# monocleaner

![License](https://img.shields.io/badge/License-GPLv3-blue.svg)

Monocleaner is a Python tool that aims to detect disfluent sentences in a monolingual corpus.
Each sentence is assigned a fluency score between 0 and 1, with higher scores indicating more fluency.
In addition to a continuous score, several handwritten rules assign a score of 0 to obviously poor sentences.

Although a training tool (`monocleaner-train`) is provided, you may want to use the available ready-to-use language packages.
Please, visit https://github.com/bitextor/monocleaner-data/releases/latest or use `monocleaner-download` to download the latest language packages.

## Installation & Requirements
Monocleaner uses [FastSpell](https://github.com/mbanon/fastspell) that requires `python-dev`:
```bash
sudo apt install python-dev
```

Monocleaner can be installed using `pip`:

```bash
python3 -m pip install monocleaner
```

Monocleaner requires the [KenLM](https://github.com/kpu/kenlm) Python bindings with support for 7-gram language models. You can easily install it by running the following commands:

```bash
git clone https://github.com/kpu/kenlm
cd kenlm
pip install --config-settings="--build-option=--max_order=7" .
mkdir -p build && cd build
cmake .. -DKENLM_MAX_ORDER=7 -DCMAKE_INSTALL_PREFIX:PATH=/your/prefix/path
make -j all install
```

The remaining extra modules required by Monocleaner will be automatically downloaded and installed/upgraded (if required) with the first command.

After installation, two binary files (`monocleaner-train` and `monocleaner`) will be located in your `python/installation/prefix/bin` directory. This is usually `$HOME/.local/bin` or `/usr/local/bin/`.

## Scoring
`monocleaner` aims to detect disfluent sentences in a monolingual corpus.
Each sentence is assigned a fluency score between 0 and 1, with higher scores indicating more fluency.
In addition to a continuous score, several handwritten `hardrules` assign a score of 0 to obviously poor sentences.

The input file (monolingual corpus) must contain one sentence per line text.
The generated output file will contain the same lines adding a column containing the Monocleaner fluency score.

This tool can be run with
```bash
monocleaner [-h]
            [--disable_minimal_length]
            [--disable_hardrules]
            [--score_only]
            [--annotated_output]
            [--add_lang_ident]
            [--debug]
            [-q]
            model_dir [input] [output]
```
If input and output are omitted, it will read from stdin and write to stdout.

### Parameters
* Positional arguments:
  * `model_dir`: Directory where the model is stored.
  * `input`: Input text file, one sentence per line. When omitted jointly with output, it will read from stdin.
  * `output`: Output tab-separated text file adding monocleaner score. When omitted output will be written to stdout.
* Optional arguments:
  * `--score_only`: Only output one column which is the monocleaner score (default: False)
  * `--add_lang_ident`: Add another column with the identified language if it's not disabled.
  * `--disable_hardrules`: Disables the hardrules filtering (only monocleaner fluency scoring is applied) (default: False)
  * `--disable_minimal_length` : Don't apply minimal length rule (default: False).
* Logging:
  * `-q, --quiet`: Silent logging mode (default: False)
  * `--debug`: Debug logging mode (default: False)
  * `-v, --version`: show version of this script and exit

### Example
```bash
monocleaner models/es mono.es.txt mono.es.scored.txt
```

This will use the Spanish model located at `models/es`, read `mono.es.txt` file and write the sentences to `mono.es.scored.txt` adding the monocleaner score column.
