on specially made bilingual dictionaries, such as the Collins English-German
(CEG), which have been rewritten in an indexed form which is easily readable by
computers. This method uses a structured lexical data base (LDB) in order to
correctly identify word categories from the source language, thus constructing
a coherent sentence in the target language, based on rudimentary morphological
analysis. This system uses "frames"<ref name=":0" /> to identify the position a certain word
should have, from a syntactical point of view, in a sentence. This "frames"<ref name=":0" /> are
mapped via language conventions, such as UDICT in the case of English.

In its early (prototype) form LMT<ref name=":0" /> uses three lexicons,
accessed simultaneously: source, transfer and target, although it is possible
to encapsulate this whole information in a single lexicon. The program uses a
lexical configuration consisting of two main elements. The first element is a
hand-coded lexicon addendum which contains possible incorrect translations. The
second element consist of various bilingual and monolingual dictionaries
regarding the two languages which are the source and target languages.
