Supporting such processes at their levels requires modeling and enacting several different forms of knowledge. In general, more explicitly represented knowledge allows better support. But different forms of knowledge need different intuitive and adequate representations and inferences. There are several methods to formally represent knowledge. Graphical models can be an intuitive means to add knowledge to knowledge-based systems. Instead of manually creating knowledge bases, knowledge can also be learned from data. We distinguish between symbolic learning (learning decision trees and case-based reasoning) and sub-symbolic learning (neural networks) After completion of this module, the participants will be able to assess which kind of knowledge representation and reasoning is adequate and are able to develop appropriate knowledge-based systems. They can value the advantages of knowledge-based systems with respect to their costs and apply several methods to create knowledge bases. </WRAP> ---- ===== Course Contents ===== <WRAP round 95% center box> * Introduction: Knowledge in processes * Decision Tables * Rules * Textual represented rule (i.e. Horn clauses) * Forward and backward chaining * Data-driven and Goal-oriented * Negation-as-failure * Fuzzy Logic * Knowledge Graphs * RDFS * Ontology Engineering * Graphical Models * Modelling and Meta-modeling * Ontology-based meta-modeling </WRAP> ---- ===== Study material ===== <WRAP box round center 95%> **Course Material** * Organisation * Slides: {{ :didattica:ay2324:kebi:ke-0-organization.pdf |About Lecture and Lecturers}} * Project work: *Project description: {{ :didattica:ay2324:kebi:project_personalized_menu_v1.pdf |Project description}} *Guide on how to install AOAME locally for Task 2: [[https://github.com/BPaaSModelling/AOAME]] * Lecture "Introduction" * Slides: {{ :didattica:ay2324:kebi:ke-1-introduction.pdf |Introduction}} * {{ :didattica:ay2324:kebi:davenport_2010_process_management_for_knowledge_work.pdf |Davenport, T.
