This is demonstrated in Figures
2-4. Recent advances in ontology-based search is suggested to be overcoming the
shortcomings of keyword search (Khan et al., 2004). At least it eliminates lists of
words that are not domain specific. It is highly domain specific and context based,
thereby eliminating unnecessary retrieval of information. It is an efficient, timesaving
method.
In this research we explored the basic patterns of adult spelling errors and researched
the spelling error corrector to see what technique has been used. In addition, we
present an evaluation of some existing medical spell correctors to test if they meet
users??™ needs. We describe an ontology-based, spell checker architecture that would
assist users with medical information retrieval.
Review.of.Spell.Check.Approaches
The literature on misspelling is diverse and much of it is based on studies of children.
However, very little has been studied on adults. Review of papers show that
spelling mistakes in adults are predictable (Yannakoudakis & Fawthrop, 1983).
This section describes the types of spelling errors and the existing approaches to
their correction.
