Three Dimensional Tagcloud visualization for tourism
Metadata creation along with growth of social bookmarking emerged an approach named tagging. Often people look for location along with its route and detailed information about its surrounding. Mobile users may opt for current event that is taking place in the current location along with historical background of their surroundings and events that happen over time. They are provided with information on spatial context of location which harvests context information from freely available source and tag cloud visualization is created for this data. Firstly, Geo-referenced data which is close to selected point is gathered. Then gathered information is filtered based on the frequency of words from harvested data. Filtered data is then visualized as tag cloud in R shiny.
