Create New Classes
- Theory: Attribute patterns can be detected which identify potential classes
- Practice: Recursive partitioning of existing classes
As I mentioned, sometimes we need to create a new class to group old terms with new ones. The theory is that we can use the semantic attribute knowledge to help us recognize patterns of meaning. In practice, what this means is recursive partitioning of a class. Theoretically, if the terms are similar enough, they should be in the same class, so all we have to do is select a class with more than two children and see if the children can be partitioned into two nonempty sets, based on their attribute similarities and differences.
