Most sites are viewable by the public, not just the people you are intending to communicate with. Even non-public sites may be sharing some information with, for example, their advertisers. Never assume that information you provide on a Web page is private.

Beyond Jeopardy! Adapting Watson to New Domains Using Distributional Semantics

Thursday, November 29, 2012

Last year, a question-answering system built at IBM, named Watson, won the game show Jeopardy! The system combines a large database of knowledge with natural language processing abilities. IBM researchers are now investigating how to use Watson in specialized domains, including health care. On November 9, Alfio Gliozzo, a member of the research staff at the IBM T.J. Watson Research Center, gave a talk at ICSI about the future of Watson. We have now made the slides available.

Many people assume that their online communication is private. While one-to-one communication online may be intended as private, if it is not encrypted, it is not private. Whenever information is sent online, there is the possibility that someone other than the intended recipient can view it. Encryption helps prevent the information from being seen by a third party, so sensitive information (such as emails, chat, or video calls containing information that you want to keep between you and the recipient) should always be encrypted.

Profile: Nelson Morgan - Part 2

Wednesday, November 7, 2012
This is part two of a profile on Nelson Morgan. You can read part one here.

In 1988, ICSI ramped up to full staff, and Morgan began in his role as leader of the Realization Group. The group would focus both on building massively systems and on applications in speech recognition.

The group’s early successes were in designing and building machines powerful enough to do speech recognition.  In 1989, the group designed an array of digital signal processing chips in a ring topology that used programmable gate arrays to interconnect processors.
