Though almost all words can be analysed, more than half the word form tokens
get more than one reading, the average being 2.0 - 2.1 75 .
The cumulative percentage column shows the proportion of word forms having n
or fewer readings. The graphical representation in (2) maps inverse cumulation,
showing the proportion of word form tokens with n or more readings.
(2) Morphological ambiguity in Portuguese
(in an excerpt from the Borba-Ramsey Corpus)
75 These are the figures without the use of portmanteau tags. Later, portmanteau tags were introduced for 3 cases of verbal
inflexion: the 0/1/3S tag for infinitives, the 1/3S tag for some present subjunctive cases, and the PS/MQP tense tag for some
cases of 1.person and 3.person plural endings. The figure for the new version is, accordingly, lower: 1.7 readings per word
form.
The missing portmanteau-tags and the ensuing close lumping of certain tags is also the reason for the strange
relative ambiguity peak at the 4-readings mark.
