In this paper a new method for automatic word clustering is presented. We used this method for building n-gram language models for Persian continuous speech recognition (CSR) systems. In this method, each word is specified by a feature vector that represents the statistics of parts of speech (POS) of that word. The feature vectors are clustered by k-means algorithm. Using this method causes a r...

This paper presents a novel method to extract the collocations of the Persian language using a parallel corpus. The method is applicable having a parallel corpus between a target language and any other high-resource one. Without the need for an accurate parser for the target side, it aims to parse the sentences to capture long distance collocations and to generate more precise results. A traini...

Persian language is transcribed in a lossy manner as it does not, as a rule, encode vowel information. This renders the use of the written script suboptimal for language models for speech applications or for statistical machine translation. It also causes the text-to-speech synthesis from a Persian script input to be a one-to-many operation. In our previous work, we introduced an augmented tran...

Increasing the domain of locality by using Tree Adjoining Grammars (TAG) caused some applications, such as machine translation, to employ it for the disambiguation process. Successful experiments of employing TAG in French-English and Korean-English machine translation encouraged us to use it for another language pairs with very divergent properties, Persian and English. Using Synchronous TAG (...

following the formation of the persian empire by cyrus the great and its extension by darius i, from indus river in india to nile in egypt, persian kings felt that there is a need to use an international language to be understandable by all nations of this great empire. this need was greater when they sent orders and messages to these different nations. when darius i defeated his enemies and su...

INTRODUCTION Hearing loss from birth up to the age of 3 years has a negative effect on speech/language development and results in sensory, cognitive, emotional, and academic defects in adulthood by causing delayed development of communicative-linguistic abilities. The present study was performed in order to assess the effect of early intervention on language development in Persian children aged...

Parallel data are an important part of a reliable Statistical Machine Translation (SMT) system. The more of these data are available, the better the quality of the SMT system. However, for some language pairs such as Persian-English, parallel sources of this kind are scarce. In this paper, a bidirectional method is proposed to extract parallel sentences from English and Persian document aligned...

In linguistics, stemming is the operation of reducing words to their more general form, which is called the ‘stem’. Stemming is an important step in information retrieval systems, natural language processing, and text mining. Information retrieval systems are evaluated by metrics like precision and recall and the fundamental superiority of an information retrieval system over another one is mea...

a curriculum deals with all the aspects of language learning including experience and purpose of learning, evaluation, and teacher-student relationship. an accurately planned curriculum for instruction can basically guarantee the success of an educational course. the present study is aimed at introducing nation & macalister language curriculum design (2010). doing so, the stages and principles ...

The present study serves as an attempt to shed light on any probable effect of self-regulation and motivation on the writing performance of Persian EFL language learners. To achieve the purpose, two questionnaires (on self-regulation and motivation) were employed as study tools and were distributed among 80 Persian EFL language learners. They were also required to write an essay. Analyzing the ...
