Unstructured information represents the largest, most current, and fastest growing source of information that is available today. This information exists in many different sources such as call center records, repair reports, product reviews, e-mails, and many others. The text analysis features of IBM InfoSphere Warehouse can help you uncover the hidden value in this unstructured data. This series of articles covers the general architecture and business opportunities of analyzing unstructured data with the text analysis capabilities of InfoSphere Warehouse. The integration of this capability with IBM Cognos reporting enables people across the company to exploit the text analysis results.

The first article of this series gave an overview of the text analysis capabilities in InfoSphere Warehouse and showed how to use regular expressions to extract concepts from free-form text. This second article shows you how to use dictionaries for concept extraction and how you can use taxonomies to structure them. It also explains how you can present the results in an interactive Cognos report.
