Moranapho: a multilingual system for morphological analysis based on formal analogy

Within the framework of Morpho Challenge 2009, we developed an unsupervised morphological analysis system based on formal analogies between words. After the evaluation campaign, we took time to correct some problems in our system and to analyze its main characteristics. This paper focusses on the knowledge we acquired during this post-mortem exercise. We hope this work will contribute to show that formal analogy is not only a viable solution, but is also a competitive one. MOTS-CLÉS : analyse morphologique non supervisée, analogie formelle, approche à base de graphes.
