To reuse the classifier serialized in the previous section, use the
AbstractExternal-
izable
class'
readObject
method as shown here. We will use the
LMClassifier
class instead of the
DynamicLMClassifier
class. They both support the
classify
method but the
DynamicLMClassifier
class is not readily serializable:
LMClassifier classifier = null;
try {
classifier = (LMClassifier)
AbstractExternalizable.readObject(
new File("classifier.model"));
} catch (IOException | ClassNotFoundException ex) {
// Handle exceptions
}
In the next code sequence, we apply the
LMClassifier
class'
classify
method.
This returns a
JointClassification
instance, which we use to determine the best
match:
JointClassification classification =
classifier.classify(text);
System.out.println("Text: " + text);
String bestCategory = classification.bestCategory();
System.out.println("Best Category: " + bestCategory);
For the
forSale
text, we get the following output:
Text: Finding a home for sale has never been easier. With
Homes.com, you can search new homes, foreclosures,
multi-family homes, as well as condos and townhouses for
sale. You can even search our real estate agent directory
