Build Your Mashup with Web Services

Mashup is presenting new kind of application in web 2.0 world. Mashup is not simply about the AJAX technologies, rather, it is typically related to reuse the data and other services from other web side and web applications. There are many ways to build up the mashup. This half-day tutorial will focus on using XML and JSON format of data and service and will introduce the following to the participants:

• What Mashup is about.• The existing Mashup web sites and applications.• The Mashup design and architecture which include the client-side mashups

and server-side mashups.• The existing mashup technologies.• Case Studies by using JSON services (By using Yahoo’s, Google’s and

IBM’s)• Case Studies by using XQuery (IBM DB2 V9) by using existing RSS feeds.At the completion of this tutorial, participants will learn the latest mashup

trends and how to architecture, build and manage the Mashup by using the existing tools, data and services for their applications.

Semantic SOA in Action:A Practical Demonstration

This tutorial is intended for researchers and industry practitioners who are interested in modeling ontologies to support knowledge engineering and management, database modeling, business process modeling and enterprise information integration with a focus on practical demonstration. The tutorial gives a deeper insight for designing of ontologies and conceptual modeling. It talks about solution strategies for global enterprise system which provides unified information and agile solution with greater ease and simplicity. The tutorial also includes demonstration of the concepts using ontology modeling tools. Global enterprise system needs to cater the requirements of a constantly changing environment like business environment changes, user requirement changes and technical environment changes.

Session 4, no 1 Semantics in Web Services

Modeling Web Services using Semantic Graph Transformations to aid Automatic Composition

1 Liu, IBM T.J. Watson Research Center, Hawthorne, NY1 Ranganathan, IBM T.J. Watson Research Center, Hawthorne, NY1 Riabov, IBM T.J. Watson Research Center, Hawthorne, NY

p78

Modeling Web Services using Semantic Graph Transformations to aid Automatic Composition

Main notion is semantic propogation (eg. dependence of output on input), modeled by graph transformations

only for services that do data processing (stateless – at least for now)

instead of using ontolgies as in OWL-S claim it is better for expressing constraints also compared with SAWSDL currently no constraints on state – just input/output used to help connect services as for workflow

Session 4, no 2 Semantics in Web Services

Improved Matchmaking Algorithm for Semantic Web Services Based on Bipartite Graph Matching

1 Bellur, Kanwal Rekhi School of Information Technology, IIT Bombay1 Kulkarni, Kanwal Rekhi School of Information Technology, IIT Bombay

p86

Improved Matchmaking Algorithm for Semantic Web Services Based on Bipartite Graph Matching

Very important/useful background (sect 1+2) explains the discovery process and limitations (sect 1) prev work on semantic matchmaking (sect 1) Paolucci [19]

Semantic Matching of Web Services Capabilities + more outlines OWL OWL-S - use IOPE : Input Output Precond

Effects mentions DL (Description Logic) used by reasoners argues with Palolucci's – exact, plugin, subsume proposes a different algorithm

Session 4, no 3 Semantics in Web Services

Applying Abduction in Semantic Web Service Composition

1 Lecue, Ecole Nationale Superieure1 Delteil, France Telecom R&D, France1 Leger, France Telecom R&D, France

p94

Applying Abduction in Semantic Web Service Composition

background about semantic web services composition

(functional and process) real life example – phone related services composition – check if the output of one service matches input

of next (others do this too) use causal links (from AI planning) matchmaking – similar basis Paolucci

Semantic Matching of Web Services Capabilities use concept abduction from [11] Tommaso Di Noia, Eugenio Di

Sciascio, Francesco M. Donini, Marina Mongiello: Abductive Matchmaking using Description Logics. IJCAI 2003: 337-342

Session 6, no 1Quality of Service and Security

Probabilistic QoS and soft contracts for transaction based Web services

1 Rosario, IRISA/INRIA1 Benveniste, IRISA/INRIA1 Haar, University of Ottawa, Canada1 Jard, ENS Cachan Bretagne, France

P126

Probabilistic QoS and soft contracts for transaction based Web services

mentions orchestration using contract compositions [6, 3] for the functional part search

but deals with QoS for such compositions. mentions WSLA (Web Service Level Agreement) – proposed by IBM [12]

most others deal with hard bounds of eg. response time, availability, thruput, security (the paper does not deal with security)

they explain why hard bounds are not good enough – in practice need "quantiles" eg. 95% of queries answered in less than 5 msec

Probabilistic QoS and soft contracts for transaction based Web services (cont.)

here they propose a fully probabilistic approach (distribution rather than quantiles) for better composition

combine the functional + QoS contracts, need to be able express concurrency/sequenalization of

orchestration exactly – use math model eg. WFnets use eg. ORC Misra [23] an academic language for

orchestration Jayadev Misra and William R. Cook Computation Orchestration A Basis for Wide-Area Computing also see ORC web site

use monte carlo simulations survey QoS enabled composition (sect II) Their tool TOrQuE, examples

Session 7, no 1 Autonomic Web Service Platform Technology

Automatic Composition of SemanticWeb Services 1 Kona, University of Texas at Dallas1 Bansal, University of Texas at Dallas1 Gupta, University of Texas at Dallas

p 150

Automatic Composition of SemanticWeb Services

need a semantics based approach to make services accessible by applications rather than humans

mentions effort to built infrastructure for service discovery, composition etc [17,23,15] –

some are based on semantic web (USDL, OWL-S, WSML, WSDL-S) others on XML (WSDL) – purely syntactic

discovery – if a service is not found, try to find 2 or more that may be composed to synthesize it – a composition

the paper gives (the first?) precise defintion of dicovery and composition, an algorithm, and a prootype implementation

based on constraint logic programming

Session 7, no 3 Autonomic Web Service Platform Technology

A protocol for QoS contract negotiation and its implementation using Web Services

p 168

Session 8, no 1Web Services Integration

Rich Services: The Integration Piece of the SOA Puzzle

1 Arrott, University of California, San Diego1 Demchak, University of California, San Diego1 Errnagan, University of California, San Diego1 Farcas, University of California, San Diego1 Farcas, University of California, San Diego1 Kriiger, University of California, San Diego1 Menarini, University of California, San Diego

p 176

Rich Services: The Integration Piece of the SOA Puzzle

Why Corba did not deliver? tight coupling, heavy weight of tightly integrating all concerns as all encompassing middleware

WS – separation of concern. result – fragmentation of concerns. challenge: how to integrate the pieces of the puzzle

back into coherent picture, for enterprise scale SOAs. Introduce Rich Services – basically an architecture

Session 10, no 1 Context-Aware Web Services Discovery

Handling User Preferences and Added Value in Discovery of Semantic Web Services

1 Kovacs, MTA SZTAKI, Computer and Automation Research Institute1 Micsik, MTA SZTAKI, Computer and Automation Research Institute1 Pallinger, MTA SZTAKI, Computer and Automation Research Institute

p 225

Handling User Preferences and Added Value in Discovery of Semantic Web Services

A discovery engine first phase – traditional information retreival (keyword

matching) pre-filtering second phase - logic based matching, in prolog. novel prolog style unification of terms Semantic Web still lacks mechanism for preference

based querying. (Owl-S, based on Description Logic). match between user goal and web service definition use Disjunctive Normal Form. count number of matched terms. part of a EU project INFRAWEBS

Session 11, no 1 Web Services Indexing and Discovery

Reputation-Enhanced QoS-based Web Services Discovery 1 Xu, Queen's University, Kingston, ON, Canada1 Martin, Queen's University, Kingston, ON, Canada1 Powley, Queen's University, Kingston, ON, Canada1 Zulkernine, Queen's University, Kingston, ON, Canada

p 249

Reputation-Enhanced QoS-based Web Services Discovery

QoS important when several services provide similar functionality

UDDI registers cannot provide QoS info. Authenticity of QoS available info may be questionable The paper proposes extended UDDI, with QoS, and a

reputation management system. Some previous work on the use of reputation info reputation score. less recent data maybe less/more

significant. Some experiments

Session 11, no 3 Web Services Indexing and Discovery

Web Service Discovery Using General-Purpose Search Engines1 Song, Samsung Information System America1 Cheng, Samsung Information System America1 Messer, Samsung Information System America1 Kalasapur, Samsung Information System America

p 265

Web Service Discovery Using General-Purpose Search Engines

used yahoo and google to search for web services.

yahoo and google were not designed for this, so try specific approaches (eg. use service name and/or port type and/or operation names, with/without additional annotations)

results of experiments . eg. embedding WSDL into web page enabled both search engines to find it

Session 13, no 1Web Services Composition

BPEL4Chor: Extending BPEL for Modeling Choreographies

1 Decker, University of Potsdam, Germany1 Kopp, University of Stuttgart, Germany1 Leymann, University of Stuttgart, Germany1 Weske, University of Potsdam, Germany

p 296

BPEL4Chor: Extending BPEL for Modeling Choreographies

BPEL (Business Process Execution Language) is a language to orchastrate web services into a single business process.

In choreography, several processes are interconnected & interaction behavior described from global perspective.

The paper extends BPEL to define choreography.– Participant behavior: control flow dependencies– Participant topology: exisiting participants and their interconnection

using message links– Participant grounding: concrete configuration for data format and

port types Seamless integration between orchatration and

choreography

Session 14, no 1 Web Services Modeling and Tooling

Model-driven Composition of Context-aware Web Services Using ContextUML and Aspects1 Prezerakos, Technological Education Institute1 Tselikas, National Technical University of Athens1 Cortese, Universita' di Roma Tor Vergata

p 320

Model-driven Composition of Context-aware Web Services Using ContextUML and Aspects

to match user expectations, services should exhibit some context awareness

but in a of composite service, the context may have to change.

core service functionality should be separate from context handling, which cross cut into it.

A proposed solution by Model Driven approach for design, and AOP for coding.
