چکیده

This paper presents a fully integrated spelling co-processor for speeding up the character string comparison process. The chip we present is architectured around a banded 2-D systolic array consisting of 69 processors and is able to process more than 2 million of words per second. The high regularity of the chip has been exploited for investigating a design methodology based on the automated generation of a representative subcircuit : the kernel.

A High Performance Systolic Chip for Spelling Correction

This paper presents a fully integrated co-processor for accelerating the character string comparison involved in the spelling correction process. The chip we present is based on a truncated 2-D systolic array of 69 processors and is able to perform up to 1.3 Gops. Real time spelling correction is possible on very large vocabularies since dictionaries of 200,000 items can be processed in only 0....

Design and implementation of Persian spelling detection and correction system based on Semantic

Persian Language has a special feature (grapheme, homophone, and multi-shape clinging characters) in electronic devices. Furthermore, design and implementation of NLP tools for Persian are more challenging than other languages (e.g. English or German). Spelling tools are used widely for editing user texts like emails and text in editors.  Also developing Persian tools will provide Persian progr...

A Unified Approach to Transliteration-based Text Input with Online Spelling Correction

This paper presents an integrated, end-to-end approach to online spelling correction for text input. Online spelling correction refers to the spelling correction as you type, as opposed to post-editing. The online scenario is particularly important for languages that routinely use transliteration-based text input methods, such as Chinese and Japanese, because the desired target characters canno...

Integrated Scoring For Spelling Error Correction, Abbreviation Expansion and Case Restoration in Dirty Text

An increasing number of language and speech applications are gearing towards the use of texts from online sources as input. Despite such rise, not much work can be found in the aspect of integrated approaches for cleaning dirty texts from online sources. This paper presents a mechanism of Integrated Scoring for Spelling error correction, Abbreviation expansion and Case restoration (ISSAC). The ...
