# Natural language processing

This repository provides all code that is needed to build a container image for natural language processing utilizing [spaCy](https://spacy.io).

## Build image

1. Clone this repository and navigate into it:
```
git clone https://gitlab.ub.uni-bielefeld.de/sfb1288inf/nlp.git && cd nlp
```

2. Build image:
```
docker build -t sfb1288inf/nlp:latest .
```

Alternatively build from the GitLab repository without cloning:

1. Build image:
```
docker build -t sfb1288inf/nlp:latest https://gitlab.ub.uni-bielefeld.de/sfb1288inf/nlp.git
```

## Download prebuilt image

The GitLab registry provides a prebuilt image. It is automatically created, utilizing the conquaire build servers.

1. Download image:
```
docker pull gitlab.ub.uni-bielefeld.de:4567/sfb1288inf/nlp:latest
```

## Run

1. Create input and output directories for the NLP software:
```
mkdir -p /<mydatalocation>/files_for_nlp /<mydatalocation>/files_from_nlp
```

2. Place your text files inside the `/<mydatalocation>/files_for_nlp` directory. Files should all contain text of the same language.

3. Start the NLP process.
```
docker run \
    --rm \
    -it \
    -v /<mydatalocation>/files_for_nlp:/files_for_nlp \
    -v /<mydatalocation>/files_from_nlp:/files_from_nlp \
    sfb1288inf/nlp:latest \
        -i /files_for_nlp \
        -o /files_from_nlp \
        -l <languagecode>
```
The arguments below `sfb1288inf/nlp:latest` are described in the [NLP arguments](#nlp-arguments) part.

If you want to use the prebuilt image, replace `sfb1288inf/nlp:latest` with `gitlab.ub.uni-bielefeld.de:4567/sfb1288inf/nlp:latest`.

4. Check your results in the `/<mydatalocation>/files_from_nlp` directory.
