Indojave: RoBERTa-base
This is a pre-trained masked language model for code-mixed Indonesian-Javanese-English tweets data. This model is trained based on RoBERTa model utilizing Hugging Face's Transformers library.
Pre-training Data
The Twitter data is collected from January 2022 until January 2023. The tweets are collected using 8698 random keyword phrases. To make sure the retrieved data are code-mixed, we use keyword phrases that contain code-mixed Indonesian, Javanese, or English words. The following are few examples of the keyword phrases:
- travelling terus
- proud koncoku
- great kalian semua
- chattingane ilang
- baru aja launching
We acquire 40,788,384 raw tweets. We apply first stage pre-processing tasks such as:
- remove duplicate tweets,
- remove tweets with token length less than 5,
- remove multiple space,
- convert emoticon,
- convert all tweets to lower case.
After the first stage pre-processing, we obtain 17,385,773 tweets. In the second stage pre-processing, we do the following pre-processing tasks:
- split the tweets into sentences,
- remove sentences with token length less than 4,
- convert ‘@username’ to ‘@USER’,
- convert URL to HTTPURL.
Finally, we have 28,121,693 sentences for the training process. This pretraining data will not be opened to public due to Twitter policy.
