2.1 A lexical analyser for Portuguese: PALMORF
PALMORF is a so-called morphological or lexical analyser, a computer program that
takes running text as input and yields an analysed file as output where word and
sentence boundaries have been established, and where each word form or "wordlike"
polylexical unit is tagged for word class (PoS), inflexion and
derivation/composition, with morphologically ambiguous words receiving multiple
tag lines. The notational conventions used by PALMORF match the input
conventions for a CG disambiguation grammar. With a CG-term, an ambiguous list
of morphological readings, as in (1), is called a cohort.

In example (1), the word form 'revista' has been assigned one noun-reading (female
singular) and four verb-readings, the latter covering three different base forms,
subjunctive, imperative, indicative present tense and participle readings. By
convention, PoS and morphological features are regarded as primary tags and coded
by capital letters. In addition there can be secondary lexical information about
valency and semantic class, marked by bracketing, like for intransitive verbs
(“rever” - ‘leak through’) , for monotransitive verbs (“rever” - ‘see again’),
for pre-name distribution (“revista VEJA” - ‘VEJA magazine”), for
'readable object' or for +CONTROL and +PERFECTIVE ASCPECT
(“revista” - ‘review’).
