# **DadmaTools**
DadmaTools is a repository for Natural Language Processing resources for the Persian Language. The aim is to make it easier and more applicable to practitioners in the industry to use Persian NLP, and hence this project is licensed to allow commercial use. The project features code examples on how to use the models in popular NLP frameworks such as spaCy and Transformers, as well as Deep Learning frameworks such as PyTorch. Furthermore, DadmaTools support common Persian embedding and Persian datasets.
for more details about how to use this tool read the instruction below.
## NLP Models
Natural Language Processing is an active area of research, and it consists of many different tasks.
The DadmaTools repository provides an overview of Persian models for some of the most basic NLP tasks (and is continuously evolving).
Here is the list of NLP tasks we currently cover in the repository. These NLP tasks are defined as pipelines. Therefore, a pipeline list must be created and passed through the model. This will allow the user to choose the only task needed without loading others.
Each task has its abbreviation as follows:
- Named Entity Recognition: ```ner```
- Part of speech tagging: ```pos```
- Dependency parsing: ```dep```
- Constituency parsing: ```cons```
- Chunking: ```chunk```
- Lemmatizing: ```lem```
- Tokenizing: ```tok```
- Normalizing
**Note** that the normalizer can be used outside of the pipeline as there are several configs (the default config is in the pipeline with the name of def-norm).
**Note** that if no pipeline is passed to the model, the tokenizer will be loaded as default.
### Use Case
<!-- These NLP tasks are defined as pipelines. Therefore, a pipeline list must be created and passed through the model. This will allow the user to choose the only task needed without loading others.
Each task has its abbreviation as following:
- ```ner```: Named entity recognition
- ```pos```: Part of speech tagging
- ```dep```: Dependency parsing
- ```cons```: Constituency parsing
- ```chunk```: Chunking
- ```lem```: Lemmatizing
- ```tok```: Tokenizing
Note that the normalizer can be used outside of the pipeline as there are several configs.
Note that if no pipeline is passed to the model the tokenizer will be load as default. -->
### Normalizer
cleaning text and unify characters.
Note: None means no action!
```python
from dadmatools.models.normalizer import Normalizer
normalizer = Normalizer(
full_cleaning=False,
unify_chars=True,
refine_punc_spacing=True,
remove_extra_space=True,
remove_puncs=False,
remove_html=False,
remove_stop_word=False,
replace_email_with="<EMAIL>",
replace_number_with=None,
replace_url_with="",
replace_mobile_number_with=None,
replace_emoji_with=None,
replace_home_number_with=None
)

### Pipeline - Tokenizer, Lemmatizer, POS Tagger, Dependancy Parser, Constituency Parser
```python
import dadmatools.pipeline.language as language
# here lemmatizer and pos tagger will be loaded
# as tokenizer is the default tool, it will be loaded as well even without calling
pips = 'tok,lem,pos,dep,chunk,cons'
nlp = language.Pipeline(pips)
# you can see the pipeline with this code
print(nlp.analyze_pipes(pretty=True))
# doc is an SpaCy object
doc = nlp('از قصهٔ کودکیشان که می‌گفت، گاهی حرص می‌خورد!')
```
[```doc```](https://spacy.io/api/doc) object has different extensions. First, there are ```sentences``` in ```doc``` which is the list of the list of [```Token```](https://spacy.io/api/token). Each [```Token```](https://spacy.io/api/token) also has its own extensions. Note that we defined our own extension as well in DadmaTools. If any pipeline related to the specific extensions is not called, that extension will have no value.
To better see the results which you can use this code:
```python
dictionary = language.to_json(pips, doc)
print(dictionary)
```
```python
[[{'id': 1, 'text': 'از', 'lemma': 'از', 'pos': 'ADP', 'rel': 'case', 'root': 2}, {'id': 2, 'text': 'قصهٔ', 'lemma': 'قصه', 'pos': 'NOUN', 'rel': 'obl', 'root': 10}, {'id': 3, 'text': 'کودکی', 'lemma': 'کودکی', 'pos': 'NOUN', 'rel': 'nmod', 'root': 2}, {'id': 4, 'text': 'شان', 'lemma': 'آنها', 'pos': 'PRON', 'rel': 'nmod', 'root': 3}, {'id': 5, 'text': 'که', 'lemma': 'که', 'pos': 'SCONJ', 'rel': 'mark', 'root': 6}, {'id': 6, 'text': 'می\u200cگفت', 'lemma': 'گفت#گو', 'pos': 'VERB', 'rel': 'acl', 'root': 2}, {'id': 7, 'text': '،', 'lemma': '،', 'pos': 'PUNCT', 'rel': 'punct', 'root': 6}, {'id': 8, 'text': 'گاهی', 'lemma': 'گاه', 'pos': 'NOUN', 'rel': 'obl', 'root': 10}, {'id': 9, 'text': 'حرص', 'lemma': 'حرص', 'pos': 'NOUN', 'rel': 'compound:lvc', 'root': 10}, {'id': 10, 'text': 'می\u200cخورد', 'lemma': 'خورد#خور', 'pos': 'VERB', 'rel': 'root', 'root': 0}, {'id': 11, 'text': '!', 'lemma': '!', 'pos': 'PUNCT', 'rel': 'punct', 'root': 10}]]
```
```python
sentences = doc._.sentences
for sentence in sentences:
text = sentence.text
for token in sentences:
token_text = token.text
lemma = token.lemma_ ## this has value only if lem is called
pos_tag = token.pos_ ## this has value only if pos is called
dep = token.dep_ ## this has value only if dep is called
dep_arc = token._.dep_arc ## this has value only if dep is called
sent_constituency = doc._.constituency ## this has value only if cons is called
sent_chunks = doc._.chunks ## this has value only if cons is called
ners = doc._.ners ## this has value only if ner is called
```
**Note** that ```_.constituency``` and ```_.chunks``` are the object of [SuPar](https://parser.yzhang.site/en/latest/) class.
### Loading Persian NLP Datasets
We provide an easy-to-use way to load some popular Persian NLP datasets
Here is the list of supported datasets.
| Dataset | Task
| :----------------: | :----------------:
| PersianNER | Named Entity Recognition |
| ARMAN | Named Entity Recognition
| Peyma | Named Entity Recognition
| FarsTail | Textual Entailment
| FaSpell | Spell Checking
| PersianNews | Text Classification
| PerUDT | Universal Dependency
| PnSummary | Text Summarization
| SnappfoodSentiment | Sentiment Classification
| TEP | Text Translation(eng-fa)
| WikipediaCorpus | Corpus
| PersianTweets | Corpus
all datasets are iterator and can be used like below:
```python
from dadmatools.datasets import FarsTail
from dadmatools.datasets import SnappfoodSentiment
from dadmatools.datasets import Peyma
from dadmatools.datasets import PerUDT
from dadmatools.datasets import PersianTweets
from dadmatools.datasets import PnSummary
farstail = FarsTail()
#len of dataset
print(len(farstail.train))
#like a generator
print(next(farstail.train))
#dataset details
pn_summary = PnSummary()
print('PnSummary dataset information: ', pn_summary.info)
#loop over dataset
snpfood_sa = SnappfoodSentiment()
for i, item in enumerate(snpfood_sa.test):
print(item['comment'], item['label'])
#get first tokens' lemma of all dev items
perudt = PerUDT()
for token_list in perudt.dev:
print(token_list[0]['lemma'])
#get NER tag of first Peyma's data
peyma = Peyma()
print(next(peyma.data)[0]['tag'])
#corpus
tweets = PersianTweets()
print('tweets count : ', len(tweets.data))
print('sample tweet: ', next(tweets.data))
```
get dataset info:
```python
from dadmatools.datasets import get_all_datasets_info
get_all_datasets_info().keys()
#dict_keys(['Persian-NEWS', 'fa-wiki', 'faspell', 'PnSummary', 'TEP', 'PerUDT', 'FarsTail', 'Peyma', 'snappfoodSentiment', 'Persian-NER', 'Arman', 'PerSent'])
#specify task
get_all_datasets_info(tasks=['NER', 'Sentiment-Analysis'])
```
the output will be:
```json

### Loading Persian Word Embeddings
download, load and use some pre-trained Persian word embeddings.
dadmatools supports all glove, fasttext, and word2vec formats.
```python
from dadmatools.embeddings import get_embedding, get_all_embeddings_info, get_embedding_info
from pprint import pprint
pprint(get_all_embeddings_info())
#get embedding information of specific embedding
embedding_info = get_embedding_info('glove-wiki')
#### load embedding ####
word_embedding = get_embedding('glove-wiki')
#get vector of the word
print(word_embedding['سلام'])
#vocab
vocab = word_embedding.get_vocab()
### some useful functions ###
print(word_embedding.top_nearest("زمستان", 10))
print(word_embedding.similarity('کتب', 'کتاب'))
print(word_embedding.embedding_text('امروز هوای خوبی بود'))
```
The following word embeddings are currently supported:

To get started using DadmaTools, simply install the project with pip:
```bash
pip install dadmatools
```
Note that the default installation of DadmaTools **does** install other NLP libraries such as SpaCy and supar.
You can check the `requirements.txt` file to see what version the packages has been tested with.
### Install from github
Alternatively you can install the latest version from github using:
```bash
