Abstract

Spellchecker is software that analyzes possible
misspellings in the text. It is the process of detecting and
sometimes providing some suggestions for incorrectly spelled
words in a text. If dictionary of spell checker is larger than
higher is the error detection and error correction rate. Though
considerable work has been done in English language but not
much work has been done in regional languages of India
including Punjabi and Hindi. Punjabi is the official language
of Punjab state in India Punjabi is world’s 12th most widely
spoken language In Punjabi language, there is very small
amount of work is completed in this region.. Hindi is the
official language of 11 vowels and 33 consonants. Hindi is
also the third most spoken language in the world. A few work
is done in Punjabi-Hindi spell detection and correction field
and it is not easy task to identify errors in Punjabi-Hindi text.
The spell checker systems are online available but as not
stand-alone applications. The only available spell checker for
Punjabi is “Akhar†â€Raftaar†and “Sudhaarâ€. “Akhar†is paid
software that is not available free for its use to everybody and
“Sudhaar†spell checker is a desktop application Some paid
Hindi spell checker software’s are also online available.
“Hinspell†& “Hinkhoj†are available spell checkers for Hindi
language but a lot of improvement is needed. NLP (Natural
language processing) is a field of computer science concerned
with interaction between computer and human language. We
have developed a combined spell checker and error correcting
system for both Punjabi and Hindi Language. We used hybrid
approach to implement the Spelling checking and Correcting
System. The proposed system use hybrid approach which s a
combination of various approaches like rule based approach,
dictionary lookup approach , edit distance approach and NGram
approach. Proposed system is tested with various inputs
collected from different sources and results are found very
accurate than that of existing system.
