Stemming and Segmentation for Classical Tibetan

Tibetan is a monosyllabic language for which computerized language tools are largely lacking. We describe the development of a syllable stemmer for Tibetan. The stemmer is based on a set of rules that strive to identify the vowel, the core letter of the syllable, and then the other parts. We demonstrate the value of the stemmer with two applications: determining stem similarity of two syllables and word segmentation. Our stemmer is being made available as an open-source tool and word segmentation as a freely-available online tool.
