Ontology Enrichment with Social Tags for eLearning
نویسندگان
چکیده
One of the objectives of this paper is to verify whether it is possible to extract meaningful related tags from a limited set of tagged resources and from resources tagged by only few users. This is the expected situation in a learning community. An additional goal is to assess whether the related tags extracted can be a useful source for enriching an existing domain ontology. A user centered evaluation has been carried out to analyze the effect of the enriched ontology in supporting a learning task in comparison with clusters of related tags. The experiment has been carried out both with beginners and advanced learners.

متن کاملTag Gardening for Folksonomy Enrichment and Maintenance
As social tagging applications continuously gain in popularity, it becomes more and more accepted that models and tools for (re-)organizing tags are needed. Some first approaches are already practically implemented. Recently, activities to edit and organize tags have been described as "tag gardening". We discuss different ways to subsequently revise and reedit tags and thus introduce different ...
