Step 1. Fill in the text boxes and choose "Add New Group."

SWORD takes as input an XML query. The query requests one or more groups of nodes. A group is an equivalence class of nodes with the same requirements.

Step 2. Add your desired attributes to the group request.

SWORD uses the following format for describing attributes:

   <attr>abs_min, ideal_min, ideal_max, abs_max, k</attr>

• abs_min is the required lower bound on the value
• abs_max is the required upper bound on the value
• ideal_min is the preferred lower bound on the value
• ideal_max is the preferred upper bound on the value
• k is the penalty "charged" if the value is between abs_min and ideal_min or between ideal_max and abs_max

Group:	Attribute:	abs_min,	ideal_min,	ideal_max,	abs_max,	k

Step 3: Add additional groups by repeating Steps 1 and 2.

SWORD finds disjoint groups that satisfy the requested constraints.
