Morphological parsing

The goal of morphological parsing is to find out what morphemes a given word is built from. It should be able to distinguish between orthographic rules and morphological rules.

The generally accepted approach to morphological parsing is through a FST that inputs words and outputs their stem and modifiers. This FST is initially created through algorithmic parsing of some word source, such as a dictionary complete with modifier markups.

Another approach is an indexed lookup through a constructed Radix tree. This is not an often-taken route because it breaks down for morphologically complex languages.
