2.ARABIC AND COMPUTATIONAL
LINGUISTICS
</SectionTitle>
    <Paragraph position="0"> As the need increases to a model of A~%BIC, ARABIC linguists try to re-organize the granmlatic system in a way that may help the researchers in the field of computational linguistics. Linguists is traditionally concerned with formal, general, structural models of natural language. Linguists, therefore, have tended to build formal models which allow to capture, as much as possible, the regularities of language and make the most appropriate linguistic generalizations. Little or no attention has been paid to characterize the language itself, ignoring the mechanism that produce it or decipher it.</Paragraph>
    <Paragraph position="1"> So, the researchers spent most of the time in re-building the models given by the linguists. Their aim was to make these models acceptable in computational field (synthesis, generation and translation).</Paragraph>

2.i THE KEY
</SectionTitle>
    <Paragraph position="0"> What is new in this work is that we classified all the noun phrase modifiers into two categories. Category one, noun phrase postmodifiers, in which the ordered sequence of these modifiers is significant and it is the key to construct these noun phrase structures These modifiers are noun complement (NC), adjective (ADJ), apposition (APP) and correlation (COR). Category two which consists mainly from VP modifiers like adverb. The above categorization has given us the ability to focus on each category and finally the NP structures were obtained .</Paragraph>

3. THE NOUN PHRASE STRUCTURES
</SectionTitle>
    <Paragraph position="0"> We have Eight structures covering all the categories of noun phrases. FIVE of these structures are giw~n here.</Paragraph>
    <Paragraph position="1"> The notation used in describing these structures is : null brackets could be repeated but it should exists once at leastdeg Representation is in Chomsky's Normal Form and should be interpreted from right to left The structures given here consist mainly of NOUN (N) as the basic unit and its maximum allowable post-modifier8 whichcould follow it These post-modifiers have a specific sequence which is the key to construct these structures and according to the number of these post-modifiers, the structures vary The NP structures as well as some of the ARABIC categories they constitute, are given in Fig.(1) Example of a simple Arabic verbal sentence is given in Fig.(2) In this example, the object of the sentence has all the post- modifiers given in the structure NPI and It is clear that some of these modifiers have their own embedded structures shown in the embedded rectangles</Paragraph>

4. MODIFICATION
</SectionTitle>
    <Paragraph position="0"> 'MAFOOL MOTLAK' is a special modifier in Arabic which has a different forms depending on its post-modifiers. We have first \[5\] considered its structure as:</Paragraph>
    <Paragraph position="2"> But later on, we have found out that both NC and ADJ can not exist simultaneously and only one of them should exist alone. So, we have split this structure to three structures NP3, NP4 anti NP5 published here.</Paragraph>

CONCLUS ION
</SectionTitle>
    <Paragraph position="0"> We have tried here to present the paper in a frame work showing that the study of computational modeling of ARABIC faces many problems. It is evident that:, the ARABIC possesses a certain symmetry as regards its structure, which leads itself easily to computation. This work is the basis of any further computational processing of ARABIC, leading to semantic analysis and</Paragraph>
