Technologische Analysen im Umfeld Sozialer Netzwerke

Die vorliegende Arbeit analysiert die Möglichkeiten einer Daten- und Kontaktaggregation im Umfeld Sozialer Netzwerke. Zunächst wird eine Kategorisierung der wichtigsten Netzwerke und Frameworks vorgenommen. Die Funktionalitäten von acht Sozialen Netzwerken und fünf Frameworks werden anhand einer zuvor entwickelten Evaluierungsmatrix detailliert untersucht. Dabei stehen insbesondere die Funktionalitäten der APIs im Vordergrund. Aufbauend auf den Ergebnissen der Analyse wird ein Prototyp für eine Daten- und Kontaktaggregation konzipiert, implementiert und evaluiert. Abschließend werden Empfehlungen zu den verwendeten Technologien und für die Konzipierungen von zukünftigen Daten- und Kontaktaggregationen im Umfeld Sozialer Netzwerke gegeben.This thesis analyses the potential of a data- and contactaggreation in the context of social networks. It provides an overview and categorization of the most important networks and frameworks. The functions of eight social networks and five frameworks are analyzed on the basis of a previously developed matrix of evaluation. Special attention is paid to the features of the APIs. Using the results from the evaluation a prototype is planned, coded and evaluated. Finally, regards for future aggregations between social networks are elaborated

Knowledge-base and techniques for effective service-oriented programming & management of hybrid processes

Recent advances in Web 2.0, SOA, crowd-sourcing, social and collaboration technologies, as well as cloud-computing, have truly transformed the Internet into a global development and deployment platform. As a result, developers have been presented with ubiquitous access to countless Web-services, resources and tools. However, while enabling tremendous automation and reuse opportunities, new productivity challenges have also emerged: The exploitation of services and resources nonetheless requires skilled programmers and a development-centric approach; it is thus inevitably susceptible to the same repetitive, error-prone and time consuming integration work each time a developer integrates a new API. Business Process Management on the other hand were proposed to support service-based integration. It provided the benefit of automation and modelling, which appealed to non-technical domain-experts. The problem however: it proves too rigid for unstructured processes. Thus, without this level of support, building new application either requires extensive manual programming or resorting to homebrew solutions. Alternatively, with the proliferation of SaaS, various such tools could be used for independent portions of the overall process - although this either presupposes conforming to the in-built process, or results in "shadow processes" via use of e-mail or the like, in order to exchange information and share decisions. There has therefore been an inevitable gap in technological support between structured and unstructured processes. To address these challenges, this thesis deals with transitioning process-support from structured to unstructured. We have been motivated to harness the foundational capabilities of BPM for its application to unstructured processes. We propose to achieve this by: First, addressing the productivity challenges of Web-services integration - simplifying this process - whilst encouraging an incremental curation and collective reuse approach. We then extend this to propose an innovative Hybrid-Process Management Platform that holistically combines structured, semi-structured and unstructured activities, based on a unified task-model that encapsulates a spectrum of process specificity. We have thus aimed to bridge the current lacking technology gap. The approach presented has been exposed as service-based libraries and tools. Whereby, we have devised several use-case scenarios and conducted user-studies in order to evaluate the overall effectiveness of our proposed work

Digital Classical Philology

The buzzwords “Information Society” and “Age of Access” suggest that information is now universally accessible without any form of hindrance. Indeed, the German constitution calls for all citizens to have open access to information. Yet in reality, there are multifarious hurdles to information access – whether physical, economic, intellectual, linguistic, political, or technical. Thus, while new methods and practices for making information accessible arise on a daily basis, we are nevertheless confronted by limitations to information access in various domains. This new book series assembles academics and professionals in various fields in order to illuminate the various dimensions of information's inaccessability. While the series discusses principles and techniques for transcending the hurdles to information access, it also addresses necessary boundaries to accessability.This book describes the state of the art of digital philology with a focus on ancient Greek and Latin. It addresses problems such as accessibility of information about Greek and Latin sources, data entry, collection and analysis of Classical texts and describes the fundamental role of libraries in building digital catalogs and developing machine-readable citation systems
