D7.3 Report: Curriculum and training material for university teaching
    • IKS in a Nutshell“Interactive Knowledge Stack” (IKS) is an integrating project targeting small to medium Con-tent Management Systems (CMS) providers in Europe providing technology platforms forcontent and knowledge management to thousands of end user organizations. Current CMStechnology platforms lack the capability for semantic web enabled, intelligent content, andtherefore lack the capacity for users to interact with the content at the user’s knowledge level.The objective of IKS therefore, is to bring semantic capabilities to current CMS frameworks.IKS puts forward the “Semantic CMS Technology Stack” which merges the advances in se-mantic web infrastructure and services with CMS industry needs of coherent architecturesthat fit into existing technology landscapes. IKS will provide the specifications and at leastone Open Source Reference Implementation of the full IKS Stack. To validate the IKS Stackprototype solutions for industrial use cases ranging from ambient intelligence infotainment,project management and controlling to an online holiday booking system will be developed.1 IntroductionThe main idea behind this deliverable is to aggregate the results that have been achieved inthe IKS project, resulting in a set of training material for university teaching. This training ma-terial consists of slide sets introducing and explaining relevant topics, demos showing con-crete application examples for the imparted contents and exercises that can be performed inorder to apply and deepen the gained knowledge. The objective of this teacher handbook isto provide an overview about the teaching material that has been created.In order to make the training material applicable in daily academic work in universities, thelectures are designed to be used in two different ways. The set of materials can be used as aconsistent, "out-of-the-box" curriculum as shown in the next section. For this purpose, thelectures can be used in the defined order.Since in some cases, only selected topics are relevant and should be used in an existingcourse, the material has a modular structure. Single lectures can be integrated in an existingcurriculum. In order to ease the integration previous knowledge and requirements are de-fined for each lecture.
    • 2 What is the Training Material about?The training material includes the main scientific finding of the IKS project described on anappropriate level of abstraction. In order to make these results usable in a course on univer-sity level, we also provide foundational lectures. These foundations are not an actual out-come of IKS but are required to make the more sophisticated content understandable tostudents. We identified four main topics that are relevant. These topics have been identifiedand refined as indicated in the mind map illustrated in Figure 1. Motivation Why do we need content Semantics management? What are „semantics“ and what is their role in computer science? Terminology Content andWhat are we talking about? Relevant terms and their Knowledge The Vision meanings.

How can interactive knowledge-supportedubiquitous IS be designed? Case Study on an intelligent bathroom. Figure 1:Mind map of relevant topics for training materialThe overall topic of the course is termed "Semantic Content Management Systems". The firstfoundational topic is Content and Knowledge Management in general. Hereby, the needfor CMS and KMS is motivated and relevant terms are introduced. The shortcomings of "tra-ditional" CMS are pointed out and discussed.The second foundational topic deals with the Semantic Web. Semantics are introduced as aconcept in computer science. Based on this, Tim Berners-Lees vision of "The SemanticWeb" is explained and the underlying technological foundations are introduced. As the archi-tectural backbone of the Semantic Web, the Semantic Web Layer Cake is introduced and therelevance of the different languages is discussed.
    • Applying these foundations, four levels of Semantic Content Management that are in thefocus of the IKS project are addressed. According to the four layers of the IKS Stack, we de-scribe the "Storing and Accessing of Semantic Data", i.e. the way meta data (knowledge) isstored and queried. Standards and techniques for the extraction of semantic data from con-tent (semantic lifting) are explicated and the design of complex knowledge domains and rea-soning about it is introduced. Finally, the presentation of knowledge to the user and a newway on interacting with content are described.Beside the specification of semantic content, an important focus of the IKS project is the in-vestigation of Methodologies for Developing Semantic CMS. A requirements elicitationprocess for semantic CMS is taught as well as a reference architecture that can be used tobuild a semantic CMS from scratch or to conceptually semantify a "traditional" CMS. The ac-tual extension of traditional CMS, e.g. by IKS services is also explained. Extending the usualunderstanding of CMS as software systems, we introduce a case study of an intelligent bath-room. Using this case study, a design methodology for knowledge-supported ubiquitous in-formation systems is presented.The curriculum is depicted in Figure 2.

    • 3 CurriculumIn order to make the training material usable as a “stand-alone” course, a curriculum is de-fined. In this curriculum, an order for the different lectures is set. Addressing the identifiedtopics illustrated above, the curriculum is structured as follows:Course Overview & Introduction introduces the presenter, provides organizational detailsand gives an overview about the course structure. The slides are very generic to be adapt-able to the actual course that is given. In order to introduce the main ideas of the project, aslideset about the IKS project is provided.Foundations aim for imparting the required foundations for the following lectures. The sec-tion introduces content management in general by motivating the need of CMS and gives anoverview about relevant terms in this domain. Identified shortcomings of "traditional" CMSare pointed out. The vision of the Semantic Web is introduced and the underlying technolo-gies are explained. Basic languages like RDF and OWL are introduced as a foundation forthe application of these technologies in the domain of semantic content management.Semantic Content Management presents different application areas for semantic technolo-gies in the field of content management. Starting with storing and accessing semantic data,approaches for semantic lifting and the ontology languages for the representation of knowl-edge are explained. Finally, semantic based interaction with content and the appropriatepresentation of content is addressed.Methodologies for Developing Semantic CMS gives an overview about challenges andbest practices for building semantic CMS from the software engineering perspective. This in-cludes the requirements engineering for semantic CMS, requirements for the architecture ofsuch systems and a systematic approach for semantifying a “traditional” CMS with semanticcapabilities is explained. A design methodology for ubiquitous information systems is intro-duced.The resulting lectures for the different topics are listed in the following.

    • 4 Training MaterialIn this section, an overview about the provided training material is given. The following tableshows all topics and the different types of training material that are available for this topic.Basically, four kinds of material have been created: SL Short lecture L Lecture E Exercise T TutorialIn order to ease the integration of lectures into existing courses, the required skill levels foreach lecture are stated. Since the training material (and the IKS project) addresses the per-spectives of two different research areas 1.) software engineering and 2.) experts in knowl-edge engineering focusing on IE/IR and semantic technologies. For this purpose, therequired skill level is refined to these two research fields. The levels of the required skills aremeasured by a simple metric: No previous knowledge required. Basic understanding about the important terms and their meaning is required. Advanced knowledge in the domain is re- quired. A detailed and deep knowledge about the concepts is required.
