The following tutorials were accepted after our Call for Tutorials:

• Modeling Decision Support for Clinical Guidelines using the Sage Guideline Workbench and Standard Terminology (James R. Campbell, Samson W. Tu, Karen Hrabak, Mark A. Nyman, Julie Glasgow, Robert McClure)
  
  This tutorial will discuss and demonstrate the SAGE guideline modeling process from beginning to end, starting with a review of the Center for Disease Control (CDC) guideline for immunization practices, and ending with a runtime demonstration of the clinical user view of immunization decision support. Participant interaction and discussion will be encouraged and those interested may develop their own limited guideline model within the casework exercises provided by the tutorial staff. A brief summary of issues related to interpretation of guidelines will be presented, followed by examples of implementation scenario development, summarization of guideline logic creation, and an inventory of decision concept requirements. Mapping and modeling of concepts with SNOMED CT, LOINC and other standard vocabularies will be highlighted. The role of reference terminology features central to clinical decision support functions will be discussed. Development of work context links and decision process modeling will be demonstrated using the Protégé guideline workbench. Validation of the interoperable guideline model using Protégé extension plug-in features will be demonstrated. An execution exemplar will be presented, illustrating the interaction of the SAGE guideline engine with the clinical information system as seen by the clinical user.

• OWL Tutorial I (Alan Rector, Nick Drummond, Matthew Horridge, Hai Wang, Olivier Dameron)
  
  OWL is the W3C standard ontology language for the Semantic Web, and Protégé-OWL the most widely used editing tool for OWL. This beginner's tutorial introduces OWL ontology development with Protégé-OWL and is the "hands-on" version of the Protégé-OWL pizza tutorial. We will explain the basic language elements of OWL (classes, properties and individuals) and show how they can be edited with Protégé-OWL. We will then explore more complex OWL class descriptions by showing how different types of restrictions can be used to enhance the logical meaning of classes, after which we will discuss the important notion of primitive and defined classes. One of the key features of OWL is that it is underpinned by Description Logics, meaning that it has well understood formal semantics. This makes it possible to use a Description Logic reasoner as an aid in constructing an ontology, checking class consistency, and computing an inferred class hierarchy. Attendees will be exposed to this functionality throughout the tutorial, and we will provide a basic introduction to reasoning. More details on reasoning can be acquired in the "Advanced Reasoning with OWL" afternoon tutorial. We will also walk through selected other features of Protégé-OWL, including ontology visualization. Slides from related tutorials can be found on the CO-ODE Web site.

• Advanced Reasoning with OWL (Alan Rector, Nick Drummond, Matthew Horridge, Hai Wang, Olivier Dameron)
  
  The goal of this tutorial is to leverage the reasoning capabilities of OWL. We will rely on the semantics of Description Logics to explain the principles of reasoning by classification. On this base, we will see how the expressivity of OWL constructs can be used (1) to represent knowledge, (2) to organize your concepts by classification, (3) to ensure that the ontology is correct, and (4) to make ontology maintenance easier. This tutorial is intended to be a complement to the basic Protégé-OWL tutorial. The session will mainly rely on hands-on exercises, so the practical aspect will be tackled. The overall message of this tutorial will definitely be about "what to do?" rather than about "where to click?".

• Ontology Visualization with Jambalaya (Chris Callendar)
  
  Jambalaya is a Protégé plug-in for visualizing ontologies. This tutorial will cover the basics of navigating ontologies: browsing concepts, filtering relationships and concepts, using layouts, and showing high level relationships. It will also cover querying ontologies and a quick overview of some of the new features in Jambalaya such as a degree of interest model and use of motion. The target audience for the tutorial are ontology users and developers. The focus will not be on Java programming, but any questions about extending Jambalaya are welcome after the tutorial.

• JessTab Tutorial (Henrik Eriksson)
  
  This tutorial will introduce the JessTab extension, which enables the use of the Java Expert System Shell (Jess) under Protégé. The tutorial will cover basic Jess programming, rule-based reasoning with Jess under Protégé, and the use of Jess for managing Protégé ontologies and knowledge bases. Furthermore, the tutorial will address the mapping of instances in Protégé knowledge bases to Jess facts and use of the JessTab with both Protégé-Frames and Protégé-OWL. The tutorial will exemplify practical uses of Jess together with Protégé and discuss common design patterns. The tutorial will demonstrate how to install Jess and the JessTab and how to interact with the JessTab. The target audience is developers interested in combining ontologies and reasoning. No prior knowledge of Jess or the JessTab is required.

• Application Development with Protégé (Timothy Redmond, Tania Tudorache, Jennifer Vendetti)
  
  This tutorial will address the issue of developing plug-ins and applications with Protégé. It will start with a description of the Protégé Plug-in Framework and describe how the plug-in framework can be used to add capabilities to the Protégé system. We will cover all of the existing plug-in types. We will describe what is necessary to develop each type of plug-in and how each plug-in type extends the Protégé application. We will follow-up the discussion of Protégé plug-ins with a discussion of an alternative paradigm of development in Protégé: the development of standalone Protégé applications. We will see that in many cases, there is a natural evolution from the development of Protégé plug-ins to the development of standalone Protégé applications. We will describe the architectural design issues in application development and analyze some real deployed applications that have been built with Protégé. The target audience includes both Java programmers and non-programmers.

• Ontology Visualization (Jennifer Vendetti)
  
  This tutorial will focus on several Protégé plug-ins that have been developed specifically for the purpose of visualizing ontologies. The first portion of the tutorial will be a hands-on walk-through of the graph widget tutorial that is available on the Protégé Web site. The graph widget is a custom slot widget plug-in that allows users to graphically create and populate instances of classes. It is very useful as a) an alternative to Protégé Forms for entering instance data, b) as a way to visualize networks of instances, and c) as a way to visualize relationships between instances. The second portion of the tutorial will be a demonstration of the Ontoviz and TGViz tab plug-ins. If time permits at the end of the tutorial, there will also be a demonstration of a new visualization plug-in called the Impact & Alignment Tab, which is a work in progress and will be released in the fall. The target audience for this tutorial are Protégé users with little exposure to the existing visualization plug-ins that are currently available. If users plan to follow the hands-on portion of the tutorial, basic experience with navigating the Protégé user interface will be assumed. Attendees should know how to perform rudimentary tasks such as opening projects and creating new classes, slots, and instances.
