Dynamic Inverted Quadtree: A Structure for Pictorial Databases.
Peer reviewed Peer reviewed
Vassilakopoulos, Michael; Manolopoulos, Yannis – Information Systems, 1995
Presents an improved inverted region quadtree variation called Dynamic Inverted Quadtree that is able to support and index a pictorial database. Pattern-searching algorithms are described, and the space needs of Fully Inverted and Dynamic Inverted Quadtrees are analytically compared based on a model of image randomness expressed as a branching…

Adaptive Clustering of Hypermedia Documents.
Peer reviewed Peer reviewed
Johnson, Andrew; Fotouhi, Farshad – Information Systems, 1996
Discussion of hypermedia systems focuses on a comparison of two types of adaptive algorithm (genetic algorithm and neural network) in clustering hypermedia documents. These clusters allow the user to index into the nodes to find needed information more quickly, since clustering is "personalized" based on the user's paths rather than…
