Automated Information Extraction using Amorphic

The Amorphic system is an adaptive web information extraction scheme for building intelligent systems for mining information from web pages. It can locate data of interest based on domain-knowledge or page structure, can automatically generate a wrapper for an information source, and can detect when the structure of a web-based resource has changed and act on this knowledge to search the updated resource to locate the desired information. This allows Amorphic to adapt to changing structures of websites allowing users to manage their information extraction more effectively. Five different example implementations are described to illustrate the need for information extraction systems capable of extracting information from semi-structured web documents. They demonstrate the versatility of the system, showing how a system, like Amorphic, can be used in systematic data extraction applications that require data collection to be conducted over an extended period of time. The current Amorphic system represents a cost-effective approach to developing large-scale adaptable information extraction systems for a variety of domains.
