This report describes the Shiraz project MT prototype for a Persian to English machine translation system using typed feature structures and unification. An overview of the linguistic properties of Persian is presented and the morphological and syntactic grammars developed within the Shiraz project are discussed. The underlying model for the system is a layered chart, capable of representing he...

This paper discusses a methodology for handwritten character recognition applying feature subset selection to reduce number of features. Its novelty lies in the use of a genetic algorithm for the preparation of input data for a support vector machine which is employed to recognize the handwritten Persian digits in particular. Comprehensive experiments on handwritten Persian digits demonstrate t...

In this study, a system for Iranian traditional music Dastgah classification is presented. Persian music is based upon a set of seven major Dastgahs. The Dastgah in Persian music is similar to western musical scales and also Maqams in Turkish and Arabic music. Fuzzy logic type 2 as the basic part of our system has been used for modeling the uncertainty of tuning the scale steps of each Dastgah....

We present two dependency parsers for Persian, MaltParser and MSTParser, trained on the Uppsala PErsian Dependency Treebank. The treebank consists of 1,000 sentences today. Its annotation scheme is based on Stanford Typed Dependencies (STD) extended for Persian with regard to object marking and light verb contructions. The parsers and the treebank are developed simultanously in a bootstrapping ...

Polycystic kidney disease was first described in adult male and female long-haired, Persian-type cats in the late 1960’s. In 1996, the disorder was shown to be inherited as an autosomal dominant trait in a family of Persian cats. Both male and female cats were affected. In affected × unaffected crosses, 42% of offspring were affected and 58% were unaffected. In affected × affected crosses, 73% ...

In this paper, we describe an ongoing research to develop an HPSGbased treebank for Persian. To this aim, we use a bootstrapping approach for the data annotation. In the rst step, a set of seed rules are de ned as regular expressions in the CLaRK system. Then, the data is shallow processed with this set of rules. In the next step, a human annotator completes the annotation of sentences manually...

In this paper, we investigate the problem of Ezafe recognition in Persian language. Ezafe is an unstressed vowel that is usually not written, but is intelligently recognized and pronounced by human. Ezafe marker can be placed into noun phrases, adjective phrases and some prepositional phrases linking the head and modifiers. Ezafe recognition in Persian is indeed a homograph disambiguation probl...

Most data on the Web is in the form of text or image. Finding desired data on the Web in a timely and cost-effective way is a problem of wide interest. In the last several years, many search engines have been created to help Web users find desired information. In this paper we present a new technique to eliminate the affixes and their effects on recognizing similar Persian documents. Reviewing ...

Bilingual parallel corpora are very important in various filed of natural language processing (NLP). The quality of a Statistical Machine Translation (SMT) system strongly dependent upon the amount of training data. For low resource language pairs such as Persian-English, there are not enough parallel sentences to build an accurate SMT system. This paper describes a new approach to use the Wiki...

Polycystic kidney disease in Persian cats culminates in chronic renal failure after a variable clinical course. An affected 6-year-old Persian cat was used to establish a colony of cats with polycystic kidney disease. In affected cats, cysts could be detected by ultrasonography as early as 7 weeks of age. Absence of cysts on ultrasound examination at 6 months of age was correlated with absence ...
