a bilingual corpus is considered as a very important knowledge source and an inevitable requirement for many natural language processing (nlp) applications in which two languages are involved. for some languages such as persian, lack of such resources is much more significant. several applications, including statistical and example-based machine translation needs bilingual corpora, in which lar...

Entity extraction is considered as a fundamental step in many text mining applications such as machine translation, text summarization and text categorization. However, the major challenging issue in extracting the entity from a sentence is the ambiguity problem, namely lexical ambiguity. While a human has a cognitive capability to resolve the meaning easily based on his/her knowledge, it is ve...

Generally, Intelligent Tutoring Systems (ITSs) rely heavily on the hand-construction and design of the domain knowledge provided for learners. In this paper we attempt to illustrate a central role that knowledge representation can play in automating crucial aspects of ITS design and implementation. We focus on the treatment of English learners’ lexical errors. Specifically, we describe a system...

Metaphor and other forms of non-literal language are essential parts of language which have direct bearing on theories of lexical semantics. Neither narrow theories of lexical semantics, nor theories relying solely on world knowledge are sufficient to account for our ability to generate and interpret non-literal language. This paper presents an emerging approach that may provide such an account...

Current models of word recognition differ on the potential influence of lexical knowledge on sublexical processes. The present study addresses this issue through a paradigm based on the perceptual ‘‘migration’’ of linguistic units between two stimuli presented simultaneously, resulting in an illusory percept. For example, ‘‘kinrtrorverrsy’’ and ‘‘bosrglorrarfe’’ were played at the same time, wi...

This paper describes preliminary work concerning the creation of a Framework to aid in lexical semantic resource construction. The Framework consists of 9 stages during which various lexical resources are collected, studied, and combined into a single combinatory lexical resource. To evaluate the general Framework it was applied to a small set of English and Arabic resources, automatically comb...

Taking the position that writing can be an important skill to foster knowledge building pedagogy, this article explores vocabulary as a supportive tool for this purpose. Having this in mind, a compilation of conceptually loaded vocabularies pertaining to seven discourse communities was developed, two of which were given to a group of L2 writers to investigate the implications of phraseology for...

Although the semantic analysis and the grammatical distribution are treated as separate issues in linguistic theories, there is a close interconnection between the two in that the differences in the lexical meanings are often realized at the levels both of the grammatical function and of the lexical collocation. This is the basic assumption utilized when we design and develop Knowledge Base of ...
