Transcript

  • 1. Contextual Spell Checkers Effectiveness for People with DyslexiaGoogle Wave, Microsoft Office and Ghotit Comparison
  • 2. Background Information on Context Sensitive Spell Checkers
  • 3. What is a contextual spell checker?
    A Contextual Spell Checker analyzes the context of sentence in which the misspelled word appears, and based on the context of the word suggests the corrections.
    A Context Spell Checker implements Natural Language Processing (NLP) algorithms.
  • 4. What is required for an effective context spell checker?
    Advanced NLP algorithms that analyze correctly the context of a sentence and the incorrect word written in it
    An optimized scoring system that place in the correct order the relevance of the suggested corrections
    High performance system that can run in the background multiple iterations and select the most highly scored ones within mili-seconds
    A learning NLP server whose intelligence increases as more examples and data is gathered
    Self learning algorithms that take into each next iteration additional information provided by the user
  • 5. Special requirements of spell checkers by people with dyslexia (#1)
    Correction of severely misspelled words
    Regular spell checkers address mild spelling mistakes only
    Detection of misused/out-of-context words (e.g. “meat” instead of “meet”)
    Regular spell spellcheckers can not identify misused words as they have no notion of the sentence context
    Detection of grammar mistakes within a sentence of severely misspelled words
    Regular spell checkers offer some grammar correction, but only if the words comprising the grammatical error are spelled correctly
  • 6. Special requirements of spell checkers by people with dyslexia (#2)
    Assistance in selecting the correct suggested word
    People with dyslexia have difficulty in selecting the correct suggested word as they do not recognize the meaning of the suggested words based only on its spelling
    Making sure that the sentence that was written and corrected is what was intended to be written
    Assistance is required to provide confidence to the dyslexic writer, that what is written is what he intended to write
  • 7. Leading context-sensitive spell checkers
