de Paiva is a
mathematician and computer scientis working in California, USA
the Natural Language and AI Research Laboratory of Nuance Communications, Inc.
She was, until September 2010, a search analyst for Cuill, Inc.
in Menlo Park, CA. She also worked for Rearden Commerce, now Deem, Inc.
She was (for almost nine years) a research scientist at the
Intelligent Systems Laboratory
of PARC (Palo Alto Research
She received her PhD in Mathematics from Cambridge University
for work on "Dialectica Categories",
and has ever since worked on logical
approaches to computation, especially using Category Theory.
She's an Honorary Research Fellow at the School
of Computer Science, University
of Birmingham, UK.

- Talk at SRI AI Center, "A Bridge not too far", Thursday January
21, 2010 at 16:00. Abstract:
For many years (from 2000 to May 2008) I worked with PARC's natural
language processing group on technologies for (automatically) creating
logical forms out of natural language sentences. This lofty goal was
somewhat mocked and derided by friends both in logic and in computer
science. Logicians supported by the view that natural language is too
complicated for logic, computer scientists convinced that all virtue
lies with statistics and logic has no part in it. I believe both sets
of friends are wrong and that the project, which is
the Holy Grail of several other groups of researchers, is very much
alive and up for grabs. That judiciously picking of competing
alternatives (in the vast space of possibilities) is a first step and
that Open Source software is the right way of doing it. In this talk I
would like to summarize what I learned, what I think would work best
and I want to try to sketch how one could go about it. Also I would
like to get at least some conclusions of what has been achieved and
what small projects one could easily do to put in place a few more
pieces of the big puzzle. slides.

Last year I left PARC after almost nine years in residence, to join
Cuil, a start up company then in stealth mode. Three months
later, Cuil launched with a lot of buzz and a product that is
innovative to the hilt. This was the beginning of an exciting (and
bumpy) journey over the unchartered territory of Searchland, part of
the larger and (to me) still mysterious continent of StartUpLand.
In this talk I will discuss this journey and highlights so far..

I do like to work with other people. Here is an incomplete (and vaguely
chronological) list of people I am working with/have worked with:
I am a Brazilian, who misses very much Rio de Janeiro. My old `alma
mater' is PUC in Rio.
work `alma mater' is Cambridge, where I spent 11 years.
I am especially
fond of the computer laboratory.
I have a lovely daughter, a
beautiful son and a great husband.
pictures of the kids are here,
A blog is de
riguer, nowadays. Mine is not about work, in case you were wondering.
But I hope to get a work one, soon.
Some work blogs that I'd like to check, once in a while: Andrej, Zach, and Restall.
