Limitations of Current Knowledge Management Technologies

Searching informationKeyword-based search engines

Extracting informationhuman involvement necessary for browsing, retrieving, interpreting, combining

Maintaining informationinconsistencies in terminology, outdated information.

Viewing information

Impossible to define views on Web knowledge


15/21

Semantic Web Open Standards

RDFStore data as triplesTriples the subject,the predicate, the object.

OWLDefine systems of concepts called ontologies

Sparql Query data in RDF

SWRL Define rules

GRDDL Transform data to RDF

Ontologies are like electronic dictionary that allows the

software to understand the meaning of the words

To develop a system where the answers can be

calculated using the data and ontologies to give a reply

automatically

The Semantic Web refers to a technology thatdescribes things in a way that computers

applications can understand it. It does not meanthe links between the web pages. This is about

machines talking to other machines.


19/21

1. Web Ontology Language (OWL): is used by applications thatprocess the content of information.

2. Resource Description Framework (RDF): This refers to alanguage for describing information and resources on the web.The Semantic Web uses this language to define web resources.

3. RDF Schema: It does not provide a vocabulary of application andproperties. Instead, it gives the facilities required to describe suchclasses and properties, and to indicate which classes and

properties are expected to be used together.

Elements of Semantic Web


20/21

This technology has the ability to describe what each

piece of information stands for, tag content on the Weband provide semantic meaning to the content item.

It makes the search engines more effective andefficient than they are currently, and users can find

the exact information they want.http://4.bp.blogspot.com/_aadpxuCT7nQ/SydULsHYzcI/AAAAAAAAAPI/nlaLZftqp-c/s400/Custom+Web+Solutions.jpg
