ElixirFM is its high-level im- plementation that reuses and extends the Functional Morphology library for Haskell. Inflection and derivation are modeled in terms of paradigms, grammatical categories, lexemes and word classes. The computation of analysis or generation is conceptually distinguished from the general-purpose linguistic model. The lexicon of ElixirFM is designed with respect to abstraction, yet is no more com- plicated than printed dictionaries. It is derived from the open-source Buckwalter lexicon and is enhanced with information sourcing from the syntactic annotations of the Prague Arabic DependencyTreebank. MorphoTrees is the idea of building effective and intuitive hierarchies over the in- formation provided by computational morphological systems. MorphoTrees are imple- mentedforArabicasanextensiontotheTrEdannotationenvironmentbasedonPerl. Encode Arabic libraries for Haskell and Perl serve for processing the non-trivial and multi-purpose ArabT X notation that encodes Arabic orthographies and phonetic tran- E scriptions in parallel.
