## 🔔 About
StyloMetrix is a tool for creating **text representations** as **StyloMetrix vectors**. Each metric in vector quantifies a linguistic feature in text. Therefore a detailed information of the style of text can be translated to numeric values and used for - whatever you want!

The metrics are:
- **interpretable** - each metric represents an aspect of linguistic knowledge
- **normalized** - metrics express number of ocurrences of given feature per number of tokens in text, which lets us escape scaling effect in texts of different lengths
- **reproducible** - values of metrics can be recalculated or even counted manually giving always the same output. The representation doesn't depend on any random factor or seeding
- **customizable** - if your needs exceed the scope of built-in metrics, create your own! Don't forget to share your work and contribute to the community of StyloMetrix!

A StyloMetrix vector can be used as:
- **stylometric signature** that encodes the writing style of the author and the genre 
- input for classifiers of **supervised** or **unsupervised learning**, for example Random Forest classifier or feature selection algorithms
- values for **statistical analyses in science**
- set of linguistic data for manual reference

The tool offers **customization of vectors** by selecting from built-in metrics or **creating new metrics** according to user's needs. We provide a user-friendly interface to support these tasks. See instructions below! ⬇

Currently StyloMetrix is available for **English**, **German**, **Polish**, **Russian**  and **Ukrainian** language. 

## 📢 Release
Our most recent release is:

`v0.1.0`
- Changing the structure of StyloMetrix
- Works much faster!
- New metrics and categories in Polish and English language
- German language in beta version
- Russian language in beta version
- Ukrainian language in beta version
- Possibility to define metrics to use / categories of metrics as list of strings containing names.
- Possibility to save intermediate steps so even if something crashes, you still have some of work saved.

Please notice that support for **Russian** and **Ukrainian** languages will no longer be available.

## 🔨 Installation

### 1. Install spaCy 
Install `spacy` according to [spaCy install instructions](https://spacy.io/usage) 

### 2. Install model

▶ **For Polish**:

[Download and install model](http://mozart.ipipan.waw.pl/~rtuora/spacy/) `pl_nask` `v0.0.7`

📍 `pl_nask` is the new [HerBERT](https://github.com/allegro/HerBERT) based model from IPI PAN, requires `spacy==3.3`
```bash
python -m pip install <PATH_TO_MODEL/pl_nask-0.0.7.tar.gz> 
```
▶ **For other languages**:

- For English install `en_core_web_trf` from [spaCy install instructions](https://spacy.io/usage)
- For German install `de_core_news_lg` from [spaCy install instructions](https://spacy.io/usage)
- For Russian install `ru_core_news_lg` from [spaCy install instructions](https://spacy.io/usage)
- For Ukrainian install `uk_core_web_trf` from [spaCy install instructions](https://spacy.io/usage)


### 3. Install StyloMetrix
```bash
pip install stylo_metrix
```

## 🪁 How to use
1. Get your texts and import StyloMetrix:
```python
import stylo_metrix as sm

texts = ['Panno święta, co Jasnej bronisz Częstochowy I w Ostrej świecisz Bramie!',
        'Ofiarowany, martwą podniosłem powiekę; I zaraz mogłem pieszo, do Twych świątyń progu...',
        'W ludziach straty nie było. Ale wszystkie ławy Miały zwichnione nogi;']
```
2. Use StyloMetrix object for this texts:
```python
stylo = sm.StyloMetrix('pl')
metrics = stylo.transform(texts)
print(metrics)
```
3. Your results is now in `metrics` object.

That's it! Find out about more usages and customization options in [notebook tutorial](examples/Tutorial.ipynb).

## 📈 Metrics
We have put care into creating a set of powerful built-in metrics. See the list below ⬇. However, since flexibility is strength, we provide an easy way to create new metrics.

**Polish** [(see full list)](resources/metrics_list_pl.md)

**English** [(see full list)](resources/metrics_list_en.md)

**German** [(see full list)](resources/metrics_list_de.md)

**Russian** [(see full list)](resources/metrics_list_ru.md)

**Ukrainian** [(see full list)](resources/metrics_list_ukr.md)
