R package for automatic Korean word spacing.
Word spacing is one of the important parts of the preprocessing of Korean text analysis. Accurate spacing greatly affects the accuracy of subsequent text analysis. KoSpacing has fairly accurate automatic word spacing performance, especially good for online text originated from SNS.
KoSpacing is based on Deep Learning model trained from large corpus(more than 100 million NEWS articles from Chan-Yub Park).
| Test Set | Accuracy |
|---|---|
| Sejong(colloquial style) Corpus(1M) | 97.1% |
| OOOO(literary style) Corpus(3M) | 94.3% |
- Accuracy = # correctly spaced characters/# characters in the test data.
- Might be increased performance if normalize compound words.
