چکیده (انگلیسی):

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, semivowelised
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.
