Introduction<br />Web » a horde of valuable but unorganized and scattered documents<br />Web of document is not intelligible to machines but web of linked data is<br />Semantic Web » web of data<br />RDF graph » semantics underlying the document<br />bottleneck of emerging semantic web » conversion of html to RDF<br />

3.
Objective<br />Generate RDF from HTML document <br />Suggesting a framework titled ‘RDF by Structured Reference to Semantics’ or RS2 framework to do so<br />

4.
Overview: Web Versions<br />

5.
Why Semantic Web<br />QUERY:<br />Bangladeshi<br />player played in<br /> IPL<br />List of<br />

6.
Why Semantic Web<br />

7.
Semantic Web Stack<br />APPLICATION<br />QUERY<br />DATA<br />IN <br />ABSTRUCT FORMAT<br />MAP<br />DATA<br />IN <br />VARIOUS FORMAT<br />XML<br />URI<br />SYNTAX<br />

8.
Why RDF?<br /><ul><li>A simple RDF graph tells about who is the instance of which class.

9.
What is the relation between two instance.

10.
Ex:- Mashrafe play for Kolkata Knight rider. Mashrafe’s nationality is Bangladeshi.</li></ul>Player<br />Cricket Team<br />Country<br />Instance of<br />Instance of<br />Instance of<br />play for<br />nationality<br />Bangladesh<br />Mashrafe<br />Kolkata Nightrider<br />

11.
Architecture of RS2 framework<br />Extract plaintext<br />Parse Natural Language TEXT<br />plaintext<br />Parse tree<br />Yield SPO<br />Generate RDF<br />Lookup for Semantic equivalent<br />Subject<br />Predicate<br />Object<br />Semantic Web entities for SPO<br />

RS2 framework in action<br />RS2 <br />framework<br />lexicon<br />mapper<br />ontology<br />

13.
HTML to plaintext<br />Html tags don’t have sensible info<br />Strip them<br />Get the text that we actually read<br />

14.
Parse sentence<br />

15.
Yield Subject-Predicate-Object <br />

16.
Lookup semantic web entities<br />I think KKR and Kolkata Knight Raider are different<br />Same anomaly occurred for predicate and object<br />

17.
Lookup semantic web entities<br /><ul><li>Natural language subject, predicate and object is not recognizable by the machine.

18.
Convert it to a machine accessible way.</li></ul>KKRis located in Kolkata.<br />Kolkata Knight Rider is situated at west Bengal.<br />Natural Language<br />Subject<br />Predicate<br />Object<br />Kolkata Knight Rider location Kolkata.<br />RDF Triple<br />

19.
Generate RDF<br />

27.
Future Work and Benefits <br />An application/framework to enhance Web Ontology from knowledge conceived from html document<br />applications with Semantic Web features<br />Benefit:<br />Emergence of Semantic Web<br />Automatic conversion of piles of html into RDF graph<br />

28.
Conclusion<br />A framework and a prototype application to convert html document into RDF<br />Eliminate the bottleneck in the emergence of Semantic Web by RS2 <br />
