— Topic classification of texts is one of the most interesting challenges in Natural Language Processing (NLP). Topic classifiers commonly use a bag-of-words approach, in which the classifier uses (and is trained with) selected terms from the input texts. In this work we present techniques based on graph similarity to classify short texts by topic. In our classifier we build graphs from the inp...

Ultrasound is one of the most widely used multipurpose imaging modalities that is ideal for monitoring and diagnosing early pregnancy events. The first sign and measurable element of an early pregnancy is the Gestational Sac (GS). Currently, the size of GS is manually measured from an ultrasound image of the GS. This paper argues that the Mean Sac Diameter (MSD) derived from the manual measurem...

Automated extraction of information from natural language texts remains a largely unsolved problem. Scientific texts in general and mathematical texts in particular, are characterised by the use of complex language constructs, often requiring extensive background knowledge for comprehension. Fortunately, many mathematical texts contain special types of text elements, such as definitions and the...

Moving in line with the postulation that metadiscourse (MD) markers help transform a dry and tortuous piece of text into a coherent and reader-friendly one, the researchers in the current study attempted to investigate the effect different metadiscourse markers might have on Iranian EFL learners’ perception of written texts. To this end, 120 undergraduate English students were given three diffe...

The human retrotransposon with the highest copy number is the Alu element. The human genome contains over one million Alu elements that collectively account for over ten percent of our DNA. Full-length Alu elements are randomly distributed throughout the genome in both forward and reverse orientations. However, full-length widely spaced Alu pairs having two Alus in the same (direct) orientation...

This study is the result of an attempt to investigate the differences between the Persian translated drama text (page) of each English drama text with its performance on the stage (stage) in Iran. In other words, the present researchers tried to find the implemented changes in page which make it real on the stage in the target language and culture in order to show that in drama translating and ...

this study was an attempt to investigate the realization of catford’s shifts in the farsi translation of english psychology texts, a product-oriented point of view, shedding light on the areas farsi is different english. inspired by a study conducted by khorshidi (2010), the two questions raised in the study sought to detect the kinds of shifts applied in the translation of english psychology t...
