Norm System Options

Normalize text. This process involves abstracting away from case, inflection, and word order. It also involves removing stop words, possessives, replacing punctuation with spaces, remove parenthetic plural forms of (s), (es), (ies), (S), (ES), and (IES), and non-ASCII Unicode to ASCII normalization from the input term. Specifically, this normalization is the lvg flow options -f:q0:g:rs:o:t:l:B:Ct:q7:q8:w. That is, map Unicode symbols and punctuation to ASCII, 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 get citation form for each base form, then Unicode Core Norm, then strip or map non-ASCII Unicode characters, and finally sort words in alphabetic order.
