Ezafe construction is an idiosyncratic phenomenon in the Persian language. It is a good indicator for phrase boundaries and dependency relations but mostly does not appear in the text. In this paper, we show that adding information about Ezafe construction can give 4.6% relative improvement in dependency parsing and 9% relative improvement in shallow parsing. For evaluation purposes, Ezafe tags...

In this paper we present a rather novel unsupervised method for part of speech (below POS) disambiguation which has been applied to Persian. This method known as Iterative Improved Feedback (IIF) Model, which is a heuristic one, uses only a raw corpus of Persian as well as all possible tags for every word in that corpus as input. During the process of tagging, the algorithm passes through sever...

In this paper we present and justify methodological principles and syntactic criteria to design an annotation scheme for a Persian Treebank. The main approaches to the annotation of Treebanks are presented in order to account for taken decisions. After examining these approaches, and taking into account the syntactic characteristics of Persian, the most appropriate one will be selected and its ...

An 8-year-old female Persian cat with a gait disorder was brought to our hospital. Pelvic limb mobility had gradually reduced over the preceding 3 months, then rapidly deteriorated 2 weeks before consultation. Signs also occurred in the thoracic limbs. With a tentative diagnosis of neural disease, magnetic resonance imaging and computed tomography were performed. T1-weighted imaging showed isoi...

One-year-old male Persian cat presented with multiple fractures and no known traumatic history. Marked decrease of bone radiopacity and thin cortices of all long bones were identified on radiography. Tentative diagnosis was osteogenesis imperfecta, a congenital disorder characterized by fragile bone. To determine bone mineral density (BMD), quantitative computed tomography (QCT) was performed. ...

Evolution of languages has always been of interest to linguists.  In this paper we study  the natural progress of the syllable structure from Old  Persian  (O.P)  to Middle Persian (Mi.P) and up to the Modern Persian (Mo.P). For this purpose all the words containing consonant sequences are collected from specific sources of each  of these  languages,  and then  analysed  according to the syllab...

Although the connection between head and stomach and hence the condition known as "gastric headache" was well known to the ancients, it has received little attention since the early 20th century. Herein, we review the teachings of the medieval Persian physicians about the gastric headache along with the related signs, symptoms, types and causes. The medieval Persian scholars adopted the main id...
