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.
