In this paper I present the prepositional system of Persian. I show that Persian prepositions can be divided into three classes (Class 1, Class 2a and Class 2b) which exhibit distinct syntactic behavior. Then I examine the question of the categorial status of Class 2 prepositions and demonstrate that they are not to be regarded as nouns. Finally I present the extended PP projection of Persian s...

In order to facilitate sentiment analysis of Persian text, we’ve designed and implemented an algorithm which aims to detect words with negative polarity. Currently most sentiment analysis algorithms depend mainly on polarity datasets. However, since negative prefixes in Persian are only attached to a semantically positive base (shaghagi, 2002), we have incorporated a negative prefix detection t...

Because of the scarcity of observational data, existing estimates of the heat and water budgets of the Persian Gulf are rather uncertain. This uncertainty leaves open the fundamental question ofwhether this water body is a net heat source or a net heat sink to the atmosphere. Previous regional modeling studies either used specified surface fluxes to simulate the hydrodynamics of the Gulf or pre...

BACKGROUND During the 1990-1991 Gulf War, approximately 700,000 U.S. troops were deployed to the Persian Gulf theater of operations. Of that number, approximately 100,000 have presented medical complaints through various registry and examination programs. OBJECTIVES Widespread symptomatic illness without defining physical features has been reported among veterans of the 1991 Gulf War. We asce...

With the rise of the Web 2.0, collaboratively constructed language resources are rivalling expert-built lexicons. The collaborative construction process of these resources is driven by what is called the “Wisdom of Crowds” phenomenon, which offers very promising research opportunities in the context of electronic lexicography. The vast number and broad diversity of authors yield, for instance, ...

The reporting of pain was compared for U.K. Persian Gulf War veterans, veterans from the Bosnian conflict, and personnel employed in the military at the time of the Persian Gulf War but not deployed (era comparison group). Pain manikins were used to assess the prevalence of the reporting of pain in different body sites and the prevalence of the reporting of widespread pain, in relation to compa...
