Description

Japanese morphological analyzer, Kuromoji doesn't have a capability to decompose every Japanese Katakana compound tokens to sub-tokens. It seems that some Katakana tokens can be decomposed, but it cannot be applied every Katakana compound tokens. For instance, "トートバッグ(tote bag)" and "ショルダーバッグ" don't decompose into "トート バッグ" and "ショルダー バッグ" although the IPA dictionary has "バッグ" in its entry. I would like to apply the decompose feature to every Katakana tokens if the sub-tokens are in the dictionary or add the capability to force apply the decompose feature to every Katakana tokens.
