Maschinenlesbare und -abrufbare Web Services werden zu Produktionsmodulen in einem globalen 'Factory Floor'. Ihre 'Orchestrierung' erlaubt die standardisierte Bildung von Modulen höherer Ordnung. Die dabei gebildeten Prozesse können die Wahl der einzubindenden Dienste via 'Discovery Agency' optimieren. Das Organisieren von Wertschöpfungssystemen wird damit zur modularen Programmierung im Grossen, der Abruf von Leistungen zum Aufruf und dynamischen Einbinden eines Moduls. Wird damit eine ideale Infrastruktur für die Virtualisierung der Organisationen verfügbar? Wir analysieren den Begriff der Organisation, einerseits aus Informatik-Optik als Multi-Agenten-Systeme, aber auch als soziales Gebilde mit den Begriffen der Institution und des Symbolischen und verbinden sie im Begriff des Mediums. Wir argumentieren, dass der gegenwärtige Stand der Web Services-Protokolle noch zu wenig Struktur für virtuelle Organisationen hat und zeigen, was zu ergänzen ist.

Web 2.0 nimmt in vielen Unternehmen eine zunehmend gewichtigere Rolle in deren aktuellen und künftigen Geschäftsmodellen ein. Dieser Entwicklung entspringt der Begriff „Corporate Web 2.0“, welcher den Einsatz von Web-2.0-Anwendungen im Business-Kontext bezeichnet. Hohe Komplexität und fehlende Strukturen lassen derzeit im Web 2.0 einen systematischen, lernorientierten Vergleich von Business- Cases nur eingeschränkt zu. Die vorgestellte CWeb 2.0 Profile-Map ermöglicht als Schema zur Charakterisierung und Kategorisierung von Web 2.0-Fallbeispielen eine systematische, Businesskontext-abhängige Beschreibung und Kategorisierung. Vergleichbare Anwendungen des Web 2.0 können so besser erkannt und Erfahrungen aus einzelnen Anwendungsfällen über Organisationsgrenzen hinweg effektiver transferiert werden.

Einer der bestimmenden Faktoren moderner Gesellschaften ist die fortlaufende Digitalisierung von Informationen und Resourcen. Dieser Trend spiegelt sich in heutiger Forschung wider und hat starken Einfluss auf akademische und industrielle Projekte. Es ist nahezu unmöglich, ein modernes Projekt aufzusetzen, welches keinerlei digitale Aspekte beinhaltet und viele Projekte werden mit dem alleinigen Zweck der Digitalisierung eines Teils der Welt ins Leben gerufen. Dieser Trend führt zur Entstehung neuer Forschungsfelder an den Schnittstellen zwischen der analogen Welt -- beispielsweise den Geisteswissenschaften -- und der Digitalen -- beispielsweise der Informatik. Eine davon ist das für diese Arbeit interessante Gebiet der Digital Humanities. Dabei werden komplexe Forschungsfragen, -techniken und -prinzipien verbunden, die sich unabhängig voneinander entwickelten. Viel Mühe ist nötig, um die Kommunikation zwischen deren Konzepte zu definieren um Missverständnisse und Fehleinschätzungen zu vermeiden. Dieser Prozess der Brückenbildung ist eine zentrale Aufgabe der neu entstehenden Forschungsfelder. Diese Arbeit schlägt eine solche Brücke für die textorientierten Digital Humanities vor. Diese Lösung basiert auf einem Referenzsystem für digitalen Text, welches in den Geisteswissenschaften spezifiziert und im Rahmen dieser Arbeit zu einem Datenkommunikationsprotokoll für die Informatik uminterpretiert wurde: dem Canonical Text Service (CTS) Protokoll. / One of the defining factors of modern societies is the ongoing digitization of information, resources and in many ways even life itself. This trend is obviously also reflected in today's research environments and heavily influences the direction in which academic and industrial projects are headed. It is borderline impossible to set up a modern project without including digital aspects and many projects are even set up for the sole purpose of digitizing a specific part of the world. One of the side effects of this trend is the emergence of new research fields at the intersection points between the analog world -- represented for example by the humanities -- and the digital world -- represented for example by computer science. One set of such research fields are the digital humanities, the area of interest for this work. In the process of this development, complex research questions, techniques, and principles are aligned next to each other that were developed independently from another. A lot of work has to go into defining communication between the concepts to prevent misunderstandings and misconceptions on both sides. This bridge building process is one of the major tasks that must be done by the newly developed research fields. This work proposes such a bridge for the text-oriented digital humanities based on a digital text reference system that was previously developed in the humanities and is in this work reinterpreted as a data communication protocol for computer science: The Canonical Text Service (CTS) protocol.

Present web is aiming to the possibility of automatization of user behavior on web applications. Adding of semantics and creation of web service interface are the main approaches for accomplishment of this user comfort. Nevertheless, this direction brings some problems which can make more difficult publishing and implementation of web documents. Web services can connect heterogeneous systems, because they are based on XML markup language that is a place where all applications can meet without lost of platform independence. The automatic transformation of a web application into a web service could be considerably more effective than to create a web service from the beginning. However, this step is for some applications almost unreal without knowledge of their inner structure. In most cases, the transformation will be done semiautomatically with help of human decisions.

Over the last years, Web services have become increasingly popular. It is because they allow businesses to share data and business process (BP) logic through a programmatic interface across networks. In order to reach the full potential of Web services, they can be combined to achieve specifi c functionalities. Web services run in complex contexts where arising events may compromise the quality of the system (e.g. a sudden security attack). As a result, it is desirable to count on mechanisms to adapt Web service compositions (or simply called service compositions) according to problematic events in the context. Since critical systems may require prompt responses, manual adaptations are unfeasible in large and intricate service compositions. Thus, it is suitable to have autonomic mechanisms to guide their self-adaptation. One way to achieve this is by implementing variability constructs at the language level. However, this approach may become tedious, difficult to manage, and error-prone as the number of con figurations for the service composition grows. The goal of this thesis is to provide a model-driven framework to guide autonomic adjustments of context-aware service compositions. This framework spans over design time and runtime to face arising known and unknown context events (i.e., foreseen and unforeseen at design time) in the close and open worlds respectively. At design time, we propose a methodology for creating the models that guide autonomic changes. Since Service-Oriented Architecture (SOA) lacks support for systematic reuse of service operations, we represent service operations as Software Product Line (SPL) features in a variability model. As a result, our approach can support the construction of service composition families in mass production-environments. In order to reach optimum adaptations, the variability model and its possible con figurations are verifi ed at design time using Constraint Programming (CP). At runtime, when problematic events arise in the context, the variability model is leveraged for guiding autonomic changes of the service composition. The activation and deactivation of features in the variability model result in changes in a composition model that abstracts the underlying service composition. Changes in the variability model are refl ected into the service composition by adding or removing fragments of Business Process Execution Language (WS-BPEL) code, which are deployed at runtime. Model-driven strategies guide the safe migration of running service composition instances. Under the closed-world assumption, the possible context events are fully known at design time. These events will eventually trigger the dynamic adaptation of the service composition. Nevertheless, it is diffi cult to foresee all the possible situations arising in uncertain contexts where service compositions run. Therefore, we extend our framework to cover the dynamic evolution of service compositions to deal with unexpected events in the open world. If model adaptations cannot solve uncertainty, the supporting models self-evolve according to abstract tactics that preserve expected requirements. / Alférez Salinas, GH. (2013).

New approaches are needed to manage and analyze the enormous quantity of biological data generated by modern technologies. Existing solutions are often fragmented and uncoordinated and, thus, they require considerable bioinformatics skills from users. Three applications have been developed illustrating different strategies to help users without extensive IT knowledge to take maximum profit from their data. SNPator is an easy-to-use suite that integrates all the usual tools for genetic association studies: from initial quality control procedures to final statistical analysis. CHAVA is an interactive visual application for CNV calling from aCGH data. It presents data in a visual way that helps assessing the quality of the calling and assists in the process of optimization. Haplotype Association Pattern Analysis visually presents data from exhaustive genomic haplotype associations, so that users can recognize patterns of possible associations that cannot be detected by single-SNP tests. / Calen noves aproximacions per la gestió i anàlisi de les enormes quantitats de dades biològiques generades per les tecnologies modernes. Les solucions existents, sovint fragmentaries i descoordinades, requereixen elevats nivells de formació bioinformàtica. Hem desenvolupat tres aplicacions que il•lustren diferents estratègies per ajudar als usuaris no experts en informàtica a aprofitar al màxim les seves dades. SNPator és un paquet de fàcil us que integra les eines usades habitualment en estudis de associació genètica: des del control de qualitat fins les anàlisi estadístiques. CHAVA és una aplicació visual interactiva per a la determinació de CNVs a partir de dades aCGH. Presenta les dades visualment per ajudar a valorar la qualitat de les CNV predites i ajudar a optimitzar-la. Haplotype Pattern Analysis presenta dades d’anàlisi d’associació haplotípica de forma visual per tal que els usuaris puguin reconèixer patrons de associacions que no es possible detectar amb tests de SNPs individuals.
