5. CONCLUSIONS AND FUTURE WORK
In this paper, we investigated the influence of different tagging styles, namely describers and categorizers on
enlarging the metadata descriptions of digital educational resources. The results of our study performed with
the dataset of an existing LOR, namely OpenScienceResources Repository showed that describers produce
tags that are significantly different from formal metadata, whereas categorizers mainly follow the formal
metadata generated by metadata experts or content providers. As a result, considering tagging motivation
during folksonomies analysis could facilitate capturing enlarged metadata descriptions of digital educational
resources. Future work includes deeper analysis to the results of our study, so as to identify the effect of
describers’ and categorizers’ social tags to the enlargement of metadata descriptions for digital educational
resources with different granularity levels and different formats.
