Generate Antonyms

  • Short Description: Generate antonyms

  • Full Description:

    This flow retrieves all antonyms of the input from the antonym table in the database.

    The results are sorted in the order of a case sensitive alphabetical, then EUI.

    The detail information (-m option) of the antonym records shows the type, negation, domain and source of antonyms. The format is:
    |FACT|Key (lcNoPunc)|Antonym-1|EUI-1|Antonym-2|EUI 2|Category|Type|Negation|Domain|Source

    where:

    • key (lcNoPunc): the lowercase and no punctuation of Antonym 1, used as key for database SQL query
    • Antonym-1: the first antonym (base form) of the aPair
    • EUI-1: the associated EUI for antonym-1
    • Antonym-2: the second antonym (base form) of the aPair
    • EUI-2: the associated EUI for antonym-2
    • Category: the POS of aPair. Antonyms must have the same POS. Possible values include:
      adjnounverbadvprepmodalauxprondetconj

    • Type: type of antonyms by their meaning in relation to negation, as described bellows:

    • Domain: specifies the domain that is central to human life and way of living across times and cultures (generic). Domain is used to determine if an aPair is a canonical antonym. Currently, our domain includes:
      • quality
      • existence
      • possibility
      • quantity
      • frequency
      • physical_property
      • location
      • temporal
      • size
      • temperature
    • Source: the source (model) from which the aPair is generated.

  • Implementation Logic:
    1. Remove punctuation from the input term.
      • Lowercase characters from input term.
      • Find antonyms of the input term from database by options of negation, source and type.
    2. Assign category and inflection (base) to the LexItem.
    3. Sort antonyms in a case sensitive alphabetic order, then EUI.
