Abstract
Arabic stemming is a technique to find the stem or lexical root for Arabic words through the process of eliminating affixes (preffixes, infixes and suffixes) attached to their roots. Several approaches have been implemented to generate the stem of Arabic words according to a certain level of analysis, i.e., root-based approach, stem-based approach and statistical approach. Arabic language is a Semitic language which means that it is a derivational rather than a concatinative language. In this study we designed and implemented an Arabic triliteral Morphological Analyser that is capable of analysing the classical and Modern Standard Arabic (MSA) effectively with the capability of analysing vowelised, semi-vowelised and nonvowelised text. The system is integratable with other applications so that vast number of people can get benfited from. One shortcomming for the developed system is that the output obtained from the morphological analyser may contain several alternative solutions which leads to extraction ambiguity.
Highlights
Arabic verbs are constructed on the root ; >=ـــthat uses three consonants ف, عand لthat is know by Arabic grammarians as Morphological Balance (MB), the result of mapping root letters to MB forms is verbal or nominal stems
In this study we propose an algorithm for word analyser that accepts the non-article trilateral words and finds out their roots
When the system is integrated with some applications like Machine Translation (MT) where the template affects the Part of Speech (POS) (Part of Speech (POS) is the method of classification of words according to their meaning, functions and categories such as noun, verb and adjective
Summary
Arabic verbs are constructed on the root ; >=ـــthat uses three consonants ف, عand لthat is know by Arabic grammarians as Morphological Balance (MB), the result of mapping root letters to MB forms is verbal or nominal stems. The Arabic three consonants in the root-verb (; )>=ـــare represented as (C1), (C2) and (C3) respectively, while the supscript followed the consonant represents the sequence of these consonants the multifarious vowels and affixes are attached to the root verbs to create the desired inflection of the meaning. Arabic roots can be classified into two classes as shown in Fig. 2; the vowelized roots and non-vowelized Roots (Al-Omari, 1995; Al-Dahdah, 1985). This classification was made in accordance with the availability of the Arabic vowels in the roots
