Take a look at nltk.classify - there are a number of different classifiers
there that should do what you need.

I&#39;m developing nlp application for extracting named entities. The probl=
em with<br>
built-in nltk name entity module is that the classes are fixed.<br>
For example, if I want to create table of entities like this:<br>
TOOL - any mechinacal implement usable by human (hammer, axe, etc.)<br>
QUANTITY - any human measurment (meter, pound, inch, liter, gram, etc.)<br>
BMATERIAL - any building material (wood, brick, stone, sand, etc.)<br>
Let&#39;s say I have some tagged data in IOB form, which would be splitted =
in<br>
training and testing portions. Wordnet would be nice basis for features.<br=

Is there a way to create custom classes and their features, and then to tra=
in<br>
the algorithm with tagged data?<br>
