This module implements an interface for the Natural Language Processing (NLP) web service provided by http://pln.pt.
Create new object, given as argument the base endpoint for the web service.
Once the object is created, a set of methods described below can be used to access several operations in the API. All the methods return a data structure with the corresponding result, typically a list of tokens with some extra information depending on the operation used.
Tokenize the text given as argument, i.e. split the text in tokens (words by default), for more information on the tokenization operation visit http://pln.pt/api.
$ echo "A Maria tem razão ." | pln-pt tokenizer
A
Maria
tem
razão
.
Morphologic analysis for a single word, given as argument. For more information on the tagging operation visit http://pln.pt/api.
$ echo cavalo | pln-pt morph
cavalo cavalo NCMS000 0.914011 cavalar VMIP1S0 0.0859891
