Résumé

Morphology knowledge is relevant in language learning, information retrieval and natural language processing. Derivation lexicons are organized and comprehensive collections of the morphological variants of a language's vocabulary. These lexicons can be developed either through analysis-based synthesis of large text corpora or through synthesis of surface forms from roots, stems, lemmas and morphological rules. Much of the research attempted in developing derivation lexicon for Indo-European languages, which are concatenative, focus on analysis-based synthesis, as they do have well-developed preprocessing tools and organized text corpora. However, the methods for these languages are not appropriate for non-concatenative languages such as Semitic languages. Moreover, most of the Semitic languages, except Arabic and Hebrew, do not have well-developed text corpora and language processing tools. Hence, a novel approach that can cater for the root-pattern and rich morphology of these languages is necessary. This paper is therefore a comprehensive survey of the literature, an analysis motivating an innovative and generic morphological synthesis approach with illustrated architecture. It is part of a larger project tailored for designing an innovative, generic, approach to derivation lexicon development for Semitic languages.
