About PWA

The PLUG Word Aligner (PWA) is a collection of tools for the automatic
alignment of word correspondences in bilingual parallel texts. The system
integrates a set of modules for knowledge-lite approaches to word
alignment, with various possibilities to change configuration and to adapt
the system to other language pairs and text types. The system requires
sentence aligned bitexts as its input and produces a list of word and
phrase correspondences in the text (link instances) and an additional
bilingual lexicon from these instances (type links).

PWA comprises 2 word alignment systems, the Linköping Word Aligner (LWA)
and the Uppsala Word Aligner (UWA). Both system were developed within the
the co-operative project on parallel text, PLUG, that was carried out
between November, 1997 and March, 2000. The system was developed at the
Department of Computer and Information Science at Linköping University,
Linköping/Sweden and the Department of Linguistics at Uppsala University,
Uppsala/Sweden. PWA integrates both systems in the modular corpus toolbox
Uplug and includes additional tools for the automatic generation of
monolingual word collocations  (phrases) and for the automated evaluation
of alignment results (the PLUG Scorer - PLS).
