An efficient Web information extracting system

In order to enhance the information quantity and quality for IHWA (information harvest warehouse) information provision system, a mobile information extracting system is developed that effectively and efficiently extracts necessary information from various remote web sites. The system spawns and controls mobile agents that move to remote sites, extract necessary information remotely, and send back the extracted information to a host. This way of information extraction can minimize the transmission overhead on networks as well as the processing overhead of the center host. Moreover, the mobile agent can be configured to better adapt to its remote site characteristics.
