Example - Add SD-Rules from Other Suggestions

Other suggested SD-Rules can be evaluated and added to this system by following the same approach in the previous two sessions: nomD session and factD session.

  • Suggested SD-rules:

  • Apply the same procedures to get the optimized set by using the latest optimized set of 2.3.4.5 as new baseline. This task involves:
    • Retrieve all raw SD-pairs from Lexicon (2013) of above four selected SD-rules
    • Tag raw SD-pairs
    • Get stats of SD-pairs of these four SD-rules
    • Add to SD-rules set and find the optimization
      • Check if root parent-rule
    • The total valid SD-Pair no. (TotalYes) needs to be calculated as total valid SD-pair no. from all parent-rules.

    The iterative results are shown as follows:

The result shows the new selected SD-rule does not improve the system performance and should not be included in the optimized set. However, this SD-rule is added to the SD-rules evaluation set to cover more evaluated SD-rules. The new optimized set has coverage rate (95.01%) and system performance (1.9031) with accuracy rate of 95.30% to include 73 (out of 96) SD-rules. This set should be used as baseline for evaluating new rules in the future. The diagram below shows the system accuracy and coverage curves of this optimized set.
