A lot of work has been done in the field of natural language processing (NLP) for ARABIC. Few researchers have tried hard to apply on ARABIC the methods of computational linguistics, as for example, Definite Clause Grammar (DCG) [I] and Augmented Transition Networks (ATN) [2]. Because there is not a modern linguistic model for ARABIC grammar within the frame of computational linguistics, the re...

This paper discusses a novel probabilistic synchronous TAG formalism, synchronous Tree Substitution Grammar with sister adjunction (TSG+SA). We use it to parse a language for which there is no training data, by leveraging off a second, related language for which there is abundant training data. The grammar for the resource-rich side is automatically extracted from a treebank; the grammar on the...

Machine translation engines draw on various types of databases. This paper is concerned with Arabic as a source or target language, and focuses on lexical databases. The non-concatenative nature of Arabic morphology, the complex structure of Arabic word-forms, and the general use of vowel-free writing present a real challenge to NLP developers. We show here how and why a stem-grounded lexical d...

We describe a Slot Grammar (SG) parser for Arabic, ASG, and new features of SG designed to accommodate Arabic as well as the European languages for which SGs have been built. We focus on the integration of BAMA with ASG, and on a new, expressive SG grammar formalism, SGF, and illustrate how SGF is used to advantage in ASG.

The construction of an HPSG grammar (Headdriven Phrase Structure Grammar) treating Arabic specificities is not an easy task. In fact, several syntactic phenomena must be taken into account. Thus, the main objective of this work is to construct an Arabic HPSG grammar based on a proposed type hierarchy that categorizes Arabic words. In fact, some adaptations were introduced to HPSG, at the level ...

unlike the languages we know, some of the arabic sentences form without any verbs. arab grammarians call these sentences, which contain a subject and a predicate without any linking verbs, nominal sentences. examining theses sentences indicates that their predicate is composed of one of the following words or structures: 1. noun, 2. prepositional phrase, 3. an adverb of time or place, 4. a nomi...

The research focus in our paper is twofold: (a) to examine the extent to which simple Arabic sentence structures comply with the Government and Binding Theory (GB), and (b) to implement a simple Arabic Context Free Grammar (CFG) parser to analyze input sentence structures to improve some Arabic Natural Language Processing (ANLP) Applications. Here we present a parser that employs Chomsky’s Gove...

Muslims believe that the The Holy Quran is the message of God Almighty which has been transmitted to His messenger, Prophet Mohammad (PBUH), through revelation in the Arabic language. This Holy book has been translated into many languages, including English. Although the content of the The Holy Quran has been translated into the English language, few studies have been conducted to explore the b...
