docker-opennlp

A Docker image for OpenNLP.

How to use this image

Build

docker build -t opennlp-docker .

Run

Sentence detection

Given an a file called input.txt with the following text:

This is the first sentence. This is the second sentence. And the third.
Also the fourth sentence. And the fifth sentence.

Run the following to segment the sentences (from the same directory as input.txt):

docker run --rm -i -v $PWD:/usr/src/myapp opennlp-docker SentenceDetector /models/en-sent.bin < input.txt

This will produce the following output:

Loading Sentence Detector model ... done (0.061s)
This is the first sentence.
This is the second sentence.
And the third.
Also the fourth sentence.
And the fifth sentence.



Average: 833.3 sent/s 
Total: 5 sent
Runtime: 0.006s
Execution time: 0.078 seconds

If you'd like to get the split sentences in a separate file, redirect the output:

docker run --rm -i -v $PWD:/usr/src/myapp opennlp-docker SentenceDetector /models/en-sent.bin < input.txt > output.txt

The following models are included in the image (in the /models directory):

• en-sent.bin
• en-ner-person.bin
• en-ner-organization.bin

To use any other model, you'll need to either download it or train it and load it in yourself.
