For the needs of requirements analysis for workplace-integrated mobile learning designs and the development of a context-sensitive mobile application in those companies we interviewed apprentices from mechanical engineering. Based on a theoretically derived comprehensive catalog of software features, we determined the most used software features by apprentices in the past and those, which are mostly requested by them for the intended application in VET. This includes learning with a diversity of multimedia formats, the support of action-oriented tasks, videos explaining work processes, digital mechanical engineering learning contents, and a cloud system to store and share data. We identified the main tasks of apprentices in mechanical engineering education. These are related to action-oriented work orders, typically composed of analyzing mechanical drawings, planning the work process, milling or turning workpieces and a final quality control. The respective educational characteristics of these learning phases are suitable to be supported by digital media. Though well-used in the private context of the apprentices, in the area of mobile learning in VET and with regard to the educational use of smartphones and tablet computers those devices are currently less utilized in the learning environments of training companies and vocational schools. The results of this survey will be considered for the design of workplace-integrated mobile learning as well as for the development of a mobile application for respective learning scenarios. The focus of the underlying instructional design is on an integrated view of existing work processes, assisting educational materials, and social processes in VET.

In the three-year project Mobile Learning in Smart Factories (MLS), a mobile application for context-sensitive learning will be developed. Apprentices will have the possibility to scan barcodes on machines and receive relevant data directly at their workspace. Trainers have to support the apprentices and need relevant competencies. With regard to the creation and evaluation of workshops for the trainers, we provide insight into the planned project evaluation. The MLS project is funded by the Federal Ministry of Education and Research (Germany, abbr. BMBF).

The changing demands on the vocational education are the starting point of our project. It is funded in the focus area Digital Media in Vocational Training (DIMEBB), in which Web 2.0 technologies and mobile applications are promoted. The Federal Institute for Vocational Education and Training, Germany (n.d.) describes the objective of MLS as “the development of a context-sensitive mobile application for learning and working [...] to initialize sustainable learning”. This includes both of the target groups, apprentices and trainers. Apprentices will be enabled to obtain new competencies in the working process and to reflect their state of learning. Additionally, trainers will be enabled to enhance their media competency and to integrate digital media into the daily work routine. To achieve this, the learning process of the trainers will be supported by additional workshops, which are integrated in the development process of the project and will take place simultaneously with the development of the software and didactically prepared learning scenarios.

The MLS project comprises the development of a software, the creation of learning materials, the realization of related workshops, and an evaluation of the individual components. We present the project plan and its objectives, the application features, the suspected knowledge fields of trainers and researchers, and a major project property, the context sensitivity. The project is in the initial phase. We started with first observations at vocational schools and a company.

The approach utilized by ants has several advantages that are also useful in computer networks: complete distribution, load balancing, finding shortest paths with a high probability. Several routing protocols designed for the area of computer networks have made use of this approach, called ant colony optimization. This paper provides first a broad overview of ant colony optimization-based routing protocols, while focusing on four selected approaches in later sections, describing their operation and discussing their properties in detail.

The Internet brought new ways of communication technologies to live and enhanced people's reachability, augmented possibilities for personal presence and the sharing of information objects. People are engaging in social networks in a steadily growing manner and share information objects within their communities. The high initial amount of data in such networks can serve as foundation of serious investigations towards social interactions of communities of learners. In this paper we introduce the technological foundation and architecture to model, obtain and store such user and object information in so-called Artefact-Actor-Networks. Artefact-Actor-Networks combine classical social networks with artefact networks that are constructed by the use of the information objects and their connections.

In the context of scientific events and topical Research Networks, researchers use Social Media as one main communication channel. This raises the question, how to monitor and analyze such Research Networks. In this chapter we argue that Artefact-Actor-Networks (AANs) serve well for modeling, storing and mining the social interactions around digital learning resources originating from various learning services. In order to deepen the model of AANs and its application to Research Networks, a relevant theoretical background as well as clues for a prototypical reference implementation are provided. This is followed by the analysis of six Research Networks and a detailed inspection of the results. Moreover, selected networks are visualized. Research Networks of the same type show similar descriptive measures while different types are not directly comparable to each other. Further, our analysis shows that narrowness of a Research Network's subject area can be predicted using the connectedness of semantic similarity networks. Finally conclusions are drawn and implications for future research are discussed.

Dazu wird ein Softwaresystem entwickelt, mit dem eine automatische Zitationsanalyse durchgeführt werden kann. Dies umfasst die Untersuchung eines unterliegenden Dokumentennetzwerkes durch die Kombination verschiedener Ansätze der Bibliometrie. Die Ergebnisse der Zitationsanalyse hängen von der Menge und Qualität der unterliegenden Datenbasis ab. Diese wird durch ein Dokumentennetzwerk repräsentiert und besteht im Wesentlichen aus Publikationen und Referenzierungen zwischen diesen. Um diese Datenbasis aufzubauen, werden im Vorfeld Daten verschiedener Formate verarbeitet. Zunächst findet eine Extraktion von Volltexten aus PDF-Dateien statt. Aus den Volltexten werden anschließend Metadaten zu Publikationen und Metadaten zu Referenzen der Literaturverzeichnisse extrahiert. Dieser Extraktionsvorgang verwendet externe Open Source Anwendungen. Da die Datenqualität der Extraktion gering ist, findet eine zusätzliche Nachbearbeitung der extrahierten Daten statt. Die redundant vorliegenden Metadaten werden dabei in ein integriertes Format zusammengeführt. Extrahierte Metadaten zu Publikationen und Referenzen werden anschließend genutzt, um ein Dokumentennetzwerk aufzubauen. Eine passende Lösung zur Datenhaltung wird im Vorfeld durch einen Benchmark ermittelt. Aus dem vorbereiteten Dokumentennetzwerk kann abschließend eine Publikation gewählt werden, für die Literaturempfehlungen ermittelt und präsentiert werden. Da die benötigten Berechnungen zeitintensiv sind und als Grundlage mehrere Hunderttausend Dokumente dienen, werden sie verteilt in einem Rechnercluster durchgeführt. Für die verteilten Berechnungen findet dabei das Hadoop Framework Verwendung.
