Splits Japanese text into tokens.
Tokenization is an important pre-processing step and prepares text data for subsequent analysis, transliteration, text mining or natural language processing tasks.
Unlike English or French, there are no spaces to mark word boundaries in Japanese. Splitting Japanese text into tokens is then more challenging.
Based on the IPADIC dictionary, tJapaneseTokenize deduces where word boundaries exist and adds a space to separate tokens.
The IPADIC dictionary was developed by the Information-Technology Promotion Agency of Japan (IPA). This dictionary is based on the IPA corpus and is the most widely used dictionary for Japanese tokenization.
