  2. Text & Document Visualization • Text not pre-attentive • Text = Abstract Concepts = Very High Dimensionality • Multiple & ambiguous meanings • Combinations of abstract concepts more difficult to visualize • Different combinations imply different meanings • Language only hints at meaning  based on common understanding “How much is that doggy in the window?” • Facilitate Information Retrieval • Collection Overview • Visualize which parts of query satisfied by document / collection • Understand why documents retrieved • Cluster Documents Based on Words in Common • Finds overall similarities among groups of documents • Picks out some themes, ignores others • Map Clusters onto 2D or 3D Representation • Minimize time/effort to decide which documents to examine
