Much of my professional work involves software development, most of which is
done in the context of Ultralingua, Inc.
Ultralingua's most visible products are a collection of multi-lingual
dictionary applications for iOS, Android, Mac OS X, Windows, and
a long string of more-or-less obsolete platforms reaching back into the past.
As of 2023, we have several dozen bilingual dictionaries
involving the languages English, French, Spanish, German, Italian, Portuguese, Norwegian,
Latin, Esperanto, Polish, Dutch, Russian, Mandarin, and, of course, Klingon.
We also sell phrasebooks and various other language-related tools.
Our products are driven by the
Ultralingua Application Programming Interface (ULAPI),
which is used in our own consumer products as well as by other software
developers who need linguistic features in their software.
See Assistiveware's Proloquo2Go, a multi-lingual
augmentative and alternative communication (AAC)
tool intended to be used by people with speech disabilities. Proloquo2Go uses ULAPI's
lemmatization and inflection capabilities to help enable children to quickly and naturally
compose complex sentences. In addition to lemmatization (mapping a derived form of a word
to its root word, like "parlions" → "parler") and inflection (verb conjugation, plural formation, etc.),
ULAPI can do number translation (e.g. "123" + "Spanish" → "ciento veintitrés"),
and part-of-speech tagging. At a more abstract level, ULAPI is a morphological analysis
and synthesis engine with many practical applications, and currently available in about a dozen languages.

exploring ways to contribute to the emerging field of
Energy Analytics to help Carleton and others
reduce their energy use and improve their building management. Two recent student projects in

provided a tantalizing view of the potential power of energy analytics, along with some good
infrastructure on which to build.
