Automatic Summarization for Terminology Recommendation: the case of the NCBO Ontology Recommender

P López-García, S Schulz, R Kern – International SWAT4LS Workshop, 2014

My Places Diary – Automatic Place and Transportation- Mode Detection

A Weber, S Ladstätter, P Luley, V Pammer – Proceedings of the 11th International Conference on Mobile and Ubiquitous Sy…, 2014

Play, that tracks places and movements of users throughout the day. It includes two innovative features: Firstly users’ home and workplaces are detected automatically, based on heuristics derived from earlier work on automatic semantic place detection. Additional place labels are provided via open geo data sources. The position is determined…

Detecting Outliers in Cell Phone Data: Correcting Trajectories to Improve Traffic Modeling

C Horn, S Klampfl, M Cik, T Reiter – Journal of the Transportation Research Board, 2014

Using cell phone signaling data for traffic modeling has great potential. Due to the high coverage rate, it can be used in addition to stationary sensors or even act as replacement when deploying stationary sensors is not possible and/or too expensive. Though, one must be aware that cell phone signaling…

The Impact of Image Descriptions on User Tagging Behavior: A Study of the Nature and Functionality of Crowdsourced Tags

Continuous learning with a quiz for stroke nurses

A Fessl, M Bratic, V Pammer – Int. J. Technology Enhanced Learning, 2014 – Dr. Ambjörn Naeve

A continuous learning solution was sought which allows stroke nurses to keep the vast body of theoretical knowledge fresh, stay up-to-date with new knowledge, and relate theoretical knowledge to practical experience. Based on the theoretical background of learning in the medical domain, reflective and game-based learning, we carried out a…

Future Directions for Visualisation

Using Semantics for Interactive Visual Analysis of Linked Open Data

G Tschinkel, E Veas, B Mutlu, V Sabol – CEUR Workshop Proceedings ( Vol-1272, 2014

Providing easy to use methods for visual analysis of Linked Data is often hindered by the complexity of semantic technologies. On the other hand, semantic information inherent to Linked Data provides opportunities to support the user in interactively analysing the data. This paper provides a demonstration of an interactive, Web-based…

Exploring real world points of interest: Design and evaluation of object-centric exploration techniques for augmented re…

M Tatzgern, R Grasset, E Veas, D Kalkofen, H Seichter, D Schmalstieg – Pervasive and Mobile Computing, 2014

Augmented reality (AR) enables users to retrieve additional information about real world objects and locations. Exploring such location-based information in AR requires physical movement to different viewpoints, which may be tiring and even infeasible when viewpoints are out of reach. In this paper, we present object-centric exploration techniques for handheld…

Scaling the support for informal learning at the workplace: a model and four designs from a large-scale design-based res…

T Ley, J Cook, S Dennerlein, M Kravcik, C Kunzmann, K Pata, J Purma, J Sandars, P Santos, A Schmidt, M AL-Smadi, C Trattner – British Journal of Educational Tech…, 2014

Workplace learning happens in the process and context of work, is multi-episodic, often informal, problem based and takes place on a just-in-time basis. While this is a very effective means of delivery, it also does not scale very well beyond the immediate context. We review three types of technologies that…

Making Sense of Bits and Pieces: A Sensemaking Tool for Informal Workplace Learning

S Dennerlein, M Rella, V Tomberg, D Theiler, T Treasure-Jones, M Kerr, T Ley, C Trattner – in press, 2014

Sensemaking at the workplace and in educational contexts has been extensively studied for decades. Interestingly, making sense out of the own wealth of learning experiences at the workplace has been widely ignored. To tackle this issue, we have implemented a novel sensemaking interface for healthcare professionals to support learning at…

Security Concepts for a Distributed Architecture for Activity Logging and Analysis

V Pammer, H Stern, S Edler, D Hein, M Pirker, R Bloem, A Wertner – 14th International Conference on Knowledge Technologi…, 2014

We describe security concepts for a distributed architecture for activity logging and analysis. The described system collects user and usage data from multiple devices (PC and mobile). Such data is used to create open learner models for reflection on and improvement of time management. Additionally, such data is the basis…

Application overlapping user profiles to foster reflective learning at work

A Fessl, G Wesiak, G Luzhnica – Proceedings of the 4th Workshop on Awar…, 2014 – M. Kravcik, A. Mikroyannidis, V. Pammer, …

Reflective learning is an important activity of knowledge workers in order to improve future working-behaviours. The insights gained by reflective learning are based on re-experiencing and re-evaluating past working situations. One time- and cost-eff ective way to support reflective learning is the employment of applications that collect data about working processes,…

Proceedings of the 4th Workshop on Awareness and Reflection in Technology-Enhanced Learning In conjunction with the 9th…

M Kravcik, A Mikroyannidis, V Pammer, M Prilla, T Ullmann, F Wild – CEUR Workshop Proceedings, 2014

Awareness and reflection in technology enhanced learning (Editorial)
