Raudikko is Java library for performing morphological analysis on Finnish language. Raudikko uses Voikko's morphology files and is based on Voikko, but unlike Voikko's Java-interface, it is implemented purely in Java and needs no native libraries. Raudikko is also quite a bit faster than Voikko's Java-interface.
Add dependency to your build file:
implementation("fi.evident.raudikko:raudikko:0.1.4")Create an analyzer and use it to produce Analysis-objects for given words:
// First load and compile the morphology. This is a relatively expensive operation
// that should be done only once. The loaded morphology is immutable and can be shared.
Morphology morphology = Morphology.loadBundled();
// Create an analyzer from the morphology. Creating an analyzer is a cheap operation.
// Analyzers have some cached state and can't be shared between different threads.
Analyzer analyzer = morphology.newAnalyzer();
// Analyze some words
System.out.println(analyzer.analyze("kissoittansa"));
System.out.println(analyzer.analyze("kahdellakymmenelläseitsemällä"));Raudikko is carefully tested against Voikko, making sure that the output of Raudikko and Voikko agree for all inputs. The below table lists the version of Voikko that Raudikko is tests against.
| Raudikko version | Voikko version | Morphology |

| 0.1.2 | 4.3 | 9f0d3d |
| 0.1.3 | 4.3 | 9f0d3d |

Most of Raudikko's code is based heavily on Voikko and the used morphology files come directly from Voikko. None of this would be possible without the great work of Harri Pitkänen and other contributors to Voikko.
