## Dataset Creation

### Curation Rationale

The dataset was created for [BEST 2010: Word Tokenization Competition](https://thailang.nectec.or.th/archive/indexa290.html?q=node/10) by [NECTEC](https://www.nectec.or.th/).

### Source Data

#### Initial Data Collection and Normalization

[More Information Needed]

#### Who are the source language producers?

Respective authors of the articles, news, encyclopedia and novels

### Annotations

#### Annotation process

Detailed annotation guidelines can be found in `BEST_Guideline_Release1.pdf` as part of the uncompressed files. Word tokenization standard used was [InterBEST2009](http://hltshare.fbk.eu/IWSLT2015/InterBEST2009Guidelines-2.pdf)

#### Who are the annotators?

[More Information Needed]

### Personal and Sensitive Information

All data are curated from public sources. No personal and sensitive information is expected to be included.

## Considerations for Using the Data

### Social Impact of Dataset

- word tokenization dataset from articles, news, encyclopedia and novels

### Discussion of Biases

- texts are relatively formal ones from articles, news, encyclopedia and novels.
- word tokenization standard used was [InterBEST2009](http://hltshare.fbk.eu/IWSLT2015/InterBEST2009Guidelines-2.pdf).

### Other Known Limitations

- some tags unrelated to word tokenization (`<NE>` and `<AB>`) are cleaned out.
- no word boundary provdied for the test set
