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...

This paper introduces PersPred, the first manually elaborated syntactic and semantic database for Persian Complex Predicates (CPs). Beside their theoretical interest, Persian CPs constitute an important challenge in Persian lexicography and for NLP. The first delivery, PersPred 11, contains 700 CPs, for which 22 fields of lexical, syntactic and semantic information are encoded. The semantic cla...

One summer evening in 2004 our 11 year old son went to bed after various delaying tactics—arguments about friends who stay up later, forgetting to brush teeth, coming down for a drink of water. Shortly afterwards the dining room door opened. In he came, cupping his bleeding nose in one hand as he gripped the bridge of the nose with the other. We led him to the kitchen sink to help him clean up ...

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...

Currently, carpet companies assess the quality of their products based on their appearance retention capabilities. For this, carpet samples with different degrees of wear after a traffic exposure simulation process are rated with wear labels by human experts. Experts compare changes in appearance in the worn samples to samples with original appearance. This process is subjective and humans can ...

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...

OBJECTIVE The most commonly used instrument for the research and treatment of excessive internet use is Young's Internet Addiction Test (IAT). While the IAT has been translated to several languages (including Persian) and has demonstrated good psychometric properties across several independent studies, there is still a room for alternative assessment instruments. This study reports a validation...

The Indo-Persian state secretary has occupied center stage in the emerging discourse on bureaucracy, administration and the political formation of the Mughal state. The status and role of the munsh? (the IndoPersian state secretary) within the Mughal bureaucratic structure in 17th and 18th century have formed the basis of recent historical analysis. Scholarship on the Indo-Persian munsh? have b...

Finding an appropriate dataset for natural language processing applications is one of the main challenges for researches of this field. This issue is more problematic in Non-Latin languages especially Persian language. Access to an appropriate dataset that can be used in development of practical programs in language processing field, helps us to validate the obtained results and provide the fea...
