Statistics of the wall clock time for 40 test cases by best first search and genetic algorithm. Recall statistics for 256 cases of user evaluation. Precision statistics for 256 cases of user evaluation. The control panel for initiating a Java-based genetic algorithm spider. The display window shows the result of the search process dynamically.
Animation is displayed at the upper right-hand corner.
Control panel which allows user to change parameters during the process is located at the upper portion. Search results are summarized at the center of the window. In this experiment, we developed two Web personal spiders based on best first search and genetic algorithm techniques, respectively. These personal spiders can dynamically take a user's selected starting homepages and search for the most closely related homepages in the Web, based on the links and keyword indexing. A graphical, dynamic Java-based interface was developed and is available for Web access.
