International Workshop on Web Quality - WQ 2004
Munich, Germany
27 July 2004
http://www.elet.polimi.it/conferences/wq04/
Held in conjunction with
ICWE 04 - International Conference on Web Engineering

Rationale and Aims
Modern Web applications are complex distributed systems that use the
Web as their interaction means and the Internet as their
communication infrastructure. Web applications allow users to
navigate to retrieve information they need and use a wide variety of
services that are now fundamental for an increasing number of
business processes.
The interaction of hypertextual information repositories and
business models is turning Web applications into unique information
systems where the navigational aspects demand usability, user-
friendliness, and robustness, while the application logic requires
correctness and reliability. In general, a number of different
qualities need to be taken into account. What makes Web quality (WQ)
unique is the mix of aspects of Web applications, coming from the
two different domains, namely hypermedia applications and
distributed systems, and the fact that Web applications may be used
by classes of users that are not easy to identify clearly
beforehand. Thus, it is necessary to carefully study, define,
combine, and use the many quality dimensions that characterize Web
applications and their indicators. In addition, it is necessary to
study the influence of these quality dimensions on specific
attributes of the Web application development processes such as
development effort and time, which have a fundamental impact on the
economically successful building of Web applications.
The goal of the International Workshop on Web Quality (WQ 2004) is
to provide a forum to discuss the various aspects of Web quality and
the deployment of quality applications and services. In addition, WQ
2004 will address the study of the quality models underlying the
fundamental approaches, and the investigation of the relationships
between the qualities of the Web products and those of the Web
processes.
The workshop is an opportunity for the communities that work on the
assessment and improvement of the quality of Web applications to
meet and share their knowledge to set appropriate theoretical
foundations, define special-purpose methodologies, and develop
supporting technology. The workshop also aims at promoting research
directions on Web quality engineering by providing a forum where
academic and industrial researchers can share and disseminate ideas.
The workshop aims at hosting significant, high-quality contributions
in all topics related to Web quality engineering, with the goal of
letting participants gain insights into the current state of the art
and future challenges, create synergies through integration, and
foster cross-cooperation.
Covered Topics

eValid: Latest News and Information
Here's a roundup of the latest news from eValid...
New Save-Data Commands
eValid has introduced a new series of commands that involve Saving
Data To Files during eValid playback.
An important addition to this set of commands is the SaveFullHTML
Command that exposes the Complete HTML used internally by eValid.
This feature should allow users of eValid's Interactive Mode
increased power and flexibility in controlling sophisticated
playback activity. There's a full description of these commands at:
http://www.soft.com/eValid/Products/Documentation.40/Interactive/current.page.html
New Dashboard Convenience Features
To increase user convenience we have added direct connections from
eValid's Dashboard to the eValid settings, to eValid's on-line
documentation, and to eValid's cache manager. These new features
saves steps and saves time! Take a look at:

German Version of "WebSite Quality Challenge"
We are pleased to offer a translation of WebSite Quality Challenge
into German: Qualitat von Webprasenzen -- Eine Herausforderung,
translated by our eValid business partner Dr. Jurgen Pitschke, BCS,
Germany. Read the paper:
http://www.soft.com/eValid/Technology/White.Papers/WebSiteQualityChallenge_German.pdf
OnePage Benchmark Comparison Results
The idea that you really need to assess performance at the user's
desk-top -- the "last mile" of the web connection -- is a very good
one.
But we've been worried for some time that companies using well-
known, highly publicized performance benchmarks may be getting less
than complete information. For example, the download time measured
at an ISP using HTTP/S checks from a PERL script will vary
drastically from that measured within eValid running on a DSL and
including full page rendering time.
If you rely on those numbers you may be getting a false impression.
In fact, in our recent experiments we found from ~3:1 up to ~8:1
differences between our measured full page download times and
others' timings.
The OnePage Benchmark Summary Report can be read at:
http://www.soft.com/eValid/Benchmarks/OnePage/summary.html
Our comparisons between eValid data and similar measurements done
with different technology is given at:
http://www.soft.com/eValid/Benchmarks/OnePage/comparison.html
JavaScript Interface Available
We've added a JavaScript interface to eValid. This new interface
provides a convenient way to:
- Issue a JavaScript function call from within the eValid script
file for immediate execution.
- Issue an eValid command from within the JavaScript on a current
page.
The aim is to enhance the operation of eValid in complex
applications that require interaction between the script that is
currently playing and the web pages currently in the eValid browser.

Second International Web Services Quality Workshop (WQW 2004)
Held in conjunction with the
Fifth International Conference on
Web Information Systems Engineering (WISE 2004)
22-24 November 2004, Brisbane, Australia
Aims and Scope
Web services have emerged as a key technology for rendering services
over the WWW. They are interoperable across platforms and neutral to
languages, which makes them suitable for access from heterogeneous
environments. As a consequence of the rapid growth of web service
applications and the abundance of service providers, the consumer is
faced with the inevitability of selecting the "right" service
provider. In such scenarios, the quality of service (QoS) becomes a
benchmark to differentiate services and providers. Quality of
service forms the underpinning for a broad spectrum of web service
activities such as selection, scheduling, pricing and specifying
service level agreements.
This workshop seeks to provide an international forum for discussion
and disseminating of research in the area of web services quality.
Quality is a vital and integral component for the success of the web
services paradigm. The workshop will focus on a holistic view of
quality that integrates the objective view of QoS in terms of
metrics and the subjective perception of QoS in terms of user
context awareness.
The workshop aims to foster and facilitate discussion and
collaboration amongst researchers in the area of web services
quality. The topics for which submissions are solicited include (but
are not limited to):
* Definition of quality metrics
* Automation and validation of web services quality metrics
* Modelling of web services quality
* Quality aware enhancements to UDDI Instrumentation of Web services for QoS
* Agent-based web service architecture as a means of providing QoS attributes
* QoS in grid-based services
* Computation of web processes QoS based on web services QoS
* Semantic description of Web services QoS
* Integration of context-awareness in to web service quality specification
* Estimation and prediction of QoS levels
* Scheduling techniques to support differentiated QoS levels
* QoS driven selection and composition
* QoS driven costing and pricing of web services
* Automated generation of Service Level Agreements from QoS specifications
* Multi-level quality descriptions for web services
* QoE (Quality of Experience) and QoBiz (Quality of Business)
