Expert Systems: Limited but Powerful
Article Abstract:
Expert systems are artificial intelligence systems that combine knowledge, inference procedures, and ways of applying knowledge to solve specialized problems. Production rules are often used to formulate logical lines of reasoning. Two major categories of problem-solving approaches are used by expert systems. Some search for solutions in search space efficiently and others narrow the search to manageable subsets of solutions. Limitations of expert systems include narrow domain of expertise, stylized languages and conclusions, laborious construction, fragile behavior, and need for an engineer to operate the system. Some systems are routinely used in real-world settings, but most are still being refined. A table lists existing expert systems and an insert describes the computer- based diagnostic consultant for internal medicine - Internist-1. Systems discussed include Mycin, Dendral, and R1.

The China link: advice from an expert
Article Abstract:
Learning to understand the Chinese is the greatest business challenge facing American companies wishing to do business in China, according to the author, who spent several years in China as a representative of Honeywell Bull. The Chinese are masters of the art of negotiation, and practice many techniques difficult for Westerners to understand. The US government (which ostensibly supports sale of high-technology products to China) can delay licensing of trade deals by 18 months and more. Americans typically approach business looking for short-term results, but the Asian approach in general, including the Japanese and the Chinese, is to seek long-term relationships. While the climate for doing business in China has improve a lot since 1979, it is still not ideal for every American company.

Laser May Replace Expert Wine Tasters
Article Abstract:
Philip J. Wyatt, president of the Wyatt Technology Co., has used laser analysis to type the quality of wines. The differential light-scattering patterns are correlated to taste-tests of particular wines. Breweries may use the technique to study beer tastes and canning techniques.
