LFG systems and LFG computer implementations

[何萬順One-Soon Her]

Dear Stefan,

Probably the most successful commercial MT system based on LFG, and yet
least known in the LFG circle, is the Apptek system (www.apptek.com), which
covers multiple language pairs.

The system was first developed in the late 80's by the Provo-based firm
Executive Communication Systems (ECS), with Dan Higginbotham as the chief
architect, Joseph Pentheroudakis the English linguist, and me the Chinese
linguist.

The McLean-based firm Apptek developed the English-Arabic system with the
ECS LFG-based parser in the early 90's and later acquired the entire ECS
system and has since been a highly successful company of language
technologies.

The gist of the early ECS system was described in two early papers:
One-Soon Her, Dan Higinbotham, and Joseph Pentheroudakis, 1991. An LFG-based
machine translation system. *Computer Processing of Chinese and Oriental
Languages* 5.3/4, 285-97 (INSPEC)

One-Soon Her, Dan Higinbotham, and Joseph Pentheroudakis, 1994. Lexical and
idiomatic transfer in machine translation: an LFG approach. In Don Ross and
Dan Brink (eds.) *Research in Humanities Computing 3*, 200-16, Oxford:
Oxford University Press

> Block und Hunze: 1986,
> Eisele und Dorre: 1986,
> Wada und Asher: 1986,
> Butt, King, Niño und Segond: 1999, Butt, Dyvik, King, Masuichi und
> Rohrer: 2002

> I am probably missing relevant pointers ...

> • Deutsch (Rohrer: 1996, Berman: 1996, Kuhn und Rohrer: 1997, Forst:
> 2006, Forst und Rohrer: 2009)
> • Englisch (King und Maxwell III: 2007)
> • Französisch (Frank: 1996)
> • Georgisch (Meurer: 2009)
> • Indonesisch (Arka, Andrews, Dalrymple, Mistica und Simpson: 2009)
> • Japanisch (Umemoto: 2006)
> • Malagasy
> • Mandarin Chinesisch (Fang und King: 2007)
> • Norwegisch (Ørsnes und Wedekind: 2003, 2004)
> • Spanisch
> • Tigrinya
> • Türkisch (Çetinoglu und Oflazer: 2006)
> • Ungarisch
> • Urdu/Hindi (Butt, King und Roth: 2007, Bögel, Butt und Sulger: 2008)
> • Vietnamesisch
> • Walisisch

> Again the list is probably incomplete and the references inappropriate.

> If there are high profile publications that are based on implementations

> this (for instance Dalrymple/Kaplan's coordination analysis, implemented?).
