negation has many complicated forms and can be represented in a variety of ways. some sentences have explicit negation items and some other sentences convey the notion of negation without having any explicit negation item. negative polarity items (npis) are expressions that need to a negative context to be grammatically correct, and their meanings are compatible with negative sentences and are ...

Plagiarism detection is defined as automatic identification of reused text materials. General availability of the internet and easy access to textual information enhances the need for automated plagiarism detection. In this regard, different algorithms have been proposed to perform the task of plagiarism detection in text documents. Due to drawbacks and inefficiency of traditional methods and l...

this study examined the phonetic characteristics of persian sentence stress produced by native mandarin chinese speakers. we compared the phonetic correlates of sentence stress, namely fundamental frequency (f0), vowel duration, and vowel intensity in the production of 8 mandarin chinese speakers and 8 native persian speakers. results indicated that mandarin chinese speakers of persian could di...

The current research aims at exploring and comparing the semantic frames of motion verbs in English Persian. In pursuit this goal, novel Animal farm by G. Orwell (1945) was selected compared with its Persian translation, Qale heyvanat (Atefi, 2010). sentences including were primarily extracted from then a comparison made between each sentence counterpart. Afterwards, obtained FrameNet database....

Although widely-studied in recent years, Language Identification (LID) systems for determining the language of input texts often fail to discriminate between similar languages like Croatian-Serbian and Malay-Indonesian. This has brought attention to the task of discriminating similar languages, varieties and dialects – including a recent shared task [3]. Persian (also known as Farsi) and Dari (...

This paper presents an ongoing project whose goal is to create a freely available dependency treebank for Persian. The data is taken from the Bijankhan corpus, which is already annotated for parts of speech, and a syntactic dependency annotation based on the Stanford Typed Dependencies is added through a bootstrapping procedure involving the opensource dependency parser MaltParser. We report pr...

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 ...

This paper describes the latest developments in the PeEn-SMT system, specifically covering experiments with Grafix, an APE component developed for PeEn-SMT. The success of well-designed SMT systems has made this approach one of the most popular MT approaches. However, MT output is often seriously grammatically incorrect. This is more prevalent in SMT since this approach is not language-specific...
