How to do it…
To set things up, we have to load the models and bind them to function names. To load the
models, we'll use the
opennlp.nlp/make-name-finder
function. We can use this to load
each recognizer individually, as follows:
(def get-persons
(nlp/make-name-finder "models/en-ner-person.bin"))
(def get-orgs
(nlp/make-name-finder "models/en-ner-organization.bin"))
(def get-date
(nlp/make-name-finder "models/en-ner-date.bin"))
(def get-location
(nlp/make-name-finder "models/en-ner-location.bin"))
(def get-money
(nlp/make-name-finder "models/en-ner-money.bin"))
Now, in order to test this out, let's load the latest SOTU address in our corpus. This is Barak
Obama's 2013 State of the Union:
(def sotu (tokenize (slurp "sotu/2013-0.txt")))
We can call each of these functions on the tokenized text to see the results, as shown here:
