MICROSOFT WORD's Grammar Check--A Word to the unwise--program's grammar check isn't so smart

Sandeep Krishnamurthy thinks Microsoft can do a lot better. Karen Ducey/P-I Sandeep Krishnamurthy shows a marked up example of how Microsoft's Word grammar checker doesn't quite do the job. The University of Washington associate professor has embarked on a one-man mission to persuade the Redmond company to improve the grammar-checking function in its popular word-processing program. Krishnamurthy is also trying to raise public awareness of the issue.

"If you're a grad student turning in your term paper, and you think grammar check has completely checked your paper, I have news for you--it really hasn't," he said.
