RDF (Resource description framework) we can say that it is a metadata that is based on statement.

There are three concepts of RDF

Resource: Resource can be a thing that we are discussing and every resource on the internet have own url (Uniform resource locater)

Properties: Properties is the special kind of resource which describe the relation between resources

Statement: Statement represents the properties of resource.

RDF is a universal language that lets users describe resources using their own vocabularies

It does not make assumptions about any particular application domain, nor does it define the semantics of any domain

Before going toward the OWL (ONTOLOGY WEB LANGUAGE) we should know about the ontology

Ontology establishes the things that a system can talk and reason about. This means the vocabulary or just a collection of words and names

A key problem in achieving interoperability over the Web is recognizing when two pieces of data referring to the same thing, even though different terminologies are being used. OWL may be used to bridge this “terminology gap.”

Ontology includes four concepts that form the basis of an OWL document:

Class hierarchy: Defines class–subclass relationships

Synonym: Identifies equivalent classes and equivalent properties

Class association: Maps one or more classes to one or more classes,

Through the use of a property (i.e., domain/range)

Property metadata: Contains metadata for properties

Class definition: Specifies the composition of classes

Innovation comes from the professional life and with in professional it comes across on   specific field .I know many people will not satisfied with my definition  of innovation but let me explain .

When people doing start thinking about the problem which they are facing than might be some will go for research ,I must say  before before thinking on any thing  you should  go for research and collect the data and ideas .After collecting all stuff  you must come with some new ideas ,few years ago i was searching about the web ,efficient usage of web ,how to make web user friendly ,how ours search engine behave like human being and all such issues .Than i found a semantic web ,it still at beginning phase as my knowlege says ,No practical stuff was found but semantic web bring developers to new era of innovation  .

So back towards the  “Thinking “” point when you  start thinking about the problem than you get a pioneering  idea or some thing like this .

Than we have proposal and solution saga . Some times people gives idea from existing proposed solution and after studying those solution you may produce some  innovative ideas  that fulfill all requirements. Today many big companies learned from their past experience and research that all is the result of innovative ideas which helped them leading their businesses . i hope all of you  will agree with my point of view

So there is need to developed semantic agents using ontology and RDF schema and these agent work like an artificial agent, how these thing will solve ours problem, like in Pakistan it’s very difficult to get job after graduation on the contrast there is different companies in Pakistan who have vacant position in different category (java ,php ,QA ),

This is problem may solve using semantic in any job portal application ,I know there is different online application for job seeker and for companies but they don’t enough capable to overcomes this problem ,there is need of some semantic ,or we can say semantic agent who can resolve this problem ,we developed an application or we can say portfolio based on data mining and meta data in which job seeker just gives its information and interest ,and at the same time company gives its data along with available jobs ,than through semantic or we can say that semantic agent job seeker gets email only related to its interest like if he/she is searching for java based job in any company than they only receive java based job from different companies on the other end company can got email from people according to position vacant in company .

This my ideas to utilize ability of semantic web for overcomes our problem I need comments from

Every body to share their ideas about semantic web and its usage .

Some times i got an Exception just by roughly manual testing and some times unintentionally this make problems for developer ,i must say Tester should be think negative while doing testing this will help a lot for producing more bugs ,Most of the times Tester found UI bugs while testing on cross browser ,Mostly exeception found during the early stages of project ,

According to my Experience when u got a project for testing like for example user registrations Module first gives correct data and create an account ,than start testing on validation with different criteria .

if project has 4 module to test than at least gives 2 hours according to module to test on cross browser and test each and every that u think should be tested ,Try to find more bugs by doing full motivation towards the module .

At the end i must say manual testing is necessary for any application  to overcome the risk related to the application and provide a bug free application to client

The World Wide Web (WWW) has changed the way people communicate with each other, how information is disseminated and retrieved and how business is conducted. The term Semantic Web comprises techniques that promise to dramatically improve the current WWW and its use

Web intelligence is an issue of philosophy as much as application. It has been suggested that the next generation of Web architecture, the Semantic Web, creates an Artificial Intelligence (AI) application that will make Web content meaningful to computers, thereby unleashing a revolution of new abilities. More realistically, however, the Semantic Web may add semantics to the Web along with some limited AI capabilities to produce a more useful Web. Creating the Semantic Web with just the right balance between greater logic expressive power and achievable computer reasoning complexity is still being questioned and analyzed. An overly structured layering of many languages to deliver logic and machine processing would probably over-design the future Web architecture leading to a top-down command structure and weak adoption in the development community

. The introduction of Semantic Web concepts including XML and XML schemas, RDF and RDFS, OWL, Logic and Inference.

Searching the Web is an essential capability whether we are sitting at our desktop PC or wandering the corporate halls with our wireless PDA. As a result, the business of commercial search engines has become a vital and lucrative part of the Web. As search engines have become common place tools for virtually every user of the Web, companies, such as Google and Yahoo have become household names.

Last, but not the least, Jena is a Java API which can be used to create and manipulate RDF graphs. Jena has object classes to represent graphs, resources, properties and literals
