LuiNorm System Options

Normalize and canonicalize text. This process involves abstracting away from case, inflection, and word order. It also involves removing stop words, possessives, punctuation, remove parenthetic plural forms of (s), (es), (ies), (S), (ES), and (IES), and normalize non-ASCII Unicode to ASCII from the input term. Specifically, this normalization is more or less equivalent to the combined lvg flow options (in this order as well) -f:q7:g:rs:o:t:l:B:C:q8:w . That is, Unicode core norm then remove genitives, then remove parenthetic plural forms of (s), (es), (ies), (S), (ES), and (IES) then replace punctuation with spaces, then remove stop words, then lowercase, then uninflect each word, then take each of the uninflected words and map them to their canonical form, then strip or map non-ASCII Unicode characters, and finally word order sort.
