Working Group(s)

The Advanced Community Information Systems (ACIS) group supports professional communities with heterogeneous needs by open and responsive community environments. Results of our research are advancing the emerging Web Science discipline by new analysis and engineering methodologies for large-scale and heterogeneous information systems.

Overview

Social Software and Community Information Systems are a combination of work practices, information, people, and digital media theories organized in a way that they support the goals of the community. Metadata in community information systems stabilize the ongoing change management process in these systems. The research goal of the ACIS work group is a better understanding of the creation, use, and maintenance of metadata in the context of social software and community systems. Metadata are based on international standards in different domains like audio-visual media retrieval and processing, technology enhanced learning, cultural heritage, and geographical information systems.

Central for our approach is our reflective conceptual architecture ATLAS which incorporates a set of (self-)monitoring tools for the community members and the repository/community middleware. Communities can assess their community needs and evolve the community through the development and change of the community information systems. The monitoring tools allow the measurement, analysis and simulation of community aspects with methods from the semantic web, information retrieval & visualization, data/text/media mining, geospatial database querying, social network analysis, transcriptive algorithms etc. An overview about our activities is given in Algorithms on Complex Dynamic Networks. The tools are bundled in a MediaBase. MediaBases are available online for certain communities like PROLEARN Academy, and Bamiyan Valley Development. Within the research cluster UMIC of the German Excellence Initiative, we have developed this scenario. Virtual Campfire is an advanced scenario framework to create, search, and share multimedia artifacts with context awareness cross communities. Hosted on the basic component the Community Engine, Virtual Campfire provides communities a set of Context-Aware Services and Multimedia Processor Components  to connect to heterogeneous data sources. Through standard protocols a large variety of (mobile) interfaces facilitate a rapid design and prototyping of context-aware multimedia community information systems. The successful realization of a couple of (mobile) applications listed as follows has proved the concept and demonstrated Virtual Campfire in practices. 

On the database/repository level we use and develop further scalable state-of-art database technologies for the management of mass data and metadata for community systems. On the middleware level we realize scalable community hosting services like single-login, variable and fine-granular access control, mobility support, multimedia management, multimedia annotation, interoperable search and retrieval, matching, data/text/media mining etc. Recently, we have started to adapt the XMPP for real-time mobile collaboration services.

Current projects

  • Bamiyan Valley Development Community

    The joint Community of Bamiyan Development aims at bringing together experts from diverse disciplines in the area of preservation of the Bamiyan site in Afghanistan. We attempt to bridge the gaps between different generations, disciplines and cultures on a global scale.

  • GaLA

    Games and Learning Alliance - The European Network of Excellence on Serious Games - EU FP7 IST ICT NoE Project

  • LAYERS

    Learning Layers - Scaling up Technologies for Informal Learning in SME Clusters - EU FP7 ICT Integrated Project

  • METIS

    Meeting Teachers' Co-Design Needs by Means of Integrated Learning Environments - EU LLP KA3 Multilateral Project

  • Mobile Multimedia Cloud Computing

    Cloud computing envisions the notion of delivering software services and customizable hardware configurations to public access, similar how public utilities (electricity, water, etc.) are available to the common man. The cloud abstracts infrastructure complexities of servers, applications, data, and heterogeneous platforms, enabling users to plug-in at anytime from anywhere and utilizes storage and computing services as needed at the moment. The goal of our mobile multimedia cloud (i5Cloud) is to provide infrastructure as a service (IaaS) and platform as a service (PaaS) for diverse services and applications in the domain of (mobile) multimedia and large-scale social network analysis.

  • Multimedia Metadata Community

    The MPEG-7 & MPEG-21 community aims at bringing together experts from research and industry in the area of multimedia meta data interoperability for collaborative working environments.

  • PROLEARN Academy

    The PROLEARN Academy transfers research results into education and training programmes, international conferences, and scientific journals designed to federate and showcase European leadership in the field of Technology Enhanced Learning.

  • ROLE

    Responsive Open Learning Environments - EU FP7 ICT IP Project

  • SunSITE Central Europe

    The SunSITE project at RWTH Aachen University started 1995 as a hosting system for open software and content. Today the SunSITE contains also information about science, culture and virtual communities. And we still run www and ftp servers giving access to the SunSITE Software Archive.

  • The XMPP Experience

    The Extensible Messaging and Presence Protocol (XMPP) is an open and extensible protocol for the exchange of XML data in near real-time. Although most use cases of the protocol are still coined by the protocol's instant messaging background, it is also interesting for a more general range of services, particularly lightweight mobile middleware. The goal of the project is to systematically design, implement, and evaluate XMPP related services in a community information system and to share knowledge among the members of the project.
