Historical text presents numerous challenges for contemporary natural language processing techniques. In particular, the absence of consistent orthographic conventions in historical text presents difficulties for any system requiring reference to a static lexicon accessed by orthographic form. In this paper, we present three methods for associating unknown historical word forms with synchronica...

This paper presents a rule-based approach for finding out the stems from text in Bengali, a resource-poor language. It starts by introducing the concept of orthographic syllable, the basic orthographic unit of Bengali. Then it discusses the morphological structure of the tokens for different parts of speech, formalizes the inflection rule constructs and formulates a quantitative ranking measure...

The process of recognizing printed words has been studied for many years, yielding several important models of word recognition in reading. These models provide a variety of descriptions of the word recognition process, given different assumptions regarding the structure of the lexical system. Yet what all models have in common is the recognition that reading involves the processing of orthogra...

Transliteration is the process of proper name translation based on pronunciation. It is an important process in many multilingual natural language tasks. A common and essential component of transliteration approaches is a verification mechanism that tests if the two names in different languages are translations of each other. Although many transliteration systems have verification as a componen...

The Arabic alphabetical orthographic system has various unique features that include the existence of emphatic phonemic letters. These represent several pairs of letters that share a phonological similarity and use the same parts of the articulation system. The phonological and articulatory similarities between these letters lead to spelling errors where the subject tends to produce a pseudohom...

Spelling a word involves the retrieval of information about the word's letters and their order from long-term memory as well as the maintenance and processing of this information by working memory in preparation for serial production by the motor system. While it is known that brain lesions may selectively affect orthographic long-term memory and working memory processes, relatively little is k...

Previous studies have found that children with reading difficulties need more exposures to acquire the representations needed to support fluent reading than typically developing readers (e.g., Ehri and Saltmarsh, 1995). Building on existing orthographic learning paradigms, we report on an investigation of orthographic learning in poor readers using a new learning task tracking both the accuracy...
