Research and development departments of major companies, including IBM and Microsoft, are researching text mining techniques and developing programs to further automate the mining and analysis processes. Text mining software is also being researched by different companies working in the area of search and indexing in general as a way to improve their results.

There are a large number of companies that provide commercial computer programs:

• AeroText - provides a suite of text mining applications for content analysis. Content used can be in multiple languages.
• AlchemyAPI - SaaS-based text mining platform that supports 6+ languages. Includes named entity extraction, keyword extraction, document categorization, etc.
• Autonomy - suite of text mining, clustering and categorization solutions for a variety of industries.
• Endeca Technologies - provides software to analyze and cluster unstructured text.
• Expert System S.p.A. - suite of semantic technologies and products for developers and knowledge managers.
