Exclusive Filter Rules: Derive invalid lead units and invalid end units From Lexicon

I. Introduction

By definition, any known multiwords (in Lexicon) should not begin with an invalid lead unit. The only exception is a child word of the invalid word is the lead unit of the multiwords. For example, "above" is a lead word because there are 13 multiwords found in Lexicon that beginning with "above":

  • above cited
  • above the knee amputations
  • above knee amputations
  • above knee amputee
  • above board
  • above knee
  • above reported
  • above listed
  • above named
  • above mentioned
  • above the knee amputation
  • above knee amputation
  • above knee amputees
On the other hand, "above" is a invalid end unit because the only multiwords ends with "above" is it's parent words, "over and above", which is also an invalid end unit.

II. Source of invalid lead-end-units

  • Get the invalid lead units and invalid end units from the latest Lexicon
    • Get all multiwords from Lexicon
    • Get candidate invalid units from aux, compl, conj, det, modal, pron, prep.

    • Get child words of candidate lead-end words
    • Get invalid lead units (no multiwords that are leading by it)
    • Get invalid end units (no multiwords that are ending by it)
  • Applied to exclusive filters.

III. Algorithm

  • Get candidates of invalid lead-end-units by combining aux, compl, conj, det, modal, pron, and prep.
  • Find valid/invalid lead-end-units by excluding lead-end-unit candidates that have multiwords in Lexicon:
    • Check each LeadEndUnit candidate against Lexicon multiwords to calcualte stats as follows (and save in LeadEndUnitCandidateStatsObj):
      • if LeadEndUnit candidate matches (is) a multiword in Lexicon
        => matchNo++
      • else
        • if a multiword leads with LeadEndUnit candidate, but not leads with it's child units
          => leadNo++
        • if a multiword ends with LeadEndUnit candidate, but not ends with it's child units
          => endNo++
    • LeadEndUnitCandidateStatsObj:
      • leadNo > 0, it is a valid lead-unit
      • leadNo = 0, it is a nvalid lead-unit
      • endNo > 0, it is a valid end-unit
      • endNo = 0, it is a invalid end-unit
      • matchNo must be 0 or 1, it does not matter on leadUnit or endUnit
        • 0: if lead-end-unit candidate is not a multiword in Lexicon (it is a single word)
        • 1: if lead-end-unit candidate is a multiword in Lexicon
    • Results: invalid Lead-Units and invalid End-Units, please notes that these are units (not words). Such as "as far as", "across from", etc.
