The electronic lexicon that PALMORF uses, is based on a paper version passive<br />

bilingual Portuguese-Danish dictionary (<strong>Bick</strong>, 1993, 1995, 1997) I have compiled in<br />

connection with my Masters thesis on lexicography (<strong>Bick</strong>, 1993), which is where<br />

information can be found about the lexicographic principles applied. The lexicon file<br />

now covers over 45.000 lexemes, 10.000 polylexicals and about 20.000 irregular<br />

inflexion forms. The present lexical content reflects the constant, circular<br />

interactivity of lexicon, parser and corpus. Over four years, every parse has - also -<br />

been a lexicon check.<br />

Much of the information contained in the original dictionary had to be<br />

regularised and adapted for parsing purposes. Thus, many words had to have their<br />

valency spectrum widened for empirical reasons, and throughout the whole lexicon,<br />

a formal semantic classification was introduced, something a human reader of the<br />

paper dictionary would implicitly derive from the list of translation alternatives.<br />

Also, for use with regular inflexion rules, grammatical combinatorial subcategories<br />

(field 4 in table 2) had to be introduced for verbal (and some nominal) stems.<br />

In (1), a number of authentic lexicon entries is listed, and table (2) summarises<br />

the kind of information that can be found in the different fields of a lexicon entry.<br />
