Context of the dissertation & the problem statement
Hypothesis & structure of the study
Cataloguing and metadata
Context of the dissertation
Discovering learning resources
across language boundaries is challenging!
Main problem: the resource & its metadata description are made in a different context from where the resource is discovered and/or actually used
in different languages do not cross-reference via hyperlinks!
Not applicable! Problem statement
Add a rating New kid on the block - tagging Add a tag
New patterns emerge
Social tags make digital trails visible! by Stiphy
The self-organisation aspect of a social tagging system on a learning resource portal helps users discover learning resources more efficiently.
User-generated tags make the system, which operates in a multilingual context, more robust and flexible.
Setting the scene Trilogy of empirical studies What happens when users tag in multiple languages? Are learning resources used across contexts? 2. Metadata ecology more robust and flexibile system 1. Ecology of social search more efficient users 3. Tags connect con-tent across contexts more flexibility Structure of studies
Spanish resource Tag «interactive» Tags create link-structures beween content in different languages Finnish resource Slovakian resource
Austria Hungary Finland Resource that «Travels well» Tags create link-structures beween users in different countries
This opens novel ways for better cross-language discovery of learning resources, paving the way for recommender systems, social navigation and ranking in this domain
I would like to thank everyone involved in this research, especially...
