Designing Innovative Digital Technologies for Knowledge Management and Data-driven Business: A Case Study

A Fessl, S Feyertag, V Pammer – In Proceeding of 15th International Conference on Knowledge Technologies and Data-driven…, 2015

This paper presents a case study on co-designing digital technologies for knowledge management and data-driven business for an SME. The goal of the case study was to analyse the status quo of technology usage and to develop design suggestions in form of mock-ups tailored to the company's needs. We used…

The Social Semantic Server: A Flexible Framework to Support Informal Learning at the Workplace

S Dennerlein, D Kowald, E Lex, D Theiler, E Lacic, T Ley, V Tomberg, A Ruiz-Calleja – …, 2015 – In Proceeding of 15th International Conference …

Informal learning at the workplace includes a multitude of processes. Respective activities can be categorized into multiple perspectives on informal learning, such as reflection, sensemaking, help seeking and maturing of collective knowledge. Each perspective raises requirements with respect to the technical support, this is why an integrated solution relying on…

Smart Booking Without Looking: Providing Hotel Recommendations in the TripRebel Portal

M Traub, D Kowald, E Lacic, P Schoen, G Supp, E Lex – In Proceeding of 15th International Conference on Knowledge Techno…, 2015

In this paper, we present a scalable hotel recommender system for TripRebel, a new online booking portal. On the basis of the opensource enterprise search platform Apache Solr, we developed a system architecture with Web-based services to interact with indexed data at large scale as well as to provide hotel…

Evaluating Tag Recommender Algorithms in Real-World Folksonomies: A Comparative Study

D Kowald, E Lex – ACM, 2015 – 9th ACM Conference on Recommender Systems

To date, the evaluation of tag recommender algorithms has mostly been conducted in limited ways, including p-core pruned datasets, a small set of compared algorithms and solely based on recommender accuracy. In this study, we use an open-source evaluation framework to compare a rich set of state-of-the-art algorithms in six…

Tackling Cold-Start Users in Recommender Systems with Indoor Positioning Systems

E Lacic, D Kowald, M Traub, G Luzhnica, J Simon, E Lex – ACM, 2015 – 9th ACM Conference on Recommender Systems

In this paper, we present work-in-progress on a recommender system based on Collaborative Filtering that exploits location information gathered by indoor positioning systems. This approach allows us to provide recommendations for "extreme" cold-start users with absolutely no item interaction data available, where methods based on Matrix Factorization would not work.…

ScaR: Towards a Real-Time Recommender Framework Following the Microservices Architecture

E Lacic, D Kowald, M Traub, E Lex – ACM, 2015 – 9th ACM Conference on Recommender Systems

Various recommender frameworks have been proposed, but still there is a lack of work that addresses important aspects like: immediately considering streaming data within the recommendation process; scalability of the recommender system; real-time recommendation based on different context dependent data. To bridge these gaps, we contribute with a novel recommender…

The Value of Self-Tracking and the Added Value of Coaching in the Case of Improving Time Management

V Pammer, M Bratic, S Feyertag, N Faltin – Proceedings of the 10th European Conference on Technoloy Enhanced Learning (E…, 2015

We report two 6-week studies, each with 10 participants, on improving time management. In each study a different interventions was administered, in parallel to otherwise regular work: In the self-tracking setting, participants used only an activity logging tool to track their time use and a reflective practice, namely daily review…
