Input Inflection Filter

  • Description:

    This option defines the field to use as the input inflections. This option specifies which field marks the syntactic inflections of the input term.

    This option has effects on the following flow components: b, i, ici, L, Lp, Ln, s.

    Note: The first field is 1. If this option is not specified, all syntactic inflections are applied to the input in the inflection modules. If this option is present, this field should contain a long (integer) that is formed by OR'ing (or adding) the following integers:

  • Implementation Logic:
    1. Get the specified filed number of the input inflection filter.
    2. Get the specified inflections from the input term by the specified field number.
    3. Assign the specified inflections to the source inflection of the input LexItem.
    4. Do the filtering on flows: b, i, ici, L, Lp, Ln, s.
