BasahaCorpus: An Expanded Linguistic Resource for Readability Assessment in Central Philippine Languages

This repository hosts the code and data used for the EMNLP 2023 Main paper entitled "BasahaCorpus: An Expanded Linguistic Resource for Readability Assessment in Central Philippine Languages" by Joseph Imperial and Ekaterina Kochmar.

Dependencies

1. Numpy and Pandas for data processing.
2. Rank-Biased Overlap (https://github.com/changyaochen/rbo).
3. Implementation of cross-lingual n-gram overlap by Imperial and Kochmar (2023, ACL). Code is added to the repository.

Data

The data from these languages are all distributed across the Philippine elementary system's first three grade levels (L1, L2, L3). We sourced this dataset from Let's Read Asia (LRA) with explicit permission obtained to share and conduct research with the corpus.

All used datasets are inside the data folder categorized by language. The formatted .txt and .csv files as the extracted features from the code are included in each language.

Linguistic Feature Extraction

Inside the code folder there are three parser files (syll_parse.py, trad_parser.py, CLGSNGO_parser.py) and three function files (SYLL.py, TRAD.py, CLGSNGO.py). The function files contain the functions for extracting the linguistic features and the parser files are where you input your .csv files to iterate row-by-row. Each parser file will output a .csv file containing the extracted features, which you can combine or concatenate together for experimentation (see examples such as rin_features.csv in the data/features/ folder).
