An Answer Set Programming Tutorial

Minh Dao Tran

Vienna University of Technology (TU Wien)

Abstract

Answer Set Programming (ASP) is a declarative problem solving paradigm, rooted in Logic Programming and Nonmonotonic Reasoning, which has been gaining increasing attention during the last years. In this tutorial I will start with the basic notions on positive logic program,

stable model semantics, then mention extensions such as constraints,
disjunction, and present recent results regarding using ASP for
Reasoning in the Semantic Web. Finally, we can play with ASP on some
simple examples.

An Introduction to Presence in the Enterprise: Protocols and Deployments

Owen Friel

CISCO

Abstract

This tutorial gives overviews of SIP and XMPP protocols and
shows how these protocols are used to enable enterprise presence
systems

Bio: Owen Friel

Mr. Owen Friel is a Technical Leader at Cisco since 2007. His role involves providing technical leadership and architectural direction to the development and deployment of the Cisco Unified Presence server. He is also Policy Architect responsible for integration of Cisco’s Enterprise Policy Manager with the broader Unified Communications Portfolio. Prior to joining Cisco, he was IMS Network Architect with eircom. This role involved defining eircom’s service network evolution strategy from closed PSTN to an open Next Generation Network IMS network. Previous experience includes Principal Engineer at Corvil, a startup developing a Linux based network appliance which provided statistical guarantees for IP network QoS; and 10 years in Nortel working on their Enterprise VoIP and Customer Contact portfolios. He holds an M.Eng.Sc. in speech recognition and neural networks (1995) and a B.E. (1992) in Electronic Engineering from National University of Ireland, Galway.

Introduction to Peer-to-Peer Networks

Manfred Hauswirth, Marcel Karnstedt

Abstract

Peer-to-peer (P2P) systems offer an architectural alternative for global-scale distributed information systems and applications. By taking advantage of the principle of resource sharing, i.e., integrating the resources available at end-user computers into a larger system, it is possible to build applications that scale to a global size. Peer-to-peer systems are decentralized systems in which each participant can act as a client and as a server and can freely join and leave the
system. This autonomy avoids single-point-of-failures and provides scalability but implies considerably higher complexity of algorithms and security policies. The success of the P2P idea has created a huge diversity of approaches, among which overlay networks, for example, Gnutella, Kazaa, Chord, Pastry, Tapestry, P-Grid, or DKS, have received specific attention from both developers and researchers. A wide variety of algorithms, data structures, and architectures have been proposed. In this tutorial we will provide an overview of P2P approaches and several specific applications of large-scale P2P data management. The tutorial is intended to allow researchers and users to assess the properties of concrete systems and their applicability for certain application types.

Introduction to SOA

Sami Bhiri

Abstract

Service Oriented Architecture has received significant attention within academia and industrial communities. Such interest has led to a proliferation of many conflicting definitions of SOA. In this tutorial we present the OASIS reference model which defines an abstract and common framework for understanding significant entities and
relationships between them within a service-oriented environment [1]. We then present two implementations of SOA namely Web services (a.k.a WS-*) and REST services. We show how they implement the OASIS reference model and we draw a comparison between these two implementations.

Introduction to IR

Colm O'Riordan

Abstract

This tutorial will present an introduction to the domain of information retrieval. Topics covered will include introduction to information retrieval models (Boolean, vector space, extensions), pre-processing techniques, metrics for evaluation, weighting schemes (heuristics, axiomatic approaches) and a series of short introductions to a range of subfields including, but not limited to, collaborative filtering, distributed information retrieval and information visualisation.
