Identifying and Modelling Complex Workflow Requirements in Web Applications
Workflow plays a major role in nowadays business and therefore its
requirement elicitation must be accurate and clear for achieving the solution
closest to businessâs needs. Due to Web applications popularity, the Web is becoming
the standard platform for implementing business workflows. In this
context, Web applications and their workflows must be adapted to market demands
in such a way that time and effort are minimize. As they get more popular,
they must give support to different functional requirements but also they
contain tangled and scattered behaviour. In this work we present a model-driven
approach for modelling workflows using a Domain Specific Language for Web
application requirement called WebSpec. We present an extension to WebSpec
based on Pattern Specifications for modelling crosscutting workflow requirements
identifying tangled and scattered behaviour and reducing inconsistencies

Semantic Technologies for Manuscript Descriptions â Concepts and Visions
The contribution at hand relates recent developments in the area of the World Wide
Web to codicological research. In the last number of years, an informational extension
of the internet has been discussed and extensively researched: the Semantic Web. It
has already been applied in many areas, including digital information processing of
cultural heritage data. The Semantic Web facilitates the organisation and linking of
data across websites, according to a given semantic structure. Software can then process
this structural and semantic information to extract further knowledge. In the area
of codicological research, many institutions are making efforts to improve the online
availability of handwritten codices. If these resources could also employ Semantic
Web techniques, considerable research potential could be unleashed. However, data
acquisition from less structured data sources will be problematic. In particular, data
stemming from unstructured sources needs to be made accessible to SemanticWeb tools
through information extraction techniques. In the area of museum research, the CIDOC
Conceptual Reference Model (CRM) has been widely examined and is being adopted
successfully. The CRM translates well to Semantic Web research, and its concentration
on contextualization of objects could support approaches in codicological research.
Further concepts for the creation and management of bibliographic coherences and
structured vocabularies related to the CRM will be considered in this chapter. Finally, a
user scenario showing all processing steps in their context will be elaborated on
Twelve Theses on Reactive Rules for the Web
Reactivity, the ability to detect and react to events, is an
essential functionality in many information systems. In particular, Web
systems such as online marketplaces, adaptive (e.g., recommender) systems,
and Web services, react to events such as Web page updates or
data posted to a server.
This article investigates issues of relevance in designing high-level programming
languages dedicated to reactivity on the Web. It presents
twelve theses on features desirable for a language of reactive rules tuned
to programming Web and Semantic Web applications
Complete Semantics to empower Touristic Service Providers
The tourism industry has a significant impact on the world's economy,
contributes 10.2% of the world's gross domestic product in 2016. It becomes a
very competitive industry, where having a strong online presence is an
essential aspect for business success. To achieve this goal, the proper usage
of latest Web technologies, particularly schema.org annotations is crucial. In
this paper, we present our effort to improve the online visibility of touristic
service providers in the region of Tyrol, Austria, by creating and deploying a
substantial amount of semantic annotations according to schema.org, a widely
used vocabulary for structured data on the Web. We started our work from
Tourismusverband (TVB) Mayrhofen-Hippach and all touristic service providers in
the Mayrhofen-Hippach region and applied the same approach to other TVBs and
regions, as well as other use cases. The rationale for doing this is
straightforward. Having schema.org annotations enables search engines to
understand the content better, and provide better results for end users, as
well as enables various intelligent applications to utilize them. As a direct
consequence, the region of Tyrol and its touristic service increase their
online visibility and decrease the dependency on intermediaries, i.e. Online
Travel Agency (OTA).Comment: 18 pages, 6 figure
BPM News - Folge 3
Die BPM-Kolumne des EMISA-Forums berichtet ĂŒber aktuelle Themen, Projekte und Veranstaltungen aus dem BPM-Umfeld. Schwerpunkt der vorliegenden Kolumne bildet das Thema Standardisierung von Prozessbeschreibungssprachen und -notationen im Allgemeinen und BPEL4WS (Business Process Execution Language for Web Services) im Speziellen. Hierzu liefert Jan Mendling von der WirtschaftsuniversitĂ€t Wien in aktuelles Schlagwort. Des weiteren erhalten Leser eine Zusammenfassung zweier im ersten Halbjahr 2006 veranstalteten Workshops zu den Themen âFlexibilitĂ€t prozessorientierter Informationssystemeâ und âKollaborative Prozesseâ sowie einen BPM Veranstaltungskalender fĂŒr die 2. JahreshĂ€lfte 2006
10. InteruniversitÀres Doktorandenseminar Wirtschaftsinformatik Juli 2009
Begonnen im Jahr 2000, ist das InteruniversitĂ€re Wirtschaftsinformatik-Doktorandenseminar mittlerweile zu einer schönen Tradition geworden. ZunĂ€chst unter Beteiligung der UniversitĂ€ten Leipzig und Halle-Wittenberg gestartet. Seit 2003 wird das Seminar zusammen mit der Jenaer UniversitĂ€t durchgefĂŒhrt, in diesem Jahr sind erstmals auch die Technische UniversitĂ€t Dresden und die TU Bergakademie Freiberg dabei. Ziel der InteruniversitĂ€ren Doktorandenseminare ist der ĂŒber die eigenen Institutsgrenzen hinausgehende Gedankenaustausch zu aktuellen, in Promotionsprojekten behandelten Forschungsthemen. Indem der Schwerpunkt der VortrĂ€ge auch auf das Forschungsdesign gelegt wird, bietet sich allen Doktoranden die Möglichkeit, bereits in einer frĂŒhen Phase ihrer Arbeit wichtige Hinweise und Anregungen aus einem breiten Hörerspektrum zu bekommen. In den vorliegenden Research Papers sind elf BeitrĂ€ge zum diesjĂ€hrigen Doktorandenseminar in Jena enthalten. Sie stecken ein weites Feld ab - vom Data Mining und Wissensmanagement ĂŒber die UnterstĂŒtzung von Prozessen in Unternehmen bis hin zur RFID-Technologie. Die Wirtschaftsinformatik als typische Bindestrich-Informatik hat den Ruf einer thematischen Breite. Die Dissertationsprojekte aus fĂŒnf UniversitĂ€ten belegen dies eindrucksvoll.
Personalizable Service Discovery in Pervasive Systems
Today, telecom providers are facing changing challenges.
To stay ahead in the competition and provide market
leading offerings, carriers need to enable a global ecosystem of
third party independent application developers to deliver converged
services. This is the aim of leveraging a open standardsbased
service delivery platform. To identify and to cope with
those challenges is the main target of the EU funded project
IST DAIDALOS II. And a central point to satisfy the changing
user needs is the provision of a well working, user friendly and
personalized service discovery. This paper describes our work
in the project on a middleware in a framework for pervasive
service usage. We have designed an architecture for it, that
enables full transparency to the user, grants high compatibility
and extendability by a modular and pluggable conception and
allows for interoperability with most known service discovery
protocols. Our Multi-Protocol Service Discovery and the Four
Phases Service Filtering concept enabling personalization should
allow for the best possible results in service discovery
