Linguistic resources are very important to any natural language processing task. Unfortunately, the manual construction of these resources is laborious and time-consuming. The use of annotated corpora as a knowledge database might be a solution to a fast construction of a grammar for a given language. In this paper, we present our method to automatically induce a syntactic grammar from an Arabi...

Arabic phonetics has been part of the study of Arabic language since the 7 th century CE. The great works by Al-Khali:l, "Kita:b al-'Ayn", and Si:bawayh, author of the first Arabic grammar book "al-kita:b" (i.e., "The Book") are the two cornerstones of this field. The early Arab grammarians knew phonetics quite well, although they mixed it with phonology, but interest in phonetics has remained ...

We present a comparative analysis of relative clauses in Hindi and Arabic in the tradition of the Paninian Grammar Framework (Bharati et al., 1996b) which leads to deriving a common logical form for equivalent sentences. Parallels are drawn between the Hindi co-relative construction and resumptive pronouns in Arabic. The analysis arises from the development of lexicalised dependency grammars fo...

The aim of this paper is to describe a technique for identifying the sources of several types of syntactic ambiguity in Arabic Sentences with a single parse only. Normally, any sentence with two or more structural representations is said to be syntactically ambiguous. However, Arabic sentences with only one structural representation may be ambiguous. Our technique for identifying Syntactic Ambi...

In this paper, we describe two approaches to extending syntactic constraints in the Hierarchical Phrase-Based (HPB) Statistical Machine Translation (SMT) model using Combinatory Categorial Grammar (CCG). These extensions target the limitations of previous syntax-augmented HPB SMT systems which limit the coverage of the syntactic constraints applied. We present experiments on Arabic–English and ...

The paper proposes a treatment of relative sentences within the framework of Head-driven Phrase Structure Grammar (HPSG). Relative sentences are considered as a rather delicate linguistic phenomenon and not explored enough by Arabic researchers. In an attempt to deal with this phenomenon, we propose in this paper a study about different forms of relative clauses and the interaction of relatives...

We describe the adaptation for Arabic of the grammar-based MedSLT medical speech system. The system supports simple medical diagnosis questions about headaches using vocabulary of 322 words. We show that the MedSLT architecture based on motivated general grammars produces very good results, with a limited effort. Based on the grammars for other languages covered by the system, it is in fact ver...

Systemic functional grammar constructs a grammar for the purpose of text analysis to investigate how grammar is used as a means of making meaning. Grammatical metaphor is one of the language phenomena introduced by Halliday (2004) in the framework of functional grammar. The present work focuses on the application of Halliday’s metafunctional framework in health texts of English newspapers. The ...

We describe a process for converting the Penn Arabic Treebank into the CCG formalism. Previous efforts have yielded CCGbanks in English, German, and Turkish, thus opening these languages to the sophisticated computational tools developed for CCG and enabling further cross-linguistic development. Conversion from a context free grammar treebank to a CCGbank is a four stage process: head finding, ...

The relative phenomenon is considered as a rather delicate linguistic phenomenon and not explored enough by researchers, especially for the Arabic language. In an attempt to deal with this phenomenon, we propose in this paper a study about different forms of relative clauses. This study will be used for the building of a parser that can process relative sentences. This parser is constructed usi...
