Drill Clouds for Search Refinement
I'd like to introduce something I call drill clouds , an extension to tag clouds for search refinement in information retrieval. I will be using an experimental Lucene -based search platform that I have developed, called Ungava (more in this later), which includes my implementation of drill clouds. Note that much of this posting is derived from a posting of mine on drill clouds on the CISTI Lab wiki . Drill clouds are what I call an extension to tag clouds to make them a useful tool for search refinement. That is, to use a tag cloud to refine an existing query by adding new elements to the query through interactions with the cloud. As this results in a kind of drill-down search behaviour, these new clouds have been named drill clouds . Some differences between traditional tag clouds and drill clouds: Tags in drill clouds can be any useful metadata and are not necessarily user applied or exclusively keyword-like (but can include controlled and uncontrolled vocabularies,...
