Finding what you need on the Web can be like searching a roomful of file cabinets labeled "A-Z." Web search engines often provide an excessive number of sites to screen, and provide no guide to data quality.
Autonomy Corp Plc, the UK knowledge management software developer, has released ActiveKnowledge, its online research tool (CI No 3,622) and said it expects most web search engines to eventually run on similar technology.
Pattern-matching techniques based on neural networking are leagues above web search engines. But their complexity, and performance-sapping hardware appetite keep them restricted to those with very deep pockets.
