The existing applications in Natural Language Process (NLP) weren’t reliable. Indeed, many complex phenomena are not treated completely such as relatives, juxtaposition, ellipsis and the coordination, essentially for Arabic grammar. In fact, the problems encountered relate to the choice of the formalism and the parser validating the constructed grammar. Therefore, our work aims to appreciate th...

The knowledge engineering effort associated with defining grammar systems can become a barrier for the practical use of such systems. Existing grammar and rule induction algorithms offer rather limited support for discovering context-sensitive graph grammar rules as required by some applications in the domain of engineering design. For this task the present work proposes a rule induction method...

We have developed a rule learning system that employed Grammar Based Genetic Program ming for knowledge discovery from databases A grammar is used as a template for the rule format Grammar Based Genetic Program ming can guide the evolution and the discovery of meaningful rules The technique Token Competition is used to achieve the learning of multiple rules simultaneously We have applied the ap...

This paper explores the usefulness of a technique from software engineering, namely code instrumentation, for the development of large-scale natural language grammars. Information about the usage of grammar rules in test sentences is used to detect untested rules, redundant test sentences, and likely causes of overgeneration. Results show that less than half of a large-coverage grammar for Germ...

This study aimed to identify the portions of teaching materials for English classes in Iran’s high schools. The efficiency of these materials was evaluated by (a) eliciting the teachers’ perception of the materials to identify their distribution portions and (b) studying the teachers’ satisfaction to identify whether the materials were successful to develop the EFL teachers’ knowledge and skill...

Syntactic analysis is a fundamental phase in NLP (Natural Language Processing) domain. This phase occurs in several applications and at different levels. Moreover, it wasn’t spilled in domain research, especially for Arabic language. In fact, most of researchers working on Arabic language treated simple structures and neglected complicated ones such as relatives, coordination, ellipse and juxta...

INKA is a natural language interface to facilitate knowledge acquisition during expert system development for electronic instrument trouble-thooting. The expert system design methodology develops a domain definition, called GLIB, in the form of a semantic grammar. This grammar format enables GLIB to be used with the INGLISH interface, which constrains users to create statements within a subset ...

Although the Semantic web is steadily gaining in popularity, it remains a mystery to a large percentage of Internet users. This can be attributed to the complexity of the technologies that form its core. Creating intuitive interfaces which completely abstract the technologies underneath, is one way to solve this problem. A contrasting approach is to ease the user into understanding the technolo...

The study of English language teachers’ cognitions and its relationship to teachers’ classroom practices have recently been the focus of language teaching and teacher education (Borg, 2006 & 2010). However, rarely have the studies delved into teachers’ knowledge about grammar (reviewed by Borg, 2001) or investigated the relationships between teachers’ knowledge about grammar and teachers’ actio...
