Max. feature length

Specifies the maximum number of characters that should be used for a feature.

Should not be larger than 64 characters.

Min. feature frequency

Specifies how often a substring must appear inside the training set of a class to be

used as a feature for content classification.

Start features at beginning of word

Specifies that a feature substring must always start at the beginning of a word. If

not checked, the substring can start anywhere.

Max. words per feature

Limits the number of words per feature. A value of zero means unlimited words,

although the total number of characters of the words per feature cannot exceed

the “Max. feature length” property.

Use fuzzy string match

Enables additional fuzziness with the disadvantage of slower classification

performance.

Fuzzy length

Configures the fuzzy string comparison.

Min. class entropy

Controls the importance of a feature, depending on the number of classes in

which it appears. A value of 1.0 requires that a feature only appears inside the

sample documents of a single class; otherwise, it is not used for classification.

The lower the value, the more classes a feature can appear inside the training set.

Note You must retrain the project before any changes in these settings take affect.
