Text visualization: seeing beyond information retrieval

摘要

Extracting information (as opposed to retrieving documents) from collections of raw, unstructured text is now a viable technology. Applications of this technology include automatic population of databases (allowing data-mining, OLAP, and DSS applications to be applied to unstructured text) and sophisticated filtering. Such systems have been hand-crafted heretofore, but pioneering products such as TASC's TextOre is making this technology a practical commodity.
