  4. 4. Page: 4 „We are drowning in information and starved for knowledge.“ Content is highly available through the Internet and the raising importance of cloud approaches Information are distributed over people and systems Data is available in various media and technical formats An efficient way for working with huge amounts of unstructured content.

  7. 7. Page: 7 Content Management Systems CMS are a single point of entry, providing consistency and the foundations for collaborative work with content CMS provide functionalities to handle large amounts of content:  Creation of new content  Editing of existing content  Organisation and management of content  Presentation of content Media-neutral data management (separation of layout and content) www.iks-project.eu Copyright IKS Consortium
  8. 8. Page: 8 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 www.iks-project.eu Copyright IKS Consortium

  12. 12. Page: 12 State of Play in Content Management Current solutions provide efficient ways to manage content Domain-specific requirements, like “multichannel content distribution” are addressed Content can be managed and presented in multi-media formats www.iks-project.eu Copyright IKS Consortium

  14. 14. Page: 14 Shortcomings of “traditional” CMS Contentis 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 www.iks-project.eu Copyright IKS Consortium
  15. 15. Page: 15 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 Content-and context-aware creation and presentation of content  Interaction with content on the users level of knowledge www.iks-project.eu Copyright IKS Consortium

  18. 18. Page: 18 The Semantic Web Thevision of the Semantic Web has been originally proposed by Tim Berners-Lee “TheSemantic 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 www.iks-project.eu Copyright IKS Consortium
  19. 19. Page: 19What are we talking about? Data Information ?Knowledge Wisdom www.iks-project.eu Copyright IKS Consortium
  20. 20. Page: 20 Data “Datais 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.” [Ackoff1989] Examples:  “John Smith” www.iks-project.eu Copyright IKS Consortium
  21. 21. Page: 21 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.” [Ackoff1989] Examples:  “John Smith is a name.” www.iks-project.eu Copyright IKS Consortium
  22. 22. Page: 22 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.” [Ackoff1989] Example:  “John Smith is a potential customer for your products.” www.iks-project.eu Copyright IKS Consortium
  23. 23. Page: 23 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.” [Ackoff1989] “Knowledge is knowing that Example: a tomato is a fruit; wisdom  „It would be right/wrong to sell the is knowing not to put it in a fruit salad.” product to John Smith.“ Brian ODriscoll www.iks-project.eu Copyright IKS Consortium
  24. 24. Page: 24 DIKW Hierarchy “Information is not knowledge, Knowledge is not wisdom, Wisdom is not truth, Truth is not beauty, Beauty is not love, Love is not music, and Music is the best.” Wisdom Frank Zappa, "Packard Goose" Knowledge Insight Meaning Information Data Context[Ackoff1989] www.iks-project.eu Copyright IKS Consortium
  25. 25. Page: 25 Lessons Learned Understand the need for an efficient content management solution What are the different „types“ of CMS and what do they provide? The shortcomings of existing content management solutions. Distinction among the terms in the DIKW pyramide (data, information, knowledge, wisdom) www.iks-project.eu Copyright IKS Consortium
