Abstract: Digital media are used to facilitate social structures thus building digital social networks. Disturbances in such networks occur on different levels (egocentric level, subgroup level, network) and have to be analyzed in the multidimensional context of reference disciplines like sociology and knowledge management. This paper presents a first repository of disturbance patterns for the analysis of digital social networks. Based on the Actor-Network Theory and the Social Network Analysis, new socio-theoretical models for ...

Learning Analytics has become a major research area recently. In particular learning institutions seek ways to collect, manage, analyze and exploit data from learners and instructors for the facilitation of formal learning processes. However, in the world of informal learning at the workplace, knowledge gained from formal learning analytics is only applicable on a commodity level. Since professional communities need learning support beyond this level, we need a deep understanding of interactions between learners and other entities in community-regulated learning processes-a conceptual extension of self-regulated learning processes. In this paper, we discuss scaling challenges for community learning analytics, give both conceptual and technical solutions, and report experiences from ongoing research in this area.

Abstract: The success of multimedia enabled community engines depends on a careful design of the digital media and the related communication/collaboration tools. However, the semantics of the multimedia contents in community communication and collaboration is hard to capture and complex to compute. With the opportunities given by the combination of metadata descriptions standards like MPEG-7 and server-side content-based computations, the manageability of multimedia semantics in community engines becomes more feasible. ...

Barrier free learning on the web is one of the greatest challenges for computer science in the future. While the growth of the internet was exponential in the last years, still many communities don't benefit from web technology for their learning issues due to improper tools and constricted communication processes. These problems increase when developing applications for communities of people with special needs. In this paper we present the case study of a cooperative web-learning environment called SOCRATES to overcome ...

Knowledge and management do not fit prima facie. Management aims at goal-oriented action while in many sciences, especially in the humanities, knowledge and the creation of knowledge have a discursive nature. This process of knowledge creation, interpreting and discussing selected observed or postulated phenomena, is leading to some progress but hard to control. It is important to recognize that the process needs a tight interplay between communicative acts and the organization of knowledge. Furthermore, this can only ...

Multi-perspective problem solutions, leading to an increasing complexity in creating authentic learning scenarios and collaborative learning strategies, have gained the focus of scientific research. In order to assist learners in virtual communities working with digital media artifacts we analyze the needs of communities in different scientific domains ranging from the humanities to engineering. We combine our results with a media theory developed in Germany's first interdisciplinary and collaborative research center on” Media and ...

Integration of heterogeneous data is one of the greatest challenges for versatile e-learning environments, since support for different multimedia data formats is often restricted or adaptions are necessary to fit strict requirements. Therefore, we examine the opportunities given by new metadata standards like MPEG-7 and XML for knowledge management in terms of automated processing, evaluation and presentation of e-content. In Germany's first interdisciplinary and collaborative research center on “Media and Cultural ...

The barrier free internet is one of the greatest challenges for computer science in the future. While in the last years the growth of the internet was exponential, still many potential user communities can not use internet technology for their communication needs because of inappropriate tools and narrowly designed communication processes. These problems become obvious when transferring applications to communities of people with special needs. Many people suffering from aphasia are not able to interact with current chat tools ...

Abstract: Knowledge creation processes in the cultural sciences have a discursive nature. The cultural scientists participating in these discourses build a community of practice. Reifications in information systems should support four concepts:(1) Content description by metadata,(2) coverage within standards,(3) repository technologies, and (4) platform independence of applications. By the combination of these concepts information systems support cultural scientists to extract and manage knowledge about high-level semantics of ...

This study compares Face-to-Face dialogues with Computer-Mediated-Communication and noninteractive oral and written tasks in German-speaking aphasic and non-aphasic persons. The research project follows an interactive and media-specific hypothesis, which refers to the concept of adaptation. It is claimed that variation in agrammatic symptoms does not directly mirror the basic syntactic disorder, but reveals adaptation to various interactive and media-specific demands. Therefore, we compared in an experimental study the impact of ...

Knowledge-based hypermedia systems are used in scholarly communication since more than 2000 years, eg the Babylonian Talmud. Many different computer-based hypermedia systems have been successfully created for the humanities, too. But, cross-university or even university-wide use of these systems for e-learning purposes in the humanities is seldom if ever. In this paper, we argue, that only a deep analysis of hypermedia usage in scholarly communication and teaching can disclose non-trivial ...

Abstract: Tagging is an extremely popular mechanism in many Web 2.0 applications to create metadata supporting search and retrieval of arbitrary multimedia information like digital images, video or audio. However, compared to the syndicated multimedia information itself, the metadata are still “sticky”. They cannot be accessed across several Web 2.0 applications, their semantic enrichment is not possible and they cannot be embedded in the local practices of communities of practice. Here, we present a multimedia tagging ...

Due to recent developments in the domain of mobile broadband communication and a growing availability of standardized development tools for mobile devices a new generation of mobile services and applications is expected to emerge in the near future combining well-established multimedia and community concepts with mobile aspects. However, it is often challenging to predict the success of such new services. In this paper we present a short overview of the MobSOS testbed and its homonymous success model ...

Abstract: Digital non-linear story-telling is an ideal approach to share entrepreneurial knowledge in large distributed communities and networks. Story-telling combines semantic knowledge and episodic knowledge by explicit problem solving strategies. In order to facilitate entrepreneurial knowledge sharing authoring environments based on multimedia repositories as well as advanced story players are needed. Interoperability with existing information systems can be enhanced by relying on multimedia description standards like ...

Abstract: With the advent of Web 2.0 technologies a new attitude towards processing contents in the Internet has emerged. Nowadays it is a lot easier to create, share and retrieve multimedia contents on the Web. However, with the increasing amount in contents retrieval becomes more challenging and often leads to inadequate search results. One main reason is that image clustering and retrieval approaches usually stick either solely to the images' low-level features or their user-generated tags (high-level features). However, this ...
