SPARQL -- Where are we? Current state, theory and practice [Full-day Tutorial] Presenters: Marcelo Arenas, Claudio Gutierrez, Bijan Parsia, Jorge Pérez, Axel Polleres, and Andy Seaborne Abstract: After the data and ontology layers of the Semantic Web stack have achieved considerable stability through standards such as RDF and OWL, the query layer, realized by SPARQL, is the next item on W3C's agenda. Short before its completion, we will take the opportunity to reflect on the current state of the language, its applications, recent results on theoretical foundations, but also future challenges. This tutorial will teach SPARQL along two complementary streams: On the one hand we will provide a practical introduction for newcomers, giving examples from various application domains, providing formal underpinnings and guiding attendees through the jungle of existing implementations, including those which reach beyond the current specification to query more expressive Semantic Web languages than RDF. On the other hand, we will go further into depth of theoretical foundations of SPARQL, presenting recent results of SPARQL's complexity, formal foundations in terms of database theory, as well as its exact semantic relation to the other building blocks in the SW stack, namely, RDF Schema, OWL and the rules layer. Finally, we aim to bring these two streams together, and will identify the current limitations and challenges around SPARQL, pointing to possible extensions and emerging application fields.

These technologies include metadata management, semantic search and browsing, personalized and community-aware services, and semantically empowered federations of digital libraries. The semantic digital libraries can be used in enterprise scale systems such as knowledge management systems, medical records systems, legal research systems and others will be discussed at some depth. These applications can benefit in manners which directly impact the ROI for the effort of including semantic encoding and metadata into an enterprise's digital library based systems and services. After this tutorial, the audience will be able to start using existing semantic digital libraries or apply Semantic Web technologies to digital library systems. We will start by defining problems in the domain of semantic digital libraries and present solutions that provide building blocks for semantic digital libraries, such as WordNet, DMoz, and SKOS. We will then present the architecture of existing semantic digital libraries, elaborate on resource management, search and browsing features, identity management and communication interfaces. We will discuss in detail the problems and solutions for bibliographic metadata management and interoperability, followed by a presentation of semantic search and browsing solutions, and other personalized and community-aware services. We will discuss the future of federations of digital libraries in the context of the Semantic Web and Web 2.0 Internet.

We present the state of the art in both areas (process modeling and execution in BPM, the SOA concept in BPM, the SWS approach and frameworks, etc.), motivate the need for explicit use of semantics to overcome the current challenges in BPM, and present a consolidated technical framework that integrates SWS into BPM technology. The tutorial will be held as a full day event. The morning session covers the foundations and theoretical aspects, while the afternoon is dedicated to a comprehensive hands-on session wherein the attendees actively model Business Processes and Semantic Web Services with respective software tools. Therewith attendees will gain a comprehensive overview of the latest developments in semantically enriched BPM technology, which is one of the central trends in BPM research and development. The tutorial is held by BPM and SWS experts that actively work on integration of both technologies in the EU-funded SUPER project (homepage: http://ip-super.org/).

Lisi, Dipartimento di Informatica, Università degli Studi di Bari, Italy. Abstract: Ontology and rule languages for the Semantic Web are logically founded on fragments of first-order logic, namely Description Logics (DLs) and hybrid DL-Horn Clausal Logics. Building ontologies as well as rules on top of ontologies is a very demanding task also from the Knowledge Acquisition viewpoint. When performing this task, Semantic Web practitioners could take benefit from the application of Machine Learning (ML) methods and techniques. The ML approach known as Inductive Logic Programming (ILP) seems to be particularly appropriate due to the common roots with computational logic. The tutorial on "Inductive Logic Programming Approaches to Ontology and Rule Acquisition for the Semantic Web" will provide a survey of ILP proposals for learning with DLs and hybrid DL-Horn Clausal Logics. Attendees are expected to be knowledgeable in (quasi-)standard languages for ontologies and rules for the Semantic Web (OWL and SWRL) and to have basic notions of first-order logic. The tutorial will focus mainly on theoretical aspects but the presentation will be rich in illustrative examples, animations, etc. in order to assure that the attendees become acquainted with the logical foundations of ontology and rule languages and fully comprehend the potential of ILP for the Semantic Web.

The tutorial will give an overview of problems and requirements of semantic annotation and will present state-of-the-art methods, such as manual annotation, authoring of documents, semi-automatic annotation and deep annotation, as well as applications of annotations such as linguistic, service and multimedia annotation. We will give an overview of annotation tools and systems, followed by a closer look at the evaluation issues. In the 2007 edition of this tutorial, which will be driven by examples and demonstrations, we will focus on the Semantic Annotation of multimedia material, as the challenge for the semantic web here is even bigger as for textual data on the web: How to bridge the Semantic Gap of the human interpretation of images and videos and the low-level descriptors which capture the results of multimedia analysis.

Successfully managing knowledge means being able to provide the right information at the right time to the right person. As the size and number of such archives is growing and large organizations become geographically distributed, the sharing of knowledge becomes more and more complex. Traditional models based on centralized archives are becoming largely inadequate solutions. In this tutorial I will describe and discuss the challenge of managing knowledge in large organizations and the way Semantic Web technologies can be used to support the acquisition, sharing and reuse of knowledge, integrating more traditional methods in order to provide effective management of knowledge. The tutorial will draw examples from real use cases and will present cases of successful deployment of semantic web technologies.

This tutorial presents the state of the art in representing and reasoning with uncertain and/or vague knowledge in the Semantic Web. The goal of the tutorial is to make attendees familiar with the concepts and techniques for representing and reasoning with uncertain and vague knowledge in Semantic Web ontology and rule languages, such as RDF, OWL, RuleML, and SWRL, which will help the attendees to gain insights on the main features of the formalisms and tools proposed so far. The tutorial requires no specific prerequisite knowledge, except for basic knowledge in first-order logic. It will start by introducing basic characteristics and observations on the Semantic Web, and the technical details will be self-contained.
