introduction of the Semantic Web people group Now it is proceeded as KnowledgeWeb ( http://knowledgeweb.semanticweb.org/semanticportal/sewView/frames.html )

Slide 27

Semantic Web: Now

Slide 28

Social Web – Web 2.0 The term Web 2.0 was made well known by Tim O\'Reilly: http://www.oreillynet.com/bar/an/oreilly/tim/news/2005/09/30/what-is-web-20.html http://en.wikipedia.org/wiki/Web_2.0 "Web 2.0 … has … come to allude to what a few people depict as a moment period of design and application improvement for the World Wide Web." The Web where "normal" clients can meet, team up, and share utilizing social programming applications on the Web (labeled substance, social bookmarking, AJAX, and so forth.) Popular illustrations include: Bebo, del.icio.us, digg, Flickr, Google Maps, Skype, Technorati, orkut, 43 Things, Wikipedia…

Slide 29

Slide 31

When did Web 2.0 show up?

Slide 32

Features/standards of Web 2.0 http://www.oreillynet.com/bar/an/oreilly/tim/news/2005/09/30/what-is-web-20.html The Web as stage Harnessing aggregate knowledge Data is the following "Intel Inside" Rich client encounters

Slide 34

W3C SWEO Linking Open Data Project expects to Publish existing open permit datasets as connected information on the web Interlink things between various information sources Develop customers and applications that expend connected information from the web

Slide 35

Bubbles in May 2007 Over 500M RDF triples Around 120K RDF interfaces between information sources

Slide 36

Bubbles in April 2008 >2B RDF triples Around 3M RDF joins

Slide 37

Slide 39

What LOD can bring? It will lift current record web up to an information web LOD programs can give you a chance to explore between various information sources by taking after RDF joins. It can bore down to the lower granularity of the data permitting you for all the more fine pursuit on the web making the question-answer look on the Web conceivable lattice up various information through RDF joins Making the based on-top application simpler

Slide 47

The way to Web 3.0 (the Semantic Web) The Semantic Web exertion is fundamentally towards delivering measures and suggestions that will interlink information and applications The Web 2.0 is about giving client applications Not totally unrelated: http://www.oreillynet.com/xml/blog/2005/10/is_web_20_killing_the_semantic.html With a little exertion, many Web 2.0 applications can and do utilize Semantic Web innovations to incredible advantage

Slide 48

Document Web Glued by hyperlinks Data are HTML pages Query result is HTML pages, which can not be further prepared Data are quite recently interlinked, but rather not coordinated Data access through various APIs Data Web Glued by RDF joins Data are RDF triples Query result is RDF triples which can be effectively further handled (e.g., web administrations) Data are interlinked and coordinated, and connections are written Data access through a solitary and institutionalized get to system (possibly it will brought later on LOD API?) Document Web versus Information Web

Slide 49

Web 3.0 Social Web + Semantic Web  Next era Web Document Web  Data Web  Service Web

Slide 50

Will Google 2.0 be Semantic? Google could be superseded, says web innovator: TimesOnline: http://technology.timesonline.co.uk/tol/news/tech_and_web/article3532832.ece Google 2.0 grasps Semantic Web Government Computer News: http://www.gcn.com/on the web/vol1_no1/44290-1.html#
