Unsupervised Morphology Induction Using Morfessor

  • Conference paper
Finite-State Methods and Natural Language Processing (FSMNLP 2005)

Part of the book series: Lecture Notes in Computer Science ((LNAI,volume 4002))

Abstract

We present Morfessor, an unsupervised algorithm and software that induces a simple morphology of a natural language from a large corpus. Morfessor simultaneously builds a morph lexicon and represents the corpus with the induced lexicon using a probabilistic maximum a posteriori model.
