This is an example app for creating a Liblinear classifier from data that is stored as string valued features and string valued labels, e.g.
verb=join,noun=board,prep=as,prep_obj=director,V verb=isIs,noun=chairman,prep=of,prep_obj=N.V.,N verb=named,noun=director,prep=of,prep_obj=conglomerate,N
These are examples from Ratnarparkhi's classic prepositional phrase attachment dataset, discussed in the following homework:
http://ata-s12.utcompling.com/assignments/classification
The homework includes pointers to the data and to Scala code for generating said features.
This example uses Nak's data indexers and event streams to read in the data, and and it also tests model writing and reading.
