libEscansión

A Python library for for metrical scansion of mixed Spanish verses

libEscansión is a state-of-the-art Python library for analysing Spanish mixed verses. It parses the verse to find syllabic nuclei, rhythmic pattern, assonance, and consonance, as well as to provide a phonological transcription of the syyllables. It scores 98.64% accuracy against the manually annotated corpus [ADSO 100] with the option adso=True, which forces considering interjections as non-stressed to meet ADSO's criteria. This tops the until-now state-of-the-art. Nevertheless, vanilla scansion still outperforms the state-of-the art as it achieves 96.8%. Furthermore, after evaluating the corpus' manual scansion and spelling, we found that the disagreement was in most cases due to an improper spelling or even to non-standard human analysis (unstressed interjections, adverbd in -mente lacking secondary stress, etc.). With a corrected corpus, the agreement reaches 99.13 %, being the resting 0.87% non-erroneus disagreements.

This library is part of the research project Sound and Meaning in Spanish Golden Age Literature. It was created as a means to generate a corpus of parsed metres, which is publicicily accessible here

Requeriments

Following libraries are required:

• stanza >= 1.4.2 with Spanish language models
• fonemas >= 2.0.16

Usage example

The library provides the class VerseMetre. It accepts an obligatory string for the verse and an optional list of integers with possibles syllable-counts. If a second argment is not provided, it performs a regular scansion, i.e., with all natural dialoephas.

>>> import libEscansion
>>> verse = verse = libscansion.VerseMetre('Cerrar podrá mis ojos la postrera ', [11,8,7])
>>> verse.count 
11
>>> verse.syllables
['θe', 'rAɾ', 'po', 'dɾA', 'mis', 'O', 'xos', 'la', 'pos', 'tɾE', 'ɾa']
>>> verse.nuclei  
'eAoAiOoaoEa'
>>> verse.rhyme
'eɾa'
>>> verse.asson
'ea'
>>> verse.rhythm  
'-+-+-+---+-'

The directory 'utils' contains a file that can be used to test the library against ADSO 100 (or any other corpus of sonnets whasoever as long as they are encoded as XML-TEI with their metres are annotated). In the same directory containing the XML files, type:

./adso100test.py *xml
