Tutorial III: Open Data and Semantic Technology
Speaker: Prof. Dr. Sören Auer, University of Bonn and Fraunhofer IAIS, Germany
Date: November 9, 2014 Time: 13.00-16.00 Room: Doi Suthep 1

Abstract:

In this tutorial, we will discuss the characteristics and benefits of semantic data integration as well as key standards such as RDF, RDF-Schema and SPARQL. We will look into tools for extracting, authoring, querying and linking of data. We will further discuss large scale applications of semantic technologies such as enterprise data integration, DBpedia knowledge extraction and Governmental Open Data Portals.

Tutorial II: Description Logic Reasoning for Semantic Web Ontologies

Speaker:  Dr. Anni-Yasmin Turhan, Dresden University of Technology, Germany
Date: November 9, 2014 Time: 09.00-12.00 Room: Doi Suthep 2

Abstract:

Description Logics (DLs) are a successful family of logic-based knowledge representation formalisms, which can be used to represent the conceptual knowledge of an application domain in a structured and formally well-understood way. Based on their formal semantics, a number of powerful DL reasoning services have been defined and are implemented in optimized reasoner systems. Formal ontology languages for the Semantic Web such as OWL 2 and its profiles have greatly increased interest in DLs and related reasoning services in recent years. Most of these ontology languages are based on DLs. This tutorial gives an introduction to the basic notions underlying knowledge representation and reasoning with DLs. The main focus is on those DLs that form the core of the OWL lightweight profiles and the reasoning services they are tailored for.

Anni-Yasmin Turhan is an adjunct professor at Technische Universität Dresden. After obtaining her Diploma in Computer Science, she started her scientific career in a research project on non-standard inferences in Description Logics. Her research interests are reasoning under vagueness and similarity. In her post-doc years she was a key researcher in several research projects on situation recognition by Description Logics reasoning. Earlier in this year she had completed her postdoctoral degree on maintenance and flexible access to description logic ontologies.

Tutorial I: Ontology Building and its Application using Hozo

Speaker: Dr. Kouji Kozaki, I.S.I.R., Osaka University, Japan
Date: November 9, 2014 Time: 09.00-12.00 Room: Doi Suthep 1

Abstract:

Hozo (http://www.hozo.jp) is an environment for building/using ontologies based on ontological theory of role [1]. It provides sophisticated user interfaces with some characteristic functions such as dynamic is-a hierarchy generation [2] and divergent ontology exploration [3] so that the users can build well-organized ontologies according to appropriate viewpoints. Various ontologies and ontology-based applications are developed built using Hozo and its API.

This tutorial introduces how to build ontologies using Hozo with basic theories of ontological engineering. Then, I explain techniques to develop ontology-based application using Hozo API with some example applications.

Tutorial IV: Constructing and Understanding Knowledge Graph

Speaker: Dr. Jeff Z. Pan, University of Aberdeen, UK
Date: November 9, 2014 Time: 13.00-16.00 Room: Doi Suthep 2

Abstract: 

The benefits and potentials of Linked Data (LD) have been utilised and demonstrated by numerous applications from academic, industry and public sectors. This explains the recent vast increase of LD not only in data volume but also in number of datasets and related domains. However, consuming a linked dataset requires technical background of Semantic Web (SW) techniques and the knowledge of the dataset. Direct use of such valuable knowledge space is very time consuming and is still a privilege of SW "geeks". In this tutorial, we propose the vision of converting LD into knowledge graphs which are not only capable to enhance accessibilities in LD consumption but also enable LD directly usable to end users. Specifically, this tutorial consists of two parts. The first part will introduce the overview, applications and research challenges to create knowledge graphs on top of LD. The second part will focus on specific techniques for knowledge graph, including knowledge graph construction and knowledge graph understanding.

He joined the faculty in the Department of Computing Science at University of Aberdeen in 2005. He is now the Deputy Director of Research of the department. His research focuses primarily on knowledge representation and reasoning, in particular scalable ontology reasoning, querying and reuse, and their applications (such as Semantic Web, Advertising, Healthcare, Software Engineering and Multimedia). He is a key contributor to the W3C OWL2 standard. He leads the work of the TrOWL Tractable OWL2 reasoning infrastructure. He is widely recognised for his work on scalable and efficient ontology reasoning; he gave tutorials on this topic in e.g. AAAI2010, ESWC2010, ESWC2011, SemTech2011 and the Reasoning Web Summer School (2010 and 2011).
