I, <START:person> Dawson Garth <END>, don’t remember that. <START:person> London Alexander <END> was a country music singer. One annotated sentence per line. More data improves training. 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="http://www.mtnfog.com"> <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 ./train­entity­model.sh 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
  8. 8. Using the Entity Model Idyl E3 will now use the new entity model to extract entities when requests are received.
  9. 9. Entity Extraction Response {    "entities":[       {          "text":"George Washington",          "confidence":0.96,          "span":{             "tokenStart":0,             "tokenEnd":2,             "characterStart":0,             "characterEnd":17          },          "type":"person",          "languageCode":"eng",          "extractionDate":1504022495052,          "metadata":{          }       }    ],    "extractionTime":48 } An example entity extraction request and response: Response curl http://<Public_IP>:9000/api/extract  ­d “George Washington was president.” Entity Extraction Request
