Advances in authoring tools and improved access to distributed content sources using technologies like Web Services, provide a sea of valuable learning content to learners. However, without better navigation tools, learners will simply drown in this ever-changing sea of information. Tag clouds offer a powerful new approach for navigating eLearning content, especially rapidly evolving content. Rather than having to search for content, Tag clouds allow learners to see popular content and subscribe to content of interest using simple tags. Tag clouds also help content producers classify content using the collective intelligence of their organization. Moreover, the Tag-based classification system improves as more content is published and tagged.
