Preferences window – Discover Relationships

Use this window to specify the default settings and algorithm preferences to use to find relationships between a source and target in the mapping editor.

General page

Use this page to specify whether the Scope window opens when you find relationships and to specify the number of similar matches to find.

Show the Scope window when you look for relationships
Select this check box if you want the Scope window to open each time you find relationships between a source and target in the mapping editor. By default, this setting is enabled.
Find similar match
Specify the number of similar matches that you want to find in the Number of matches field. Select the For each selected source element radio button or the For each selected target element radio button to specify whether you want to find matches for the source or target.

Algorithms page

Use this page to specify the algorithms to use to find relationships.

Algorithm
Select the check box for the algorithm that you want to use when finding relationships. You can select multiple algorithms and configure the values for each one. The default algorithm is Lexical similarity.
Configuration for Lexical similarity algorithm
Set the rejection threshold for the Lexical similarity algorithm. The recommended value is 1.
Composition by sequence
If you selected more than one algorithm, specify the order in which you want the algorithms applied to find relationships. To change the order, highlight an algorithm and click the Move Up push button or the Move Down push button. The recommended order is to place Lexical similarity first. Composition by sequence is the default setting.
Composition by weight
If you selected more than one algorithm, select this radio button to specify the percentage for each algorithm. By default, each algorithm is weighted equally.
