Identification of Compentences in Self-regulated Learning ProcessesRalf Klamma
The document discusses identifying competencies in self-regulated learning processes. It describes analyzing forums for English language learners to identify goals, expressions, and competencies demonstrated by users. Patterns were found between competencies, learning phases, and social interactions among forum "cliques". The document concludes by proposing a widget-based competence dashboard to provide visibility into a learner's competencies.
Mobile Access to MPEG-7 Based Multimedia ServicesRalf Klamma
This document summarizes a presentation given at the International Conference on Mobile Data Management in 2009. The presentation discussed research into improving mobile access to multimedia services based on MPEG-7 metadata. It described a German research cluster called UMIC that is developing mobile multimedia applications and services. It then discussed methods for enhancing mobile multimedia performance, including distributing services using mobile web services and enterprise service buses. The presentation evaluated these approaches through a system called MobSOS and concluded that scalability and interoperability are important for mobile multimedia services across different platforms.

This document analyzes the co-authorship network of authors who have published in the VLDB conference over time. It finds that like other academic networks, the VLDB network exhibits the properties of densification over time, increasing clustering, and the presence of highly connected hubs. Key metrics like diameter and average path length remain small even as the network grows significantly in size.

The Legacy of ROLE - Where are we at the workplace?Ralf Klamma
This slide deck discusses the Responsive Open Learning Environments (ROLE) project. It provides an overview of the ROLE conceptualization of self-regulated learning and technical infrastructure. It then summarizes two case studies that implemented ROLE - the BOOST project which used ROLE to support skills training in businesses, and the VIRTUS project which developed a virtual vocational education system using ROLE. It concludes by discussing the future potential for ROLE in areas like mixed reality environments and domain-specific learning.

DevOpsUse for Large-Scale Social Requirements Engineering @ SIG WELL - EC-TEL...Ralf Klamma
This document discusses using DevOps and social requirements engineering for large-scale projects. It introduces the Requirements Bazaar platform for enabling communication between users and developers on requirements. Users can create components, comment, vote and post requirements. DevOps promotes collaboration between stakeholders, automation, and alignment of objectives. The WEKIT project aims to improve maintenance of aircraft using improved documentation and collaboration between maintenance personnel.
Learning Analytics: Trends and Issues of the Empirical Research of the Years ...Ralf Klamma
This document summarizes the findings of a study analyzing empirical learning analytics research from 2011-2014. The study found that most research examined log data from university students to visualize learning trajectories and predict success or failure. However, some innovative studies looked at informal learning communities, video/audio data, automated assessment, and error diagnosis. The document recommends that future learning analytics research incorporate more educational and psychological theories for a deeper understanding of the issues.
A Short Swim through the Personal Learning PoolRalf Klamma
This document discusses different models of learning and tools to support learning. It summarizes several learning cycles including self-regulated learning cycles and organizational learning cycles. It then describes several digital tools developed by the author to support learning, including tools for video annotation, digital storytelling, and interactive 3D anatomy models. Finally, it compares different delivery models for informal learning solutions and discusses trends toward more client-side web architectures.

Navigation Support in Evolving Communities by a Web-based DashboardRalf Klamma
This document discusses the development of a navigation dashboard to support the evolution of open source software communities. It describes related work on social network analysis and text mining of communities. A survey of open source developers found interest in visualizing the overall community and changes over time through metrics and network graphs. A prototype dashboard was created integrating data from code repositories and mailing lists of three bioinformatics projects. Feedback from community members praised the social network graph and saw potential uses for recruitment, funding, and comparing projects. The conclusions identify interest in reflecting community evolution and network visualizations, with an outlook on expanding text analysis and social features to better support open source communities.
The document discusses big data and learning analytics. It notes the changing roles of researchers from isolated scientists to members of networked communities. It raises ethical concerns about privacy with the collection and analysis of large datasets. The document also discusses lessons learned about ensuring transparency, accountability, and community involvement in the use of data and analytics.
