Dash-Space Spelling Variants

I. Introduction

Dash-Space spVars are one of the common spVars. Dash-space spVars are a subset of spVars. Accordingly, they must meet the criteria of spVars (same meaning, POS, syntax, and pronunciation) as well as match the dash-space pattern:

  • DashSpace pattern:
    • [xxx-yyy] and [xxx yyy]
    • [xxx-yyy] and [xxxyyy]
    • [xxx yyy] and [xxxyyy]

II. Algorithm

  • Dash-Space spvars are identified by SpVar model. Some of them are not included in Lexicon (by mistakes). A program is develped to retrieve terms with such patterns and not in Lexicon (false-positive from the SpVarNorm) to enhance the SPVarNorm algorithm.
  • Dash Pattern
    • Match the pattern of [xxx-yyy] to [xxx yyy] or [xxxyyy]
    • Exlcude if the term after the last '-' is a preposition in Lexicon
    • Must have same POS
    • Exlucde duplicates from the same EUISs (duplicated by inflections)
  • Space Pattern
    • Match the pattern of [xxx yyy] to [xxxyyy]
    • Exlcude if the last word is a preposition in Lexicon
    • Must have same POS
    • Exlucde duplicates from the same EUISs (duplicated by inflections)

III. Studies on Lexicon.2015

  • Dash Pattern:
    • 233 pairs that match dash spVar pattern from SpVarNorm (false positive) on Lexicon.2015
    • They are sent to linguist to tag [Y|N] for valid and invalid spVars inthe following format:
      POSEUI-1Term-1EUI-2Term-2Tag
    • Linguist combines EUI-1 and EUI-2 if the tag is [Y]
