Saved as person-train.txt:
  6. 6. Create Training Definition File An XML file that describes the model training. <?xml version="1.0" encoding="UTF­8"?> <trainingdefinition xmlns=""> <algorithm cutoff="1" iterations="1" /> <trainingdata file="person­train.txt" format="opennlp" /> <model file="/tmp/persons.bin" encryptionkey="enckey" language="eng" type="person" /> <features> <generators> <cache> <generators> <window prevLength="2" nextLength="2"> <tokenclass /> </window> <window prevLength="2" nextLength="2"> <token /> </window> <sentence begin="true" end="true" /> </generators> </cache> </generators> </features> </trainingdefinition> Saved as training-definition.xml:
  7. 7. Create Persons Entity Model # SSH to the Idyl E3 instance. ssh ­i <key> ec2­user@<Public_Ip> # Train the model. cd /opt/idyl­e3/bin ./train­entity­ training­definition.xml # Copy the generated model and its manifest. cp /tmp/model.bin ../models/ cp /tmp/model.manifest ../models/ # Restart Idyl E3 to use the model. sudo service idyl­e3 restart
