Charting the Future: Scholarly Publishing in CS

We would like to update you on three key policy issues ACM's Publications Board is currently discussing, give you a glimpse of what some of the leaders of the field have told us, and invite your input into the discussion.

The Human Touch

As configuration complexity and scale grow, the need for smarter configuration systems, better online assistance, and the ability to share context with customer service agents will become increasingly important.
DEPARTMENT: Letters to the Editor

Human or Machine?

We wish to clarify an account of the 2014 Turing Test experiment we conducted at the Royal Society London, U.K., as outlined by Moshe Y. Vardi in his Editor's Letter "Would Turing Have Passed the Turing Test?" (Sept. 2014) …
