Grammatical Annotation of Historical Portuguese: Generating a Corpus-Based Diachronic Dictionary

Part of the Lecture Notes in Computer Science book series (LNAI,volume 9924)


In this paper, we present an automatic system for the morphosyntactic annotation and lexicographical evaluation of historical Portuguese corpora. Using rule-based orthographical normalization, we were able to apply a standard parser (PALAVRAS) to historical data (Colonia corpus) and to achieve accurate annotation for both POS and syntax. By aligning original and standardized word forms, our method allows to create tailor-made standardization dictionaries for historical Portuguese with optional period or author frequencies.

  3. 3.

    TreeTagger does not distinguish between common and proper nouns, but for the ‘unknown’ count, names were removed by inspection.

  4. 4.

    At the time of writing it was not clear if this text had been subject to philological editing in its current form, which might explain its fairly modern orthography.

  5. 5.

    Parts of fused tokens were counted individually in the statistics, the token count is therefore higher than it would be counting the original text tokens as-is.

  6. 6.

    Note that the figures constitute a lower bound. In order to achieve a precision close to 100 %, only chunks with at least 4 (clear Latin 3) non-name words were treated, so individual loan words or mini-quotes are not included.
