Reconfiguring the Matching Logic

If the results of the match analysis show that you need to modify the query, thresholds, or match string, you can make the changes to the IBML Tool configuration file and run the Bulk Matcher again to analyze the new settings. Once you are satisfied with the new settings, you need to update the master index application configuration accordingly.

To Reconfigure the Matching Logic

1. Complete the match analysis, as describe under Reviewing the Match Analysis Results.

2. In the directory where the IBML Tool is located, open conf/loader-config.xml.

3. To modify the match and duplicate thresholds for match analysis, enter new values for the duplicateThreshold and matchThreshold elements.

4. To modify the blocking query for match analysis, modify the query builder section (described in Initial Bulk Match and Load Tool Blocking Query Configuration).

5. To modify the match string for match analysis, modify the MatchingConfig section (described in Initial Bulk Match and Load Tool Match String Configuration).

6. Run the match analysis again, as described in Running the Bulk Matcher in Analysis Mode.

7. After you run the analysis for the final time, continue to Performing the Bulk Match.

   Caution –

   When you complete the analysis and have made the final modifications to the blocking query, matching string, and match thresholds, be sure to modify the master index application so the processing is identical. The match string is defined in mefa.xml, the thresholds are defined in master.xml, and the blocking query is defined in query.xml. You can copy the configuration from loader-config.xml directly into these files.
