    All 87 good SD-Rules in 2017 are evaluated as good rules in 2020. They could be identical, or replaced by the parent-rules or child-rules.

  • Good SD-Rules count in Optimal Set:
    • 2017 has 86 good rules while 2020 has 93 good rules in optimate set:
    • From the evaluation, 7 of 11 new rules are good (4 bad; 7 duplicated are not included). The total number of good SD-Rule is increased by 7 (from 86 to 93), because:
      • no duplicated rule are in the new Sd-rules for evaluation
      • no new rules have parent-child relationshion with existing rule

  • Good Rules comparison (2017-2020):

  • In our process, we only analyze parent-child hierachy for those SD-Rules has parent-child relationship co-exist in the collected set because it is very expensive (time comsuming) to evaluate all parent-child rules. Shoule we modify the processes as:
    • Normalize all SD-Rules to it's root-parent-rule.
    • Analyze parent-child-hieracy for all SD-Rules.

    in 2020, we spent 2 weeks to evaluated 18 parents rules and 12 new Rule (root parent-rules). If we modify to this process, there will be 101 parents rules, very expensive!!

The conclusion is the optimized set of SD-Rules is very steady as we expected. We believe this is one of the component that implies that Lexicon is a good representative subset of general English.
