| <p> Kuromoji is a morphological analyzer for Japanese text. </p> |
| <p> This module provides support for Japanese text analysis, including features such as part-of-speech tagging, lemmatization, and compound word analysis. </p> |
| <p> For an introduction to Lucene's analysis API, see the <xref:Lucene.Net.Analysis> package documentation. </p> |
