Web Content Management Systems (WCMS)
“A WCMS is a program that helps in maintaining, controlling, changing and reassembling the content on a web-page [...]. The user interacts with the system at the front through a normal web browser. From there he can edit, control parts of the layout and maintain and add to the web-pages without any programming or HTML skills.” - http://www.aiim.org/
WCMS are specific CMS, that focus on the management of digital data for web applications

Shortcomings of “traditional” CMS
Content is only “understandable” by users and not by machines Irrelevant search results Aggregation of relevant content needs to be done
manually
Inferring Knowledge from Content Dependencies, relations and inconsistencies among
content items need to be identified and defined manually

Requirements on CMS
Search Searching for keywords instead of formulating questions Manual identification and selection of relevant content Aggregation of content (possibly from different sources)
needs to be done by the user

The Semantic Web
The vision of the Semantic Web has been originally proposed by Tim Berners-Lee
“The Semantic Web is not a separate Web but an extension of the current one, in which information is given well-defined meaning, better enabling computers and people to work in cooperation.” [The Semantic Web, 2001]
Data can be processed manually by users and in an automated way

Data
“Data is defined as a symbol that represents a property of an object, an event or their environment. It is the product of observation but is of no use until its in a usable (that is, relevant) form. The difference between data an information is functional not structural.”
Examples: “John Smith”
Copyright IKS Consortium
18
www.iks-project.eu
Page:
Information
“Information is contained in descriptions, answers to questions that begin with such words as ‘who’, ‘what’, ‘when’ and ‘how many’. Information systems generate, store, retrieve and process data. Information is inferred from data.”
Examples: “John Smith is a name.”
Copyright IKS Consortium
19
www.iks-project.eu
Page:
Knowledge
“Knowledge is know-how, and is what makes possible the transformation of information into instruction. Knowledge can be obtained either by transmission from another who has it, by instruction, or by extracting it from experience.”
Example: “John Smith is a potential customer for your products.”

Wisdom
“Wisdom is the ability to increase effectiveness. Wisdom adds value, which requires the mental function that we call judgement. The ethical and aesthetic values that this implies are inherent to the actor and are unique and personal.”
Example: „It would be right/wrong to sell the
product to John Smith.“

“Knowledge is knowing that a tomato is a fruit; wisdom is knowing not to put it in a
fruit salad.”
