Checkbox

• [x] Confirm that this PR is linked to the dataset issue.
• [x] Create the dataloader script seacrowd/sea_datasets/{my_dataset}/{my_dataset}.py (please use only lowercase and underscore for dataset folder naming, as mentioned in dataset issue) and its __init__.py within {my_dataset} folder.
• [x] Provide values for the _CITATION, _DATASETNAME, _DESCRIPTION, _HOMEPAGE, _LICENSE, _LOCAL, _URLs, _SUPPORTED_TASKS, _SOURCE_VERSION, and _SEACROWD_VERSION variables.
• [x] Implement _info(), _split_generators() and _generate_examples() in dataloader script.
• [x] Make sure that the BUILDER_CONFIGS class attribute is a list with at least one SEACrowdConfig for the source schema and one for a seacrowd schema.
• [x] Confirm dataloader script works with datasets.load_dataset function.
• [x] Confirm that your dataloader script passes the test suite run with python -m tests.test_seacrowd seacrowd/sea_datasets/<my_dataset>/<my_dataset>.py or python -m tests.test_seacrowd seacrowd/sea_datasets/<my_dataset>/<my_dataset>.py --subset_id {subset_name_without_source_or_seacrowd_suffix}.
• [ ] If my dataset is local, I have provided an output of the unit-tests in the PR (please copy paste). This is OPTIONAL for public datasets, as we can test these without access to the data files.

1. Did you happen to not implementing the meta field for SEACrowd QA? Prob you might want to pull the latest QA schema first to fix it
2. I saw in complex subset data, it has tipe key (prob type key in Indonesian), which has 4 distinct values for train (image 1) and 5 for test (image 2)

Would you like to add it to the meta field as well for SEACrowd and introduce it as a new feature for the complex source schema?

A quick comment: I saw some inconsistencies when addressing single/simple subset names. Would you mind amending this first, @muhammadravi251001? Thanks!

This is done by changing the single subset name to simple. From the paper & dataset itself, the author uses single and simple interchangeably -> single for the dataset name and simple for the explanation on the paper. Done on https://github.com/SEACrowd/seacrowd-datahub/pull/641/commits/ef563f67f22fd667e440cfc785b4f1cb230ef94a commit.

I've already added the meta field on the https://github.com/SEACrowd/seacrowd-datahub/pull/641/commits/735cd2e5b77a51f29fe46cc5dd2740478bc0e99f commit.

Alright, done in https://github.com/SEACrowd/seacrowd-datahub/pull/641/commits/f2aec29b6fe595cab840751c3db8ecbe5e8bfe8c commit.
